Devarayanadurga is a very nice place to visit and for picnic too. as its just 70 km. from bengalore you can go and come back in the same day. road is also very good and clean which makes your drive smooth and well maintained. in this place you can enjoy trekking and temples visit. this temples are very good and located in a nice place as your vehicles can reach near the temple. you can carry your lunch with yourself or you can have rice with sambhar which is good for lunch. accommodation is so so. but is safe.
