Lan Hin Ngam

Lan Hin Ngam is a vast sandstone rock terrace within Pa Hin Ngam National Park in Ban Rai, Thep Sathit District, Chaiyaphum Province, northeastern Thailand. The site is known for its expansive natural rock field with wind-eroded boulders in unusual shapes, cliff-edge viewpoints overlooking the central plains, and proximity to seasonal Siam Tulip fields. It forms the central attraction of the national park and offers panoramic scenery shaped by natural erosion.

Visitors can expect a large open sandstone terrace covered with naturally sculpted rocks of various shapes formed by wind and water erosion. The area includes walking paths across the rock field, cliff-edge viewpoints such as Sut Phaendin with views over the plains, and surrounding dry dipterocarp forest. During the rainy season, nearby fields of Siam Tulip (Dok Krachiao) bloom. The site is accessed via the national park shuttle and involves walking on uneven rock surfaces.

Lan Hin Ngam is the core natural feature of Pa Hin Ngam National Park, established in 2007 as Thailand's 105th national park to protect the sandstone plateau, rock formations and dry dipterocarp forest ecosystem of the Phang Hoei range

The rock field and Sut Phaendin cliff are locally regarded as a natural landmark marking the edge of the Khorat Plateau, and the area is culturally associated with the annual Dok Krachiao blooming festival celebrated in Chaiyaphum
