Conservation by Sustainable tourism in protected area is practiced by limiting the number of visits to the selected area. Different trekking routes are carefully made with the expertise of the Eco-committee members and wildlife officer wardens. About 5 lakhs of tourists visit Periyar tiger reserve every year. To minimize the impact on the ecosystem, only a maximum number of 20 people will be allowed to participate in the Tiger Trial Programme every week. And only five visitors are allowed at a time.
The programmes are one night/ two days and two nights/ three days. The camping sites are ideally located near water sources.
