In short: Periyar Tiger Reserve in Kerala's Idukki and Pathanamthitta districts protects about 925 km2 of Western Ghats forest around Periyar Lake, with elephants, many bird species and a tiger population. It is about 4 km from Kumily and Thekkady, and visitors should follow forest department rules and avoid disturbing wildlife.

Quick facts

What makes Periyar special

Periyar combines forest, hills and a large reservoir, and it was brought under Project Tiger and later Project Elephant. The reserve is home to Asian elephants, gaur, sambar, dhole, sloth bear and lion-tailed macaque, with around 266 bird species and many reptiles, butterflies and orchids reported.

Climate and season

Temperatures range from around 15 degrees C in December and January to around 31 degrees C in April and May. The southwest monsoon from June to September brings most of the rain, so plan visits with the forecast; see how to read weather forecasts.

Visit responsibly

• Book and follow forest department programmes rather than entering the forest alone.
• Keep distance from animals and never feed them; see responsible travel in forest regions.
• Keep noise low, carry out rubbish and avoid single-use plastic.
• Confirm current activities, fees and booking with the reserve, as offerings change.

Make it a road trip

Pair Periyar with a Western Ghats drive; see a two-day Western Ghats itinerary and weekend road trips from Coimbatore.
