Hello Travelers,
Hogenakkal Falls is located in Dharmapuri district of Tamil Nadu. It is located at a distance of 180 Kms from Bangalore via Hosur - Dharmapuri route. The river which forms water fall is Cauvery. It is on the Karnataka and Tamil Nadu Border.
I did not do boating or eat fish. All I did was visited the place. May be do them later someday.
My first impression after visiting this place - Although I saw people coming as couple or family. I do not recommend it to couples or family. This place is filled with Drunkards. People keep looking at women which will make them uncomfortable. Every now and then massage guys would come and ask you if you need any massage.
You get fresh fish with masala applied and ready to fry. I guess best combo would be Rice, Rasam and fried Fish :)
One can do boating but checkout the price before hand.
I have read about many incidents of over charging for boating, vehicle getting damaged etc. Watch out for con men also. Just don't blindly believe people.
