For those who are interested in booking tickets for activities, pre-booking online is recommended to assure entrance as some of the attractions have limited tickets. Moreover, renting a bike or car can be a better and cost-effective mode of transportation.
If you have more time, explore the Elephant Junction, Mudra Cultural Centre, and Chellarkovil viewpoint. If you have less time, skip the Spice Plantation Tour and the Periyar Wildlife Sanctuary boat ride.
