On a clear day Rat Tail Falls is visible from the on the Batalugundu-Kodaikanal Ghat Road, away to the west. It appears across the valley as a long thin white strip of cascading water on a background of black rock cliff face that juts out of the foothills. 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 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 stonewalls, and some smaller falls just upstream. The river water coming to the falls, though downstream from Perumal Malai village and apparently clear, may be polluted, and visitors to the area are advised to avoid drinking it.
Access
Rat Tail Falls is considered inaccessible to the general public, as there is no road to it. The top of the falls is a rewarding and challenging hike destination. Hikers should be cautious, as two Western tourists were died in 2006 when they fell from the top of the Falls. It is possible to hike to the bottom of the falls in the dry season, beginning at the Manjalar Dam. This difficult hike proceeds along a path through Mango orchards and potato fields around the Manjalar Reservoir and up along the stream as far as a small shrine, dedicated to the GoddessKamakshi. The legend is that Kamakshi was born here at the foot of the falls in a bamboo bush and hence she is called Moonkilanai Kamakshi. This place is called Amma Machhu, meaning in the middle of a grove of teak trees. Beyond this point one must climb up along the stream, going up, over and around increasingly large boulders with difficulty, till arriving at the bottom of the falls, where there is a pool about by. The return hike is more difficult. The full hike there and back covers about and takes a full day. Manjalar Dam is at the end of Manjalar Road about north from SH-36 at Devadanapatti town beginning along Kamatchi Amman temple road.
