Pa Hin Ngam (Thai: ป่าหินงาม) is a National Park in Chaiyaphum province in Thailand. The name Hin Ngam means beautiful stone, where Pa means forest.
In 1985, the Tep Satit Forestry Department first surveyed the area, long popular with the locals, and recommended its protection. In October 1986, the Pa Hin Ngam Park was created, covering 10 km² around the strange rock formations which gave the park its name. In 1993, the Forestry Department of Thailand conducted a more thorough survey including the surrounding area, and recommended that it become a national park. The national park covering 112 km² was created on September 19, 1994, which was officially gazetted in 2007.[1]
