Hogenakkal Waterfalls is on the river Cauvery in the Dharmapuri District of Tamil Nadu about 135 kms off of Bengaluru. Often called the "Niagara Falls of India", the Hogenakkal falls is known for the medicinal property of the water and the special boat rides. The carobonitite rocks found here are suppossed to be some of the oldest in South Asia and in the world. It is about 18 Kms from the town of Dharmapuri.
During the dry season when the water from the falls does not have strong currents, special coracles (round boats) take passengers out for rides. One can buy freshly caught fish which are sold by the gorge and also in the coracles. Hawkers selling various other items including packaged water and snacks are common here. Once out of the water the fresh fish can be given to one of the many kitchens around the fall to be cooked.
