Khao Ang Rue Nai Wildlife Sanctuary

Khao Ang Rue Nai Wildlife Sanctuary is a large protected lowland forest spanning five provinces in eastern Thailand, with its eastern section in Kaeng Hang Maeo District, Chanthaburi. Established in 1977, it covers about 1,078 sq km and is Thailand's largest remaining lowland evergreen forest. It is notable as a critical watershed and habitat for wild Asian elephants, gaur, and diverse birdlife, and is managed by the Department of National Parks, Wildlife and Plant Conservation.

Visitors can expect a remote, densely forested protected area with limited public access. Entry requires advance permission from the Department of National Parks, Wildlife and Plant Conservation. The sanctuary features lowland evergreen and deciduous forest, grasslands and reservoirs. Visitors with permission can observe wildlife including elephants and birds from designated areas, visit the headquarters and nature trails, and experience a quiet natural environment without commercial tourist infrastructure.
