Sawan Durga is a place for trekking .Its 50-60kms from Bangalore towards Magadi road. At the foothill Savandi Veerabhadreshwara Swamy and Narasimha Swamy temple is there.This is best for weekend gateways.But of course , you should have enough strength to go up.On top of the hill there is a beautiful Nandi statue.
