Hogenakkal is also described as the 'Niagara' of India, offer an exciting holiday destination for Indians and foreigners alike.

The word Hogenakal is formed of two Kannada words hoge and kal. When the water falls on the rocks it appears as if hoge (smoke) is emanating from the top of the kal (rock) because of the force of the water, hence Hogenakkal (smoking rocks). It is also called as Marikottayam by the people of Tamil Nadu.
The Kaveri is considered to form at Talakaveri in the Brahmagiri hills in Kodagu district in Karnataka and gathers momentum as the land drops in elevation. It becomes larger as various tributaries feed into it on the way down. At Hogenakkal, the Kaveri, now a large river, drops and creates numerous waterfalls as the water cuts through the rocky terrain. In places the water falls as much as 20 m (66 ft) and is said to sound like continual thunder.[citation needed] Soon after the falls the river takes a southerly course and enters the Mettur Reservoir. The river carries sediment which makes the downriver land fertile.
At Hogenakkal the river spreads out over a wide area of sandy beaches, then flows through to the Mettur Dam and creates a 60 sq mi (160 km2). lake called Stanley Reservoir. Built in 1934, this project improved irrigation and provided hydropower.
The best season to visit is soon after the monsoons, when the river is in full spate. But some tourists prefer to visit during off-season to skip the crowd. The temperature in summer varies between 23–34 °C (73–93 °F) while during the winter it is still pleasant and ranges from 13–27 °C (55–81 °F).
