Periyar Tiger Reserve

South India’s most popular wildlife reserve, Periyar, encompasses 777 sq km, including a 26-sq-km 1895 artificial lake created by the British. This vast expanse – which became Kerala's first tiger reserve in 1978 (though founded as a sanctuary in 1934) – shelters wild boar, sambar, bison, langur, 2000 elephants and 35 to 40 hard-to-spot tigers. It's firmly established on both the Indian and foreigner tourist trails and known for its scenic lake cruise. But if you dig deeper, perhaps on a trek with a tribal villager or an ex-poacher, Periyar's hilly jungle scenery takes on a wild, magical feel. Bring warm, waterproof clothing.
