One day is not enough to explore Hogenakkal thoroughly, so if you have more time, you can consider visiting the following attractions: Adiyamankottai Fort, Theerthamalai Temple, Kaveri River Boating, Mettur Dam, etc. If you have less time, you should skip Melagiri hills. Don't forget to wear comfortable shoes and carry drinking water and snacks. Finally, avoid visiting Hogenakkal during monsoon months due to flooding.
