Most visitors arrive via the Nilgiri Mountain Railway, a narrow‑gauge line that climbs from the foothills to the plateau. The journey is more than a transport hop; the train curls through mist‑shrouded valleys and offers a rare chance to watch tea pickers at work. Buy a reserved seat in the second class compartment for the best views, and plan a brief stop at the historic station where colonial-era wooden benches still line the platform. The railway’s punctuality can be affected by fog, so allow a flexible afternoon for connections to Ooty or onward to Chennai.
Coonoor’s surrounding plantations are not just scenic backdrops; they are working tea estates that still follow age‑old plucking cycles. Hiring a local guide for a half‑day walk through the tea bushes reveals the subtle differences between orthodox and CTC processing, and you’ll learn how altitude and mist shape the flavour profile. Small roadside stalls often serve freshly brewed tea straight from the kettle, a taste that can’t be replicated elsewhere. Timing the trek for early morning yields cooler air and the chance to hear birdsong echo off the ridge before the sun softens the leaves.
Beyond the well‑trodden promenade, the outskirts of Coonoor host a network of low‑key hiking paths that intersect with the town’s water supply catchments. These trails, marked only by cairns, lead to unspoiled waterfalls that dry up in summer but roar in monsoon. Hikers should carry a sachet of iodine tablets, as some routes lack potable water taps. The paths also skirt several small villages where families still weave traditional Nilgiri carpets; a quick stop at a family-run loom offers insight into a craft that predates colonial tea estates.

[edit] "1 MILE FROM THE BUNGALOW" historic milestone below Coonoor Since the time of British rule, Coonoor has served as the terminus of the Nilgiri branch of the Southern Railway zone of the Indian Railways (formerly under the Madras South-Western Railway). In its early years, the town featured a sub-magistrate's court, a hospital, three churches, several schools, a library, as well as various shops and hotels catering to Europeans. Surrounded by tea and coffee estates, Coonoor is one of the principal hill stations of then Madras Presidency, second only to Ooty in natural advantages. The European settlement was located on the upper plateau, while the native quarter was situated on the lower slopes of the valley. In the early 1800s, travelers from the plains reached Coonoor and Ooty via the Old Ooty Road. Coonoor had an Inspection Bungalow where travelers could rest. A historic milestone where the Old Ooty Road approached Coonoor was inscribed with "1 MILE FROM THE BUNGALOW". This marker indicated the distance to the Inspection Bungalow in Coonoor. The rock was unearthed in June 2025. Local historians speculate that the marker might date from the 1830s.
