Lying close to the plantations, in the rich jungles of Periyar in Thekkady is one of the world's most fascinating natural wildlife reserves - the Periyar Wildlife Sanctuary.  Spread across 777 sq.km, of which 360 sq.km is thick evergreen forest, the Periyar Wildlife Sanctuary was declared a Tiger Reserve in 1978.  Noted for its geomorphology, diversity of wildlife and scenic beauty, the Reserve attracts visitors from all over the world
The splendid artificial lake formed by the Mullaperiyar Dam across the Periyar adds to the charm of the park.  This is the only sanctuary in India where you can have the unique experience of viewing wildlife at close quarters from the safety of a boat on the lake.  The greatest attraction of Periyar, however, are the herds of wild elephants that come down to play in the lake
