Haliday Island Wildlife Sanctuary

Haliday Island Wildlife Sanctuary is a protected mangrove sanctuary covering about 5.95 sq km on Haliday Island in the Sundarbans, South 24 Parganas, West Bengal. Declared in 1976, it forms part of the Sundarbans Biosphere Reserve. The sanctuary is known for its dense mangrove forests, tidal creeks and habitat for Royal Bengal Tiger, spotted deer, wild boar, rhesus macaque and diverse birdlife.

Visitors can expect a remote, uninhabited mangrove island accessible only by boat with prior forest permission. The visit is typically a guided boat safari along tidal creeks and around the island periphery, with views of dense mangrove vegetation, mudflats and wildlife such as deer, wild boar, monkeys and birds. There is a forest watchtower for observation. There are no shops, accommodation or developed trails on the island itself; exploration is restricted and conducted under forest guide supervision.
