The park's terrain includes elevations rising to over 1,000 meters, offering cool weather compared to the surrounding lowlands.

The park also features diverse wildlife such as deer, wild boars, various bird species, and occasionally larger mammals like bears and gibbons. Recreation opportunities include hiking through well-maintained trails, bird watching, picnicking near waterfalls such as the charming Nam Tok Phu Sang waterfall, and bathing in the hot springs. Historically, the area was declared a national park in 2000 to preserve its unique geological and biological resources.
