In the past, the isolation of the park's location led to its use for cover by some military groups. During World War II, the Seri Thai resistance fighters used the Tham Seri Thai cave for weapons storage. And in the 1970s the People's Liberation Army of Thailand (PLAT) used the area as a hideout.
Viewpoints in the park include the west-facing Nang Mern Cliff and the Lan Sao Aee plateau.
The park has numerous waterfalls, including the multi-stage Kam Hom Waterfall, also Kreng Ka-arm and Pree-cha Suk-san waterfalls.
Some of the park's unusual rock formations include the grilled-snake-shaped Khong Ping Ngu and the 8 metres (26 ft) long Tang Pee Parn natural stone bridge.
