The River Cauvery, which gives rise to Hogenakkal Waterfalls, serves as a natural Inter-State boundary between Tamil Nadu and Karnataka. The Cauvery enters Tamil Nadu at Hogenakkal and is considered particularly sacred at this spot. The pool into which it falls is called ‘Vagnakundam” or sacrificial pit. The carbonatite rocks in this site are considered to be the oldest of its kind in South India and one of the oldest in the world.

On the outskirts of the rural settlements are fascinating guardian deities, called Aiyanars, which are brightly coloured giant figures made of terracotta, depicting fearsome, mustachioed warriors.
The vegetation around the eco-tourism site is predominated by southern tropical mixed deciduous forests and tropical riverine forests. There are about 484 species of flora, while valuable species like Sandal, Anogeissus latifolia, etc, abound here.

After this confluence, the river changes into a series of waterfalls, which cascade from a height of about 20m (66 ft) with a misty smoke and a thunderous sound. The nomenclature of Hogenakkal comes from two Kannada words, namely, ‘Hoge,’ meaning ‘smoke’ and ‘Kal,’ meaning ‘Rocks,’ – hence the term ‘Smoky Rocks.’ It is also known as ‘Marikottayam’ by the people of Tamil Nadu.
