Courtallam or Kuttalam, Spa of South India, is a panchayat town situated at a mean elevation of 160 m (520 ft) on the Western Ghats in Tenkasi district of Tamil Nadu bordering to Kollam district, Kerala. Many seasonal and few perennial rivers such as the Chittar River, the Manimuthar River, the Pachaiyar River and the Thamirabarani River originate in this region. The numerous waterfalls and cascades along with the ubiquitous health resorts in the area have earned it the title the Spa of South India. The falls carry a good amount of water only when there is a rain on the hills.
Peraruvi (main falls) the biggest falls in Courtallam, is about 60m high. The flow of water is interrupted by the Pongumakadal, a 19m deep crater and comes down with greatly reduced impact, making a bath safe.
In Chitraruvi (small falls), the flow is thin. Here naturally separate places for men and women are there to bathe.
At Shenbagadevi falls, the water flows through shenbaga (Michaelia champak) trees. There is also a temple there, dedicated to Shenbagadevi Amman. Shenbagadevi leads to Chitraruvi.
About 3 km from this is Thenaruvi (honey falls), 40m high and cascading between two large stones. In places where there is no water, one can see big honeycombs. Thenaruvi is very dangerous and it is restricted for public. But it is very common to see people visiting and bathing in Thenaruvi.
