About 60km northeast of Munnar, this wildlife sanctuary protects deer, leopards, elephants and the endangered grizzled giant squirrel. Trekking and tree house or hut accommodation within the sanctuary are available, as well as ecotour programs like river-trekking, cultural visits (two tribal groups inhabit the sanctuary) and waterfall treks (around ₹600 per person). For details contact the Forest Information Centre in Munnar. Buses from Munnar can drop you off at Chinnar (₹40, 1½ hours), or a taxi costs around ₹1500.
Entry to the park is with a guided three-hour trek.
