You want Winding roads, go to Kolli hills. Its off-seat and mostly for bikers. It has 70 hairpin bends, and the roads are smooth and amazing. Its 4 -5 hrs ride from Bangalore. You can book your stay at Silverline retreat and RJ grand. Try to book them online if its a weekend
Thanks @chaitali...Kolli hills did cross my mind but I figure that it's going to be quite tiring to do this ride in a day...a two day ride to this place is what's recommended...Thank you for suggesting some places for stay as well!!
