1,980 m high Doi Phu Kha, located within the parks perimeter, gives its name to the park. There are many caves in the park area. The park is named after chomphu phu kha ( Bretschneidera sinensis), a tree with attractive pink flower bunches, which together with Caryota gigas and Acer wilsonii, are rare species of plant which in Thailand can be found only in this park. There are natural rock formations on 1,837 m high Doi Phu Wae peak. The ascent takes 3 days and 2 nights. The scenery of the sea of mist and the mountain range is the reward for the trekkers who can reach Phu Wae peak.
