Tamil Nadu State, South India. It is 975 ft (297 m) tall and is the highest waterfall in Tamil Nadu, the third highest waterfall in India and the 267th highest in the world. Thalaiyar falls also known as rat tail falls located in the Palani hills. The falls got the name of a Rat tail falls because it can be spotted as a silver line from a long distance on the way.The very edge at the top of the Falls has a low concrete wall on either side concentrating the flow of water to focus the falls into a better rat tail shape. One can walk along the wall and get near the center of the falls. Just below one wall is a large flat rock about 5 ft (1.5 m) wide. One can get down to the edge of the rock to look directly straight down to see a little river at the bottom continuing placidly through the forest. Looking back up to the side, one can watch the water in freefall, mostly silent. The noise of the crashing water below doesn't rise up. The only noise is the water pushing around the stone walls, and some smaller falls just upstream.
