Pha Mo E-Daeng features an ancient bas-relief of three figures carved directly into the cliffside sandstone.
The site sits at an elevation that creates a distinct microclimate, often resulting in a sea of fog during the cool season.
The park serves as a historical monitoring point for the international border dispute regarding the Preah Vihear Temple site.
The surrounding landscape is primarily tropical dry dipterocarp forest.
Pha Mo E-Daeng is one of the few places in Thailand where ancient Khmer sandstone carvings can be viewed outside of a formal temple complex.
Khao Phra Wihan National Park is located in the Dângrêk Mountains along the Thai-Cambodian border in Si Sa Ket province. The park's most prominent natural feature is the Pha Mo E-Daeng cliff, which provides panoramic views of the Preah Vihear Temple complex situated on the Cambodian side. Visitors can explore sandstone carvings dating back to the Angkorian period, specifically the 11th-century relief depicting three figures. The park area includes dense forest terrain and localized hiking trails leading to various geological formations. It serves as a conservation area for diverse flora and fauna within the Phanom Dong Rak mountain range. The site is geographically separated from the actual Preah Vihear temple ruins by a restricted border zone.
