Khlong Lan National Park

Khlong Lan National Park (อุทยานแห่งชาติคลองลาน) covers an area of some 300 km² over mountain ranges to the west of the province. The highest peak is about 1,400 metres. Of mainly virgin jungles, it is the source of several streams which flow into the Ping River. The park headquarters is near the Khlong Lan waterfall, about 60 km from town. Attractions within the park include the 95-metre high Khlong Lan Falls with scenic surroundings, and the Khlong Nam Lai Falls (น้ำตกคลองน้ำไหล), a 9-level cascade. The Kaeng Ko Roi (แก่งเกาะร้อย) is a group of rock formations jutting out of the stream looking somewhat like islands.
