The park covers approximately 844 square kilometers and serves as a vital watershed for the Bang Pakong River. It features the prominent Pang Sida Waterfall, which cascades down a 10-meter cliff face. The diverse topography includes dense evergreen, dry evergreen, and deciduous dipterocarp forests. Large mammals such as elephants, gaurs, and barking deer inhabit the remote interior of the park. Several hiking trails lead to scenic viewpoints and various smaller cascades throughout the terrain.
