Indira Gandhi Wildlife Sanctuary and National Park

Introduction: The High-Altitude Rainforest Oasis of the Western Ghats

Spanning an expansive 958 square kilometers across the Anamalai Hills in the Coimbatore district of Tamil Nadu, at elevations ranging from 300 meters to 2,513 meters (Anamudi proximity) above sea level, approximately 230 kilometers (a 5-hour drive) west of Tiruchirappalli (Trichy) and 65 kilometers from Pollachi, the Indira Gandhi Wildlife Sanctuary and National Park (renamed the Anamalai Tiger Reserve - ATR) is one of India's richest biodiversity hotspots.
