The park covers an area of 24 square kilometres (9.3 sq mi) of extensive tropical rainforest with a number or rare and protected animals surrounding the 24 square kilometer artificial lake created by the Batang Ai hydroelectric reservoir.

The park was proclaimed in 1991, and has become increasingly popular with locals and tourists despite the lack of facilities.

The ride takes approximately about 40 minutes to Batang Ai National Park headquarters.

This national park takes strong steps in having the local communities involved in its management.

The communities have formed a cooperative called 'Kooperasi Serbaguna Ulu Batang Ai' and are helping to conserve the park.
