The drive is the attraction. From Kallar, where the ghat begins, the road folds back on itself twenty-two times in the last eighteen kilometres, tunnelling under forest canopy, brushing tea gardens and opening, bend by bend, onto bigger and bigger views. By the time you reach the top your ears have popped, the air has turned cool, and the coast you left an hour ago feels like another country. This is how to make the climb count.
The climb: 22 hairpins from Kallar
Ponmudi lies roughly 53 to 61 kilometres north-east of Thiruvananthapuram, and the character of the journey changes sharply at Kallar. The plains run gently up to the forest check-post; beyond it, the last stretch of about 18 kilometres coils through 22 marked hairpin bends to the ridge at around 1,100 metres. It is a well-surfaced but genuinely twisting road. Drive it slowly, sound your horn at blind corners, and give yourself time — this is a road to savour, not to hurry.
Motion sickness is worth planning for; the switchbacks come quickly and rarely let up. If you are prone to it, sit in front, keep your eyes on the horizon and travel with an empty-ish stomach. Fuel up in the city, because options thin out as you climb.
Golden Valley and the Kallar river
Before the hairpins begin in earnest, the Golden Valley — about a kilometre from Kallar — is the classic first stop. It is where the Kallar river runs clear and shallow over a bed of smooth, round boulders and pebbles, a landscape the hill is well known for. It is a favourite spot for a paddle and a picnic, and in the monsoon the flow swells where the river meets a tributary. Treat the water with respect: currents rise fast after rain, and the rounded rocks are slippery.
On top: viewpoints, deer park and trails
The summit area rewards slow wandering. A short walk brings you to open viewpoints where the grassland ridges roll away into haze, best caught early before the cloud rolls in. A popular deer park sits roughly 3 kilometres from the main resort area, and the surrounding slopes lace together into gentle walking and trekking trails through tea and shola. Birdwatchers do especially well here — Ponmudi is famously rich, with counts of some 283 bird species and a large share of the Western Ghats’ butterflies.
Waterfalls near the route
The approach hides a couple of cascades worth the detour. Ponmudi Falls lies about 1.5 kilometres from the hill station, while the Kallar Meenmutty Falls sit around 3 kilometres off the Kallar main road, reached on foot through forest. Check conditions locally in the monsoon, when trails and stream crossings can turn treacherous.
Timings, fees and rules
Access is regulated through the Kallar forest check-post to protect the hill, and the details shift with season and local orders, so confirm on the day. Broadly, entry is typically allowed from the morning — often around 8:00 — with the check-post generally closing to fresh entry by around 4:00 in the afternoon (indicative — confirm locally). Expect a modest per-person entry charge plus a small vehicle or parking fee, and possibly a camera fee (indicative — confirm locally). On busy weekends the authorities may cap or hold vehicles below and run a shuttle to spare the road, so arriving early pays off. Carry a valid photo ID.
