This mountainous park, in two separate sections, encompasses part of the Ubol Ratana Dam reservoir and also features rock formations and waterfalls.

[1][2] Phu Kao–Phu Phan Kham National Park is located about 60 kilometres (40 mi) northwest of the city of Khon Kaen in the Ubolratana and Phu Wiang districts of Khon Kaen Province and the Non Sang district of Nong Bua Lamphu Province.

The rock formations at Ham Tang have been eroded by wind and water into unusual shapes such as a mushroom-like pillar.

The western section is also home to the Wat Phra Phutthabat Phu Kao temple which hosts rock footprints of a human and a dog.

[1] Dry evergreen forest is found only along creeks and hosts such trees as tabaek, Dipterocarpus alatus and makha.
