Chunchunkatte is about 50 kilometers by road from Mysore. Head for KR Nagara from Mysore and then ask for direction to Chunchanakatte. You would be shown a road on your left . Then it's about 16 kilometers of ride on a road that snakes through a number of agriculture villages.
Caution: The monkeys here are very pushy and bold. Be careful with your belongings. They are always on the look to snatch bags ( for food). Be prudent and just ignore them, you'll be fine. By the way never roam around here wearing that T-shirt with banana image printed on it!
