Anaimalai Tiger Reserve, Tiger reserve in Coimbatore district, India

Anaimalai Tiger Reserve is a national park in Coimbatore district, India, covering tropical jungle, shola forest, and grassland. The protected area rises through the Western Ghats to around 2400 meters (7900 feet) and includes several forest types and open plateaus.

The area was notified as the Anaimalai Wildlife Sanctuary in 1974, and its core habitats at Karian Shola, Grass Hills and Manjampatti Valley became a national park in 1989. It was declared a Project Tiger reserve in 2008 and renamed Anaimalai Tiger Reserve by a notification dated 27 June 2007. The earlier name honoured Prime Minister Indira Gandhi, who visited on 7 October 1961.

The reserve's name honours Indira Gandhi, who visited on 7 October 1961. More than 4,600 people of six indigenous communities — Kadar, Malasar, Malai Malasar, Pulaiyar, Muduvar and Eravalar — live in 34 settlements within the reserve. Topslip, the main visitor hub, takes its name from the 19th-century practice of sliding teak logs down the hillsides from there.

The main facility at Topslip offers lodging and a starting point for elephant safaris and guided walks through different forest zones. Entry is allowed between 6 AM and 6 PM, with early morning hours offering the best chances for wildlife sightings.

More than 2000 plant species grow here, including around 400 with healing properties used by local communities. Bengal tigers, leopards, Indian elephants, and rare lion-tailed macaques share this habitat across different elevations.
