This beautiful High range district of Kerala is geographically known for its Mountainous Hills and Dense Forests. For the people of Kerala, Idukki is always associated with Power Generation. About 66% of the State's Power needs come from the Hydroelectric Power Projects in Idukki. Idukki accounts for 12.9 percent of the area of Kerala and only 3.7 percent of the population of Kerala. About 50% of its area is Reserved Forests. The pride of Kerela and a testimony to nature's splendour and human innovation, the Periyar Wildlife Sanctuary is situated on the banks of the Periyar lake - an artificial lake, at Thekkady. Here the high ranges of the Western Ghats are clothed in dense evergreen, moist deciduous forests and savannah grass lands. Below this thick green canopy roam herds of elephants, sambars, tigers, gaurs, lion tailed macaques and Nilgiri langurs.

In addition to elephant rides, cruises on the lake and treks to the ruined Mangala Devi temple - a beautiful old stone temple situated in the heart of the Thekkady forest, this sanctuary offers the unique opportunity to watch and photograph wild elephants at close quarters.

The Periyar Widlife sanctuary is spread across 777 sq km, of which 360 sq km is thick evergreen forest, the Periyar Wiild Life Sanctuary was declared a Tiger Reserve in 1978. Noted for its geomorphology, diversity of wildlife and scenic beauty, the Reserve attracts visitors all over the world and is one of the world's most fascinating natural wildlife reserves.

The splendid artificial lake formed by the Mullaperiyar Dam across the Periyar River 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 the play in the lake.
