Peppara Wildlife Sanctuary, Protected wildlife area in Western Ghats, Kerala, India.

Peppara Wildlife Sanctuary is a protected forest area in the Western Ghats featuring dense woodlands, rolling hills, and streams. The landscape supports leopards, elephants, and hundreds of bird species that depend on these forests.

The area was formerly part of the Paruthippally range of the Thiruvananthapuram territorial division, made up of part of the Palode reserve (24 km²) and part of the Kottoor reserve (29 km²). The Peppara Dam was commissioned in 1983 to augment the drinking water supply to Thiruvananthapuram city and its suburbs. In the same year, 1983, the catchment area was declared a wildlife sanctuary because of its ecological importance.

The sanctuary takes its name from the Peppara Dam, commissioned in 1983 to increase drinking water supply to Thiruvananthapuram and its suburbs. Eleven islands in the reservoir are a noted feature, and migratory birds arrive on them each year. Herds of wild elephants are regularly seen in the forest.

The sanctuary lies on the Thiruvananthapuram–Ponmudi road, about 50 km northeast of Thiruvananthapuram; the nearest railway station is 44 km away by car and the airport 49 km. The best months to visit are January to March. Annual rainfall averages 2,500 mm, so plan around the monsoon.

The reservoir inside the sanctuary holds 11 islands, and migratory birds arrive on them every year. The sanctuary also shelters 43 mammal species, 233 bird species, 46 reptiles, 13 amphibians and 27 fish.
