The Main Falls, known in Tamil as Peraruvi (the big falls), is the heart of Courtallam, the waterfall town at the foot of the Western Ghats in Tenkasi district. The Chittar river drops over a broad, dark rock face right at the edge of town, next to the old Kutralanathar Temple, and in the monsoon months thousands of people stand in line to bathe under it.
Unlike most falls in Tamil Nadu, you do not need to trek to reach it. The falls is a short walk from the bus stand and parking, which makes it the first stop for almost every visitor and the easiest one for families and older travellers.

What the Main Falls is like
The Tenkasi district administration describes the Main Falls as about 60 metres high and nearly 50 metres wide. Partway down, the water strikes a deep hollow in the rock called Pongumakadal, which breaks its force, so by the time it reaches the bathing area the fall is a heavy shower rather than a single crushing jet.
Bathing is the whole point here. Separate bathing areas and queues are kept for men and women, with railings along the rock. People believe the water is good for health because it flows through forest and herb-covered slopes before it reaches the town, a belief that gave Courtallam its old nickname, the “Spa of the South”.
Best season and water flow
Courtallam is unusual in Tamil Nadu because it is fed by the south-west monsoon, which pushes cloud and fine drizzle through a gap in the Western Ghats. This drizzle season, called saaral, usually runs from about mid-June to September and is when the Main Falls is at its best. The district administration also suggests October to January, when the north-east monsoon can refill the falls.
Outside these months the flow drops, and in a dry summer the Main Falls may be reduced to thin streams or almost nothing. Rainfall varies a lot from year to year, so ask us about the current flow before you plan a long trip just for bathing.
Safety rules and bathing bans
When heavy rain in the hills sends a sudden surge down the river, the authorities close the falls for bathing, sometimes for a day or two and sometimes longer. In August 2026, for example, bathing at the Main Falls and Five Falls was stopped for two days and then allowed again once the water receded, while the ban at Old Courtallam Falls stayed in place as a precaution. Bans are announced at short notice, so check on the day before you go.
- Follow the police and staff: do not cross railings or climb the rocks to get closer to the fall.
- No soap, shampoo or oil: these are not allowed in the bathing areas.
- Footwear: the rock is wet and smooth; walk slowly and hold the rails.
- Valuables: keep phones and wallets with someone who stays dry, as there is little safe space to leave things.
- Children: keep small children close; the force of the water is still strong in peak flow.
Kutralanathar Temple and other falls nearby
The Kutralanathar (Courtallanathar) Temple stands beside the Main Falls. It is one of the 275 Paadal Petra Sthalams praised in the Tevaram hymns, and the Chitra Sabha linked to it is one of the five sabhas of Nataraja. Many visitors bathe and then go in for darshan.
Courtallam has several other falls within a few kilometres: Five Falls (Aintharuvi), where the stream splits into five; Old Falls (Pazhaya Aruvi); Tiger Falls (Puli Aruvi); and the small Chitraruvi. Trekking falls higher up, such as Shenbagadevi and Honey Falls, have been restricted for safety at times. Our Courtallam waterfalls tour covers the main ones with a car and driver.
Visiting from Pondicherry
Courtallam is in the far south of Tamil Nadu, about 5 km from Tenkasi. From Pondicherry it is a long drive of roughly 9 to 10 hours via Trichy and Madurai, so it works best as a trip of three nights or more, or combined with Madurai on the way. The nearest railway station is Tenkasi.
Weekends and public holidays in the saaral season are extremely crowded and hotels fill up early. If you can, stay on a weekday and reach the Main Falls soon after sunrise. For more ideas, see our waterfalls page.
