Phu Pha Yon national park covers 829 square kilometers of land straddling three provinces: Sakon Nakorn,
Nakorn Phanom and Mukdahan.
The park was formerly called Huay Huat; and in August 28, 2000 the name was changed to Phu Pha Yon
after an outstanding cliff with ancient paintings on it.
The park is part of the Phu Phan mountain range in Sakon Nakhon, Nakhon Phanom and Mukdahan provinces,
with elevations up to 600 meters above sea level. The hills in the are are the sources of water for several river
Huai Sai Noi and Huai Bang Sai. Huay Huat reservoir in the park is a popular spot for the local people. Around the
reservoir are beautifully shaped rock formations. A beauty of the place is the purple colored flower called
"Dohk Du Si Ta" which blooms in the rainy season.

November to January with average minimum temperature (1995 - 2000) being 16º C.
