Phu Kradueng mountain, made up of Jurassic and Cretaceous sandstone formations, takes the form of a mesa towering some 1000 meters above the surrounding valleys. The summit plateau is roughly square-shaped and 60 km² in size, with an average elevation of about 1250 meters.

The summit itself, located in the southwestern part of the plateau, is inconspicuous
