# Pa Hin Ngam National Park

Pa Hin Ngam (Thai: ป่าหินงาม) is a national park in Chaiyaphum Province, Thailand. "Hin ngam" means "beautiful stone", "pa" means "forest". The park got its name from the strange rock formations at the west end of the park. Erosion has carved several large rocks into striking and unusual shapes.
In 1985, the Tep Satit Forestry Department first surveyed the area, long popular with locals, and recommended its protection. In October 1986, Pa Hin Ngam Park was created, covering 10 km$^2$ 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 62,437 rai ~ 100 square kilometres (39 sq mi) was created on 19 September 1994, which was officially gazetted in 2007.
The park is at the boundary of the Dong Phaya Yen Mountains and the Khorat Plateau. The steep cliff at the 846 m high Sut Phan Din viewpoint affords a view into a valley of the Sonthi River and the Sap Langka Wildlife Sanctuary. The name "Sut Phan Din" (สุดแผ่นดิน) means "end of land", reflecting the steepness of the cliff. This cliff also marks the watershed between the Chao Phraya and the Mekong rivers.
* Lan Hin Ngam (ลานหินงาม) It was caused by the erosion of the soil and rocks into different shapes, which can be imagined as many kinds of objects and animals such as nails, radar, and hens.

The dipterocarp forests bloom with the purple flowers at the beginning of the rainy season in July.
* Sut Phaendin (สุดแผ่นดิน) is a steep cliff and the highest point of the Phang Hoei mountain range, two kilometres from the park office at 846 metres elevation. It is the cliff connecting between the central and northeastern regions.
