The name Mo Hin Khao translates to 'White Stone Basin' or 'White Stone Well', derived from the local appearance of the limestone formations.
The sandstone pillars are estimated to be around 175 to 195 million years old, dating back to the Jurassic period.
The site experiences a significant temperature drop at night, making it a popular spot for stargazing due to the lack of light pollution.
The five iconic pillars are protected within the boundaries of Phulaenkha National Park, which oversees the conservation of the geological heritage.
During the rainy season, the surrounding areas of the plateau bloom with various wild plants and ground orchids.
Mo Hin Khao, often referred to as the Stonehenge of Thailand, is a park located within Phulaenkha National Park in Chaiyaphum. The site features five massive, naturally occurring white sandstone pillars that stand prominently against the landscape. These geological formations are composed of sedimentary rocks that have been shaped by wind and rain erosion over millions of years. The area is situated on a plateau at an elevation of approximately 350 meters above sea level. Surrounding the main pillars are extensive rock fields and meadows that support seasonal wildflowers. The site is a primary geological landmark in the Isan region, showcasing unique rock weathering patterns.

Bring a high-powered flashlight if you plan to stay until dusk to navigate the uneven terrain safely.
Wear sturdy walking shoes, as the paths around the rock formations are unpaved, dusty, and filled with loose grit.
Bring a hat and sunscreen as there is very little natural shade among the pillars.
Do not wander off the marked paths into the tall grass, as the area is known for seasonal snakes and scorpions.
Do not climb on, sit on, or carve into the ancient sandstone pillars; preserve the geological surface.
