2nd question is it possible to drive on this road? To which my answer is Yes. During monsoon I will suggest better go with a 4X4 and post monsoon any car can do but you need to drive carefully as the roads are not fenced. In my travelogue video I have recorded the parking where you can see low ground clearance cars like Kwid, Wagon R, Celerio (Automatic), Desire and Polo.
It is around 70 km from Sirsi, 22 km from Yellapur, 85 km from Hubli and around 470 km from Bangalore
