Take a private road trip from Bengaluru to Hogenakkal, where the Cauvery runs through dramatic rocky channels and waterfalls on the Karnataka–Tamil Nadu border. The route estimate is about 146 km and 3–4 hours, but the road via Hosur, Krishnagiri and Dharmapuri may vary with traffic and pickup point. Plan time for the viewing decks and riverfront. Coracle rides may operate only when local conditions allow and can be suspended for safety, so check on arrival. Confirm your preferred route, stops, current access and return timing before travel.
