This place is famous for its sunset and sunrise view points and when I went there 3 days ago, I got to know why! There is a hill called Kundadri Hill which is 8 kms away from the town Agumbe. As I saw the sun slowly rise, the beauty and the grandeur of it took my breath away!
A small tip I think you should take. While in Agumbe, stay at Dodda Mane. This is a old house with a courtyard in the middle and its sure to remind of your school vacations that you spent in your grandmother's house. The place is run by a very sweet lady. This house has another thing to boast about. The TV series Malgudi days was shot here.
