Archipelago Trail

Most people in Finland have their summer vacation between Midsummer and mid-August, when schools start. Most summer cottages see use also on weekends at least from early May and later in August. This is the best time to visit for most people: the ring road ferry connections from Houtskär to Iniö and from Nagu to Rymättylä are available, like most other services, and the weather is pleasant. In 2025 the ferry connections that enable the Rymättylä shortcut is available 9 May–14 September, as is the car ferry between Houtskär and Iniö; the other connections are available in some form year round.

Early spring and late autumn both have their own charm, and winter on an island in the archipelago can be an unforgettable experience. A visit at those times could definitively be worth considering, but this itinerary is written for a visit in season. For off season some of the services are unavailable and there are issues about weather and connections. In winter you might want to stay at some specific site instead of doing the round trip.

See Archipelago Sea for a general description.

Although the itinerary takes you from island to island, you will not be much by the shore, unless you specifically arrange it. The road mostly goes through the interior of the islands, and the ferry quay is not the place to swim or play, nor the most romantic place to watch the seascape.

There are a few official beaches on the itinerary (no guards, but no dangerous currents either – nor at any shore you choose to use), there are some nature trails by the shore, and most any cottage will be at the shore, possibly with a rowing boat to get to uninhabited islands (do not land on those with nesting waterfowl). A day at a cottage or a side trip to minor islands may be very much worth the extra time.

One reason to come to the archipelago is to enjoy the tranquillity, sit at a shore at sunset, watch the flight of terns or swallows, … These are not the experiences you will get while driving. Do find places where you can just enjoy the silence and the sounds of the wind and birds.

On the itinerary you will be on the main islands, which are much less fragile than the outer archipelago. Here there are no issues with picking wild berries or camping wild. There are quite large woods to explore if you feel like it. Normal consideration, as on the mainland, will do very well. Be cautious with fire, though: the climate is dryer and the fire brigade will not arrive as quickly. As on the mainland, open fire requires permission, but also cigarette butts, camping stoves and used matches can light a wildfire.

Some of the minor islands have identical names, as they describe not too unusual features or uses. When talking or hearing about e.g. Jurmo, Berghamn or Själö, make sure you note the context (the ones mentioned below are the more well-known, but the others may turn up locally, in timetables or otherwise). It is common to prefix ambiguous names with the former municipality name ("Nagu Berghamn", "Korpo Jurmo").

A common way to experience the Archipelago Trail is from the saddle of a bike. The distances are not too great and the bike gives you flexibility while at the same time letting you experience the landscape you are driving through better than by car. The route is very well marked, at least much of the way. The signs use names of intermediate destinations (sometimes only a minor local one), but also have the Archipelago Trail symbol. At some minor junctions there is only local signage, but these shouldn't be too confusing.

The landscape is rather flat, the roads are in good or decent condition and traffic is mostly light. The main problem is that the road is quite narrow, so where cycleways are missing you might want to get off when batches of cars are approaching, on Skärgårdsvägen timed by the ferry arrivals. You might want to avoid being on Skärgårdsvägen between Prostvik and Galtby in Friday and Sunday afternoon, as those are the busiest times.

It is possible to take the bikes on the bus (at the driver's discretion), to save time or avoid too hard exercise. Unless you are a big company or you go with the Pargas bus in peak hours, finding room for the bikes is seldom a problem – but get on at the bus station instead of a normal stop when possible, to minimize hassle. The fare for a bike is probably around €5 (depending on bus company, sometimes on distance).

There are cycleways from Turku to and through Pargas proper. After Kaarina centre until somewhere after Pargas centre the biking route often forks away from the road, as cycleway or on minor local roads (often the former route of Skärgårdsvägen). Signage is nowadays good along this leg – and you should not be more than 200 m from Skärgårdsvägen at any point, unless you take side trips, and you'll see cycleway signs (round for cycleways, square for the roads) at any crossroads. From Nagu Kyrkbacken onwards the signage is good on the Rymättylä shortcut, while signage also on the longer route should be completed in 2023.

The biking route of the trail starts at Turku castle or Turku Cathedral and leads between them by the river, from the cathedral to Hämeenkatu and by Uudenmaankatu and Uudenmaantie towards Kaarina (the signage is missing at the cathedral; just find the cycleway). You could also use the Eurovelo 10 route (which crosses the Archipelago Trail in Kaarina centre) or find your own routes through the southern residential areas, perhaps via Katariinanlaakso and the Uittamo beach.

The cycleway is paved until a few kilometres before the ferry to Prostvik. Out in the countryside after Pargas centre it changes character and starts going up and down any hill and bump. After the ferry you have to use the roads, except on shorter stretches through some villages. The detours via Gyttja and Dalkarby on Nagu Lillandet and along Norrstrandsvägen on Nagu Storlandet have little traffic, and might be nice choices. The cycleway is planned to be extended to Kyrkbacken in 2024, allowing you to get from Turku to Norrstrandsvägen along cycleways.

If you are not fit enough for biking, you are in a hurry or simply like a car better, there is nothing hindering you from using a car (or motorcycle). Driving is enjoyable, because of the scenery and the ferry connections between the islands. Remember to stop and step out often enough, to experience the surroundings more intensely.

It is possible to drive through the trail in a day by car, if you start early in the morning, but you should preferably allow two or three days, to be able to relax and actually enjoy what you see, instead of worrying about the next ferry.

You should also not drive out Friday evening or back via Pargas Sunday afternoon, as there then may be very long queues (a few hours at worst), especially at the ferry between Pargas and Nagu, as people from Turku and Helsinki drive to and from their summer cottages. Avoid going in the same direction at those times. And if you happen to be among the first driving off the ferry at peak hours, stop at first opportunity, to let the speeders pass by.

For side trips to remote islands, you should mostly leave the car at a parking lot, as capacity on ferries is limited, and there may be no parking nor road to drive at the destination.

Off season the connections between Houtskär and Iniö is served by the "remote island" ferries, some without car capacity. The connection may require staying overnight en route. In winter ferry traffic may be suspended, with connections by hydrocopter or ice road instead.

From Turku, there are buses every hour or half an hour to Pargas (lines 801 and 802) and coaches six to eight times a day to Nagu and Korpo (901–903), once to thrice a day to Houtskär (Näsby; 903) and once or twice daily to Mossala (903–904, mostly with transfer in Galtby, sometimes in Näsby; check these, as there has been great variation from year to year), all these along Skärgårdsvägen and its extensions, the main route of the itinerary. Approximate fares (adult/child 4–11): minimum (6 km) €3.30/1.70, Turku–Pargas €6/3, Turku–Nagu €12/6, Turku–Mossala €20/10. Line 801 uses city bus stops, the 9xx ones (usually with Skärgårdsbuss livery) use coach stops; line 802 is a rush hour express service and uses the motorway. All these depart from the bus station.

The routes from Turku are operated by TLO, ☏ +358 2 274-0333 (M–F 9:00–16:00). On weekends there may also be a few coaches from Helsinki directly to Pargas, Nagu and Korpo, not taking short haul passengers, operated by Vainion liikenne (possibly with the Skärgårdsvägen Ab livery). With other buses from the Helsinki direction, transfer is in Kaarina or Turku, see Pargas.

The Pargas bus is used by commuter traffic (from Kaarina and Pargas to Turku), with rush hours in the morning and after work. The Skärgårdsbuss line to Korpo and Houtskär has its peaks when people are going to (or returning from) summer cottages. Mostly there is a transfer for those going to Houtskär: either you change coaches in Galtby ferry harbour or you enter the ferry on foot and take the other coach after disembarking the ferry.

The ring road ferry between Houtskär and Iniö departs from Mossala (17 km from Näsby). Mossala has sparse bus connections, in summer 2022 once or twice daily. Another possibility is to use the ferries going from Näsby or Roslax (5 km from Näsby, on the road to Mossala) to remote minor islands – and also to Iniö a few times a week. The most practical solution when the coach does not match is to take a taxi from Näsby to Mossala, which should cost about €30–40.

In Iniö there are no buses. The distance from the ferry quay in Dalen to the main village Norrby is 3 km, which could make for a pleasant stroll. However, from Norrby to the ferry quay in Kannvik on Jumo the distance is some 7 km. There is a taxi (☏ +358 50-566-2832).

From the ferry quay in Kustavi (Heponiemi) or from Kustavi centre straight along Kustavintie, 6 km away, there are few services (three in school days; timetables as of May 2022). Check this connection and the Houtskär–Iniö one before deciding on your schedule. The operator is Taivassalon auto. "Talvi" means winter, check dates of the timetables. There may be a connection also from (or connecting to a service from) Torsholma.

There are taxis available anywhere along the route, but they are few and usually have to drive some distance to fetch you. Service around the clock is no more guaranteed. A 10-km trip can be expected to cost about €30–35, but you might want to get an estimate at time of booking (or of boarding, if you didn't book).

The ring road can be travelled by foot, and walking can easily be combined with taking the coach on some stretches. By foot you should use minor roads where possible, especially where there is no pavement/cycleway. It might be nice also to take paths through the woods for some stretches.

If going by foot you should check where to get provisions and whether you need to stock up on food and water. In season there are some summer kiosks and cafés, but outside the main season you are more or less confined to the main villages for staples. Accommodation should not be a problem, if you have a tent or book early. There are toilets on most ferries, at some ferry quays and at some nature trails and the like, in addition to those at cafés and accommodations. There is a sauna at most accommodations, something you will appreciate after a long day's walk.

The St. Olav Waterway, part of the Nidaros Path pilgrimage, goes from Turku to Korpo and continues via Åland and Sweden to Trondheim in Norway. The path was officially opened on 24 May 2019; the markings are in place and there should be adequate information available. You can get your pilgrim's passport from Turku Cathedral or online.

The St. Olav route can – if you do not want to do the pilgrimage – be used for inspiration to plan your walking route. It deviates from Skärgårdsvägen along smaller roads and uses ferries to go via minor islands. For somebody who is walking long stretches on Skärgårdsvägen the traffic can be intimidating and hinder the experience of tranquillity that is a main point in doing the walk. Taking a break while traffic from the ferry passes helps quite a bit in not getting too disturbed, but using gravel roads by the fields and pathways through the forest is better.

The pilgrimage route starts at Turku Cathedral, leads out from the centre and then follows minor roads or pathways south of the roads to Helsinki, until it reaches Skärgårdsvägen in Kaarina. It then follows the bikeway, which deviates somewhat from Skärgårdsvägen much of the way to Pargas. There it includes some sightseeing through the town. At Sattmark the route forks to either continue along Skärgårdsvägen or by the small Granviksvägen road and by ferry for accommodation on a small island, either Pensar or Björkholmen (book in advance!), continuing by ferry to Kirjais and returning to the main route on Lillandsvägen in Nagu. The ferries on the alternative route have sparse schedules and might have to be booked the preceding day.

On Nagu Lillandet the route uses Lillandsvägen across the southern part of the island. It is much more quiet than Skärgårdsvägen, although quite a bit longer. Before returning to Skärgårdsvägen it uses some even smaller roads: Laggarnäsvägen, Träskvägen and a tractor track.

Kaarina is part of the Föli bus cooperation, so here you can still get off one bus and on a later one, within two hours from boarding the first. After Kaarina centre there are few buses though, apart from those to Pargas and Korpo, and if you use a Föli ticket you have to get off before the border to Pargas (the Rävsundet bridge; last stop Jullas).

From Turku the main roads are national road 1 and regional road 110 (in Turku and Kaarina: Uudenmaantie) towards Helsinki. The latter is the formal route. Not far outside the Turku city border (2.3–3.4 km depending on route) you should turn towards "Parainen" and "Korppoo" (Finnish for Pargas and Korpo) along Paraistentie (through 2 Kaarina centre; 7.5 km), Kaarinantie (from E18) or directly to regional road 180, "the Archipelago road" (Swedish: Skärgårdsvägen, Finnish: Saaristotie). By bike you can also choose minor roads first, but as you hit Skärgårdsvägen, this is the only road for most of the distance (the turn is signposted at Paraistentie, clearly at the official route, with a single sign at the other junctions).

The three first bridges are all being replaced in 2023–2025, which means slight disruption for the traffic, but the needed detours are short and well arranged, for cars as well as for bikers. Seize the chance to see some major infrastructure projects (unless you are driving; don't cause a queue or an accident).

After Kaarina centre you will drive over the first small bridge (a new one has been built and the old one will be demolished 2024–2025) and leave the mainland for the island of Kuusisto (Swedish: Kustö). Here you have the option of a 2×6 km side trip to the 1 Kuusisto castle ruins (the bishop's castle was destroyed after the Lutheran reformation, not to offer a stronghold for the Church; 9.8 km + 6 km), the associated mansion (now Kuusiston taidekartano, "Kuusisto art mansion") and the Kuusisto church. Follow Linnanrauniontie ("Castle ruin road"), to the end for the ruins, for 2 km for the church.

On Kuusisto you will soon be out on the countryside. The traffic may still be quite heavy for the road. If you drive a car, take it easy. By bike or bus, just enjoy the landscape.

Kaarina ends with the next bridge (2 Rävsundsbron, Kirjalansalmen silta; 13.5 km), which is a sight in itself and also offers the first real archipelago views. The cycleway is a late construction, which had to be compensated by weights on the opposite side of the bridge. Take a good look; it is in the process of being replaced (2023–2025), as it wasn't built for the current heavy traffic. You may also want to note the arrangements to spare the old bridge from effects of the traffic, and the massive worksite (and that of the next bridge).

Just after the first hilltop you reach the 1 Kirjalan kahvitupa kiosk/café (15.5 km). By bike this is a good place to take a break and an ice cream (use your brakes and turn into the tunnel when you continue).

Skärgårdsvägen in Pargas is marked by white cairns, which on one hand symbolize the fairway through the archipelago, which used to be marked by such, on the other hand the limestone (Swedish: kalksten), vital to the town of Pargas.

At the 5 Lielax crossroads (17 km) you have an option for a longer side trip (2×7.5 km) to the 3 Qvidja manor on Lemlax, with a medieval keep (four storeys left); the current owners are involved in regenerative agriculture. Also on Lemland, 5 km past Qvidja, there is the apple farm 1 Tammiluoto with winery, shop and café.

Just before the next bridge, Hässundsbron (19 km; also in the process of being replaced 2023–2025), you could turn to 2 Stentorp (2×2 km side trip), a sheep farm with very nice handicraft for sale, from yarn and mittens to fur coats and woollen art, and also sheep meat in different forms. Coffee and sandwiches are served in a nice milieu and sheep are available for caressing. At some occasions, and on request for groups, there are sheep herding shows. In spring you may get the chance to bottle feed a lamb.

After the high Hässundet bridge you reach the Kalkvägen roundabout (20 km), where the town of Pargas can be thought to begin. Kalkvägen was made of concrete instead of asphalt (hence the name), as a 1970s (?) experiment by the quarry company, but is now a normal road. By car you either turn to Kalkvägen and drive to the centre that way, or continue along Skärgårdsvägen up and down the small hill, pass the supermarket Reimari, and reach the main roundabout to the centre.

The bike route turns left to Kalkvägen for a hundred metres, then forks: either continue along Kalkvägen or turn right through residential areas parallel to Skärgårdsvägen. If you choose the latter, the official route uses the right branch at a not necessarily obvious (but signposted) Y fork after the hilltop to get back to Skärgårdsvägen before the Reimari supermarket. The left branch is a shortcut through residential areas (continue straight at the first T-junction, watch out for the kerbstones); when you hit Kyrkoesplanaden you can turn to it for the church or continue for Centralparken, with a bridge close to Reimari. If you follow Kalkvägen, you will also pass by residential areas, but end up at a small roundabout in the south end of the centre instead. The latter route is a tad longer unless you aim for the southernmost part of the centre. There is signage towards Nagu from both roundabouts.

The ferry quay is in Prostvik (41.5 km) on Nagu Lillandet, the smaller of the main islands of Nagu. The landscape is rural with small villages. Simonby used to have some service. There is a longer road through the south part of the island (47.7 km + 9 km → 50.7 km). B&B Västergård is in Gyttja village by this road, as is the fork to Kirjais just south of Lillandet. Kirjais Österby has a ferry quay (12 km from Skärgårdsvägen) for the Nagu southern and transversal routes.

If you want to see the outer archipelago, you could make a return trip from Kirjais by the "Nagu southern route" ( m/s Falkö ☏ +358 400 320 097, until 29 May 2022: m/s Rosala II; map). By bike, the "Nagu transversal route" (m/s Cheri or m/s Myrskylintu ☏ +358 400 227 722; map) is usable as a means to see some more open waters on the road (get off at Mattby, Krook or Pärnäs on Nagu Storlandet in the evening, you'll then miss Nagu Kyrkbacken unless you backtrack). It is possible to camp with a tent on some of the islands, just check that you will enjoy your stay also after you are done with the sights, as you probably have to stay on a quite small island for a day or two (businesses in the neighbourhood could arrange activities or an earlier return). All these archipelago trips have to be ordered, mostly at latest 16:00 the preceding day, but they are free (no way the real costs could be covered by fees).

The next bridge takes you to Biskopsö (with cottages: Norrgård). Then comes Norrströmsbron with nice views (53.7 km; a stamp with that view, "Moln i skärgården"/"The Sound of Silence", was elected the best of the world 2018). The cycleway starts again just before Nagu Kyrkbacken, the main village of Nagu, on Storlandet. Kyrkbacken is 14 km from Prostvik, 33 km from Pargas centre and 55 km from Turku.

The ferries to Själö, Rymättylä and Norrskata call at Kyrkbacken ("Norra hamnen", i.e. by the main marina).

4 Nagu Kyrkbacken (55.6 km) has a 15th century church, a few shops and the biggest guest harbour in the Archipelago Sea (do take a look, it and its surroundings are nice). In summertime there are several accommodation options and restaurants. There is a small museum, with lots of miniatures and paintings telling about the seafaring history of the parish (ships from Nagu have sailed the seven seas, and many locals still work at sea). There are also events on many summer weekends. There is a small beach by the community centre Framnäs, past the harbour.

North of Kyrkbacken is the lush island of 4 Själö (62 km; Finnish: Seili), which used to house a leper hospital, later a psychiatric hospital. Now the Archipelago Research Institute of University of Turku is housed here (with a web camera at an ospray nest). The main sight is the wooden church from 1733, keeping the memories of sad fates. The ferry Östern to Rimito calls at the island in season, making three return trips daily, Norrskär from Turku makes a trip most days (Kyrkbacken–Själö €9/5 one way). Lodging, restaurant and other services are available since 2017 and are extended in 2023. The half-an-hour passage from Kyrkbacken is by quite narrow straits between islands, with some views to more open waters.

In season you have the option of a shortcut from Nagu Kyrkbacken via Rymättylä to Naantali. The one-hour ferry trip from Kyrkbacken to Rymättylä goes via Själö, where you probably want to have a tour, may be even stay overnight. Check your options for guided tours and ferries onward.

To Själö, halfway to Rymättylä, the voyage is through inner archipelago. After Själö you cross the open Ominaisfjärden, with the main fairway to Sweden and several other fairways (check the maze of navigational aids!). The ferry either carries you to Hanka on the other side, or continues by the shore of Rymättylä and through a sound to Röölä on the main island.

In 2021 there are four ferries serving Själö between Kyrkbacken and Rymättylä. M/S Östern has a direct route Kyrkbacken–Själö–Hanka, while M/S Norrskär on the routes Turku–Själö–Kyrkbacken and Kyrkbacken–Själö sometimes combines with M/S Hamnskär on the route Själö–Röölä. Then there is M/S Kokkomaa with one call a week at Själö in summer. All take pedestrians and bikes, while only Östern takes cars on these routes. Hamnskär is available only in peak season, Kokkomaa all year (but won't take you to Rymättylä). Östern has a café, Norrskär and Hamnskär a kiosk. Hamnskär is not accessible with wheelchair. Prices differ between the ferries, as do age limits for children. See Själö and Rymättylä for details. Arrangements will change somewhat in spring 2022.

9 Hanka (70 km; Swedish: Hanga; Luotojentie 1091) is on Aasluoto, the southernmost of Rymättylä's main islands. This is countryside. After 2.3 km you reach 10 Alakylä, the first village served by buses (on schooldays only). Luotojentie will take you to Röölä 9 km farther, via a free road ferry over Hämmärönsalmi to Airismaa, by the Kirveenrauma bridge to Nimetön ("nameless") and to the main island.

5 Röölä (81 km) is a village of one or two hundred people, 4 km south from the parish village. From here there are buses year round. From the 1950s to the 1970s it was a base for a fleet of herring trawlers making voyages on the Atlantic and returning here with their catch. A factory for pickled herring remained to 2014; its mantle was assumed by Sillikonttori in 2019 (their production marketed as artisan). There is also a museum on the herring fishing era, a museum mill, and the harbour, with marina, summer restaurant (pizzas and hamburgers) and a summer shop. Until 2011 ferries to minor islands departed from here.

The 6 Rymättylä parish village (85 km) has a medieval church and a local history museum.

There are a few businesses in Rymättylä arranging business meetings and getaways with programme services, notably Herrankukkaro. Some also arrange private celebrations such as wedding parties. 1 Ravintola Pohjakulma in Poikko (between the parish village and Merimasku) is one of the latter, serving a plentiful weekday lunch buffet (with an assortment of salmon and herring dishes along the other stuff) and a similar but a tad more festive Sunday buffet for those travelling by. They also prepare meals and cakes for take-away, if ordered in advance, and sell out some of their buffet food.

The ferry quay on the Korpo side (69.7 km) is in Retais. You will drive near the northern shore of Korpo, mostly through forest. Most sights come after Galtby (75.8 km), so you may want to make a detour, continuing at least to Kyrkoby 3 km farther.

The road from Galtby to Näsby in Houtskär is regional road 1800. From 11 Galtby ferry harbour (76.5 km) there are yellow road ferries to Kittuis in Houtskär and to Norrskata, and a bigger shiplike ferry to Åland. Off peak hours, there are departures to Houtskär about every two hours, with a gap in the traffic 24:00–06:15.

If you come by bus, you probably have to transfer here. Mostly you just get off, board the ferry by foot and get on another bus in Kittuis, but if any of the buses is going to Houtskär you should get your luggage on the bus here. There is a café on board Stella (phone: +358 400-114-291), which might serve breakfast and lunch; the other ferry on the route is Mergus, +358 400-533-461). The passage takes 30–40 minutes, partly by the main fairway towards Sweden. This is one of the passages with good views on what the archipelago is like off the main islands. You may be able to spot a white-tailed eagle or an osprey (there is even a nest on one of the big fixed navigational aids).

By car, follow the procedures from the Prostvik ferry. If there are few cars, you can stop near the middle of the ferry and thus avoid salty spray (some days you get a good share in the front of the ferry). Remember to get out and enjoy the landscape.

7 Kyrkoby is the main village of Korpo, with an old church and a local history museum.

8 Korpoström in the end of the road (8 km from Kyrkoby) has a big guest harbour, a shop and the "Archipelago centre" with exhibitions, often also workshops and seminars. There is a restaurant.

Rumar has a nature trail and an observation tower with a 5 weather radar (with an on-site display for the public).

There is a café in the 12 Kittuis ferry harbour (86 km), good if you are going towards Turku and have to wait. There is also a camping site with cottages nearby (Kittuis Camping och Caravan), and a guesthouse (Tuulenlatva).

The road will be much narrower here, but locals drive like they knew what is behind any turn (and they do, unless you or an elk happen to be there – keep to the right). There are nice villages, but not much service for tourists. In Träsk there is the Teletalo B&B.

The main village of Houtskär is 9 Näsby (95 km + 2 km), with an old church, two shops with fuel stations, guest harbour (with events some weekends), local museum (nice collection of traditional boats, try to get guiding), ferry quay, accommodation, restaurant etc. Most coaches terminate here.

To get on to Roslax, the 13 Kivimo ferry (98 km, 5 km from Näsby; also a quay for ferries to other islands) and Mossala you have to backtrack two kilometres. There is a short ferry passage between Roslax and Kivimo and a second between Björkö and Mossala. 10 Björkö (105.3 km) is a quite big village. The shop was however closed in 2016. You might still want to take a detour by foot to have a better look (the main road just passes by).

The ferry quay to get to Iniö by the ring road ferry is in 14 Mossala (109 km; 17 km from Näsby). There is probably a restaurant and cottage lodging (Mossala island resort); check, as the 2022 sanctions against Russia may have affected the business. Coaches are sparse, during the school semesters M–F Galtby 6:10 → Mossala 7:30 and Galtby 15:10 → Mossala 16:10, F Turku 16:25 → Galtby 18:40 → Näsby 19:30 → Mossala 20:05, F Sa Turku 9:15 → Galtby 11:25 → Näsby 12:15 → Mossala 12:50, Su Näsby 13:50 → Mossala 14:25 and Turku 13:15 → Galtby 15:10 → Näsby 16:00 → Mossala 16:30; 6 June–14 August 2022 M–Sa Turku 9:15 → Galtby 11:25 → Näsby 12:15 → Mossala 12:50, F 16:25 → 18:40 → 19:30 → 20:05, S Näsby 13:50 → Mossala 14:25 and 13:15 → 15:10 → 16:00 → 16:30. For most services the bus to Mossala starts at the ferry quay in Kittuis (with ferry departures given as Galtby times), some services skip Näsby, some start from Näsby.

m/s Antonia between Mossala in Houtskär and Dalen in Iniö (one hour) looks like a road ferry, but the service is not free. Adults €10, children (4–11) €5, bike €12, moped or motorcycle €25, car €40, caravan €70 (vehicle fares include passengers). Café on board. Departures four to five times daily in season only (timetables: 13 June–4 September). Vehicles should be ready 10 min before departure.

Iniö used to be the smallest municipality in "mainland" Finland (i.e. except Åland), a group of tiny islands and the surrounding archipelago – 700 km of shoreline – with some 300 inhabitants. Almost every adult had to engage in politics in some way, to fill the chairs. The tradition of doing things together, for the local community, is still strong. Modern times have had some good effects, e.g. 7–9 graders had to go to school in Turku into the 1990s, getting home for weekends, but now have a local school (originally with some lessons handled by Internet video connections to a school on the mainland as the local teachers could not handle all subjects to a high enough level).

There is a church from 1800 in Norrby (125 km).

There is a lunch restaurant, a camping site and a few lodging options in Norrby and at least a café and cottages in Kannvik. Probably some lodging options also elsewhere.

There are road ferries from the main island to Keistiö and Jumo, while shiplike ferries visit the many remote inhabited tiny islands, mostly on a daily bases. There is a road ferry on the quite long passage to Kustavi.

The ferries from Houtskär use the quays in 15 Dalen (122 km; the ring route ferry) and in the main village 11 Norrby (the ferries to remote islands). The ferries to Heponiemi in Kustavi use the quay in 16 Kannvik (131 km) on Jumo. The distance between Dalen and Norrby is 3 km, from Norrby to Kannvik 7 km.

The ferry Aura (☏ +358 400-320-093) from Kannvik to Heponiemi in Kustavi (half an hour) makes 6–8 trips daily.

Next you arrive in Kustavi, which is still in the archipelago, with lots of islands large and small, although you will drive over bridges instead of using ferries.

The 17 Heponiemi ferry harbour (137 km) is some 10 km south-east from 12 Kustavi centre, which has a wooden church from 1783. Some of the coaches from Heponiemi continue via Kustavi, others have come from Kustavi and continue towards Naantali. If you like to make the detour by coach, check. Vuosnainen (Osnäs), with ferries to Åva in Åland, is some 10 km further south-west from Kustavi, behind a road ferry. If you don't want to get back to the mainland yet, but experience more small islands, you could fork off the itinerary here and head towards Åland on said ferry. Regardless, soon after the Heponiemi ferry quay, you reach Peterzéns (138.7 km), with marina, restaurant and shop.

You might want to take a detour to the main village (9 km, adding 11 km), with grocery store, some restaurants and a medieval church. After about 3 km on Viherlahdentie towards the village you can visit the 3 Friisilä farm, with vegetables, berries etc. for sale and rabbits and chicken in the yard. From Kustavi you can continue directly onward by Kustavintie.

After the junction to Kustavi centre you can visit the "handicraft village" at 4 Kustavin savipaja, a few workshops and a local ceramics factory shop, with café. This is a 2×500 m detour; the "village" is reachable from either road.

After the border to Taivassalo you drive over a few bridges and islands, the first of them the 500-m Kaitaisten silta with nice views. You reach the mainland 3 km farther; the landscape is still very rural until you get to Naantali or Raisio outside Turku.

By the last bridge there is a nature reserve (Kuusistonrauma and Rantalanlahti) by the shore to your right, with an observation tower 1.3 km farther. Next you reach the centre of 13 Taivassalo (154 km). The church is from the 15th century.

There is a crossroads in the centre. To the north is Uusikaupunki. By car you'll continue straight along what now is Turuntie. By motorcycle, bike or foot you have the choice of turning south to Hakkeenpää instead.

By Turuntie, after 2.5 km you have the Ketarsalmen Kievari to your right, on Hylkiläntie. Regardless of whether you eat there, you could take a look at the reconstruction (by war veterans) of a dugout of the World War II eastern front and related props. Ask for the key at the restaurant, with good luck you'll get a guide. Continue towards Mietoinen and Askainen.

Turning south, you have the Viiala mansion with the local history museum after 3 km. 5 km further you reach 18 Hakkeenpää ferry quay (162 km), with sparse services: from Hakkeenpää in the summer of 2022 just 09:00 and 16:00 in weekdays and just the afternoon service in weekends. Have good clothes for the 1-hr journey, as you might want to be on the deck at least part of it. There is a beach at Hakkeenpää.

The ferry at Hakkeenpää, m/s Kaita (☏ +358 400-320-095; timetables), goes to a number of islands of 14 Velkua; to continue on the Archipelago Trail, get off at 19 Teersalo (168.3), a village with marina, restaurant, shop and municipal service. Only the southern tip of this island, Livonsaari, belongs to Velkua, but as both Velkua and Merimasku now are part of Naantali, the border isn't signposted. As you continue from Teersalo along Velkuantie, the road first leads north-eastward, then north. After 6.5 km, at the Pohjanpää junction, it turns south-east and soon crosses a strait. You are on the mainland again, for a while.

Turn right 3.5 km after the bridge (11 km after Teersalo; 179.7). The road number remains the same, but you are now on Rauduistentie; Velkuantie continues towards Askainen (7 km away). At a junction 3 km farther (182.5), those who took the mainland route will join along Merimaskuntie. Turn right for the Merimasku parish village another 3 km away, at one more strait.

On the northern route you continue through the Vakka-Suomi countryside, passing through 15 Mietoinen (now part of Mynämäki).

At the northernmost part of Mynälahti (Mietoistenlahti) you drive over the Laajoki river in the village Pyhe (172.5 km). There is a shop here. The road to the right at the end of the village leads to a nature path with birdwatching towers in the bird sanctuary around the bay shore.

Next you pass over Mynäjoki (there is a short cut from the bird sanctuary to just before the bridge) and have the (former) parish village of Mietoinen to your left (176 km). You could visit the 17th century church and the local history museum Tavastila. Otherwise, turn right to Mynämäentie (177 km) towards Askainen.

The main sight in 16 Askainen (183.6 km) is the Louhisaari manor (Villnäs slott) from 1655, 2.5 km from the junction. The Askainen Church got its present look in 1653 as manor church while the Flemings resided at Louhisaari.

The road continues south from the church, changing names to Askaistentie. At the Velkuantie junction (187.7) it changes names once more, to Merimaskuntie. At Rauduistentie (192 km) those who came via Velkua join. Merimasku parish village (195) is 11.5 km from the Askainen church.

Either way you end up in 17 Merimasku (185.5/195 km).

The wooden church is from 1726. The marina has a restaurant. There is cycleway for 4 km.

Continuing, 3 km after the parish village you reach a residential area, with a shop, before you hit Rymättyläntie, along which those taking the Little Ring Road will come (96/190/199 km). Rymättyläntie leads over the Särkänsalmi strait (cycleway being constructed as of 2022) and over Luonnonmaa to Naantali.

On Luonnonmaa you get cycleway: take Virventie 270 m after the Särkänsalmi bridge. and turn left at the T-junction with Särkänsalmentie. At the junction there is a beach. Särkänsalmentie leads east, then turns left, crosses Rymättyläntie (the cycleway makes a slight detour, just follow it) and changes names to Luonnonmaantie. Drivers who want to visit Kultaranta should turn left from Rymättyläntie.

In the summer of 2022 there was a 6 housing fair with visions about future housing in Finland, on Luonnonmaa, south of Särkänsalmentie, stretching to the Matalahti bay. Although the houses and flats aren't on display any more, you might want to take a look at modern Finnish housing, walking by the streets. The aim was to create housing in the middle of the natural environment, by the sea, without destroying too much of it, and close enough to services.

Luonnonmaantie passes Kultaranta (101/195/204 km), the summer residence of the President of Finland. The bridge from Luonnonmaa to the mainland, Ukko-Pekka, built 1934, is named after P. E. Svinhufvud, third president of the country, as is the steamer serving Naantali from Turku. After the bridge Rymättyläntie goes through a tunnel, while bikers turn left, passing the oldtown of Naantali.

With 18 Naantali (Swedish: Nådendal) you are back to urban Finland. The town is well worth a visit, but whether you have the time to do the town is up to you. As the Latin name Vallis gratiae hints, Naantali was the site of a Bridgettine abbey in medieval times. The church remains. In early to mid June you might be able to attend some concerts of the music festival (classical music).

The wooden old town is nice, overflowing with products related to the Moomin characters plus some handicrafts, and nice cafés. The town has the Moomin World theme park which may appeal considerably to visiting kids.

After visiting the centre, to drive back to Turku (121/215/224 km), follow Aurinkotie, which changes names to Raisiontie and, when you reach the border of Turku, to Satakunnantie. If you have a car and are in a hurry, Rymättyläntie will transform into the Turku bypass in Naantali, taking you to the E8 for going north or to Turku or, farther on, road 9 to Tampere, road 10 to Hämeenlinna or E18 to Helsinki.

By bike, the Achipelago Trail continues along Aurinkotie to Naantalin kylpylä (the spa hotel). Turn to the right there. From Viluluodontie, turn to Kohokuja and continue, crossing the railway. There is a nature trail and a bird observation tower at Luolalanjärvi across Armolaaksontie, road 40 (the Turku bypass). Follow it along the cycleway, pass over the bay Raisionlahti, then turn right through the underpass and continue along Naantalintie. At the Ihala crossing, turn right to Länsikaari, then left to Artukaistentie. After the bridge over Raisionjoki, turn right to follow it along Suikkilantie. By the river mouth, turn left along Pansiontie, cross the harbour railways and the cycleway to Ruissalo by a bridge, turn right to Juhana herttuan puistokatu, pass Turku castle by Vallihaudankatu, cross the railway and turn left for the centre along the Aura river. The route is probably well marked.
