Pamba river is the third largest river in Kerala. It originates from Peerumedu in Idukki and passes through the taluks of Ranni, Thiruvalla, Changanasserry and Ambalappuzha, before emptying itself into the Vembanad lake. The catchment area of the river is 1987.17 kilometres. The famous Sabarimala temple is located on the shores of Pamba. Devotees take a dip in this river at a place called Thriveni Sangamam before entering the temple and it is considered as holy as a dip in Holy Ganga. Pamba has the Poonthenaruvi waterfall which attracts many tourists. The Maramon convention, a prominent Christian gathering of Kerala, is held on Pamba’s sand banks.
