Coimbatore to Valparai

This is a road trip where the road is the destination, and it is worth being blunt about that before you go. Valparai town is a working plantation settlement — estate offices, workers'' lines, a bus stand, a handful of places to eat. There is no promenade, no boating lake, nothing to shop for. People drive up expecting an Ooty and are disappointed by lunchtime. What they have actually come for is the 64 km from Pollachi. The road leaves the plains at Aliyar dam, a gravity dam 72 m high, and then climbs 40 hairpin bends into the Anaimalai Hills to a plateau at 1,059 m. Every bend carries a reflective board naming an animal or bird found in the Anamalai Tiger Reserve, so the ascent is counted off in species rather than kilometres. The reserve is 1,479 sq km and runs from 340 m up to 2,513 m, and this is one of the few places in India where you have a real chance of seeing lion-tailed macaques from a car. Above the bends it is tea in every direction, wet enough to average 3,538 mm of rain a year, and cool enough that the maximum barely passes 29 degrees. Stay a night. The point of Valparai is being on the plateau early, when the gaur are still out on the estate roads.

Valparai exists because of tea. The plateau was cleared for planting from the 1890s onward and the ghat road was cut to serve the estates, which is why it climbs where it does and why the bends are numbered — they were working infrastructure long before they were a scenic drive. The estates are still the town: the tea company offices, the workers lines and the factory sheds are not heritage, they are the current employer.

Forty numbered hairpins above Aliyar dam, the tea plateau at 1,059 m, lion-tailed macaques and gaur beside the road, Sholayar dam, and the run on into Kerala past Athirappilly.

Sealed two-lane ghat the whole way up from Aliyar, with forty hairpin bends between the dam and the plateau. The surface is not the issue; the gradient, the blind bends and the wildlife on the road are. The climb takes about two hours from Pollachi and there is nowhere to hurry.

Get your e-pass before you leave. Since 1 November 2025 every vehicle entering Valparai needs one, and forest staff turn cars back at the Aliyar check post without it. Register at tnepass.tn.gov.in. Only 750 vehicles are allowed up on weekends under the court-ordered cap, so a weekend without a pass in hand is a wasted drive. Coming down, use engine braking and stop if you smell them. On 15 April 2026 nine people from Malappuram died when their van lost control descending this ghat, reportedly after heat built up in the brake lines. It is 40 hairpins of continuous descent and riding the pedal the whole way is how that happens. The gate shuts at 6 p.m. and does not open until 7 a.m. Time the climb so you are not arguing with a barrier in the dark. Each hairpin carries a signboard naming a species from the Anamalai Tiger Reserve — bend 9, bend 19 and the rest are effectively a field guide you drive through. Slow down at them anyway, because lion-tailed macaques cross here.

AN E-PASS IS MANDATORY. Since 1 November 2025 every vehicle entering Valparai must carry one, brought in by the Coimbatore district administration following a Madras High Court direction to regulate traffic into the Anamalai Tiger Reserve. Register at tnepass.tn.gov.in before you set out; there is provision to register at the Aliyar and Malakkappara check posts, but arriving without one on a weekend is a gamble against a 750-vehicle cap. Vehicles registered TN-41 in Pollachi and Valparai are exempt, as are government buses and essential services. THE HILLS CLOSE AT NIGHT. The Forest Department has stopped vehicles at Aliyar after 6 p.m. since August 2023, keeping tourist traffic off the ghat from 6 p.m. to 7 a.m. so wildlife can use the road. ON THE DESCENT. Nine people died on this ghat on 15 April 2026 when a van lost control coming down, reportedly from heat in the brake lines. Use a low gear, give the brakes time, and pull over if anything smells hot. ON MONKEY FALLS. It is on the ghat about 6 km above Aliyar, entry around Rs 30. It ran dry for roughly three months in early 2026 and was closed; when the rain brought it back the surge damaged the safety barriers. Whether it is open and whether there is any water in it are two separate questions, and both change. ON GOING FURTHER. From Valparai the road continues past Sholayar dam and over the state line towards Athirappilly on the Chalakudy, about 25 m high and roughly 55 km from Cochin airport, which makes a natural onward leg into Kerala rather than a return down the same forty bends.
