Hogenakkal Falls or Hogenakal Falls is a waterfall in South India on the river Kaveri. It is located in the Dharmapuri district of Tamil Nadu, about 342 km from Chennai. It is also referred to as the "Niagara of India". With its fame for medicinal baths and hide boat rides, it is a major tourist attraction.

Carbonatite rocks in this site are considered to be the oldest of its kind in South Asia and one of the oldest in the world. This is also the site of a proposed project to generate drinking water. Boating in Hogenakkal is allowed during the dry-season as the water falls are not strong enough to disrupt the passage of the boats. The best season to visit is soon after the monsoons, when the river is in full spate. During rainy Seasons the lush green ambience of Hogenakkal presents a visual feast to the tourists pouring in.

The unique sight of the tall trees mounting upon the small island-like mounds clustered with giant rocks on the way and the fiercely flowing river pounding upon it makes even the dull hearts go awe-stricken. The river water is said to have some special powers as it travels through the forests filled with herbal plants and shrubs. Overall this series of multiple falls and one of the wonderful creations of the nature is worth a visit for nature and photography lovers.
