Along the road to Khong Jiam you can cross the Pak Mun Dam to this park. After circling thickly forested Don Tana (Tana Island), linked to the mainland by two long suspension bridges, the Mun River roils through the park's beautiful namesake rapids and passes below some photogenic cliffs. In the rainy season the rapids lie under water, but towards the end of the dry season naturally cut holes in the rock, similar to those at Sam Phan Bok, emerge.
There are several good short walks from the visitor centre : the 1.5km clifftop trail to Lan Pha Phueng viewpoint is especially serene. Nam Tok Tad Ton is a wide and lovely waterfall in the far south of the park, just 300m off the main road.
There's a campsite and four bungalows . The simple restaurant opens during the day only.
By road, the park is 14km from Khong Jiam. There's no public transport, but boats in town will take you upriver and drop you at the park for a quick look around for 600B.
