This is a few hours trip from Mysore. It's better to rent a motorcycle and visit barachukki falls in the morning. While coming back, you can visit the Somnathpur temple.
I went there post monsoon and to my surprise, you can see the photos why I was surprised 😂🤣
The roads are pretty good and by bike it will take around 1. 5 hours ( a leisure ride)
I am going to visit this place again in monsoon and the onset of winter !
