The Mae Chaem River was originally called the "Salak Hin". The river created a big but narrow canyon , which is called Op Luang. The rocks and cliffs are subject to erosion by the strong currents of the river and have formed the canyon and strangely shaped rockformations. The water has to force its way past rocks and boulders obstructing the course which is a magnificent sight. The extensive, north-south running, mountain range of the park is the same as the range Doi Inthanon, the highest mountain of Thailand.
