Perumthenaruvi is a beautiful water fall situated near Ranny in Pathanamthitta District. This place can be developed as a very good eco-tourism center like Thenmala. The steeping rocks & marvelous waterfall is really a feast to the eyes. This place is not crowded. Here the rocks are not slippery. Even children can go there safely. The KSRTC is operating one service from Chengannur to Perumthenaruvi. It is regretting that KTDC is not providing even the basic facilities to the tourists.
