Travel to Thekkadi Wildlife sanctuary for a jungle safari experience. Enjoy cruising on the serene Periyar lake in the evening, keeping an eye out for wild elephants, tigers, langurs, and many other varieties of flora and fauna. After the safari, visit the Tribal Village to learn the traditions, customs, and lifestyles of the tribal residents at Thekkadi. In the evening enjoy a crazy night out with your gang around the bonfire.
If you have more time, then head to Vaigai and Vaipar for paragliding or kayaking. You can add one more day to your itinerary just for visiting Vaigai Dam and the Murugan temple.
