Periyar Tiger Reserve, Thekkady, is an example of nature’s bounty with great scenic charm, rich bio diversity and providing veritable visitor satisfaction. Sprawled over an area of 925 Sq .km., Periyar is one of the 48 tiger reserves in India. Zealously guarded and efficiently managed reserve is a repository of rare, endemic and endangered flora and fauna and forms the major watershed of two important rivers of Kerala, the Periyar and Pamba. Periyar National Park and Wildlife Sanctuary (PNP) is a protected area in the districts of Idukki, Kottayam and Pathanamthitta in Kerala, India. It is notable as an elephant reserve and a tiger reserve. The protected area covers an area of 925 km2 (357 sq mi). 305 km2 (118 sq mi) of the core zone was declared as the Periyar National Park in 1982.
The park is often called the Periyar Wildlife Sanctuary or Thekkady. It is located high in the Cardamom Hills and Pandalam Hills of the south Western Ghats along the border with Tamil Nadu. It is 4 km (2.5 mi) from Kumily, approximately 100 km (62 mi) east of Kottayam, 110 km (68 mi) west of Madurai and 120 km (75 mi) southeast of Kochi.
Periyar National Park lies in the middle of a mountainous area of the Cardamom Hills. In the north and the east it is bounded by mountain ridges of over 1,700 m (5,600 ft) altitude and toward the west it expands into a 1,200 m (3,900 ft) high plateau. From this level the altitude drops steeply to the deepest point of the reserve, the 100 metre valley of the Pamba River. The highest peak is the 2,019 m (6,624 ft) high Kottamalai. The Periyar and Pamba Rivers originate in the forests of the reserve.
