It is located in the northern part of the Yunnan-Guizhou Plateau (滇东高原) and the northwestern part of the Guizhou Plateau (贵州高原). Stretching in a northeast-southwest direction, it is a young mountain range formed by fault uplifting. Most of its composition is ancient limestone, with an average altitude of around 2,000 meters and the highest peak reaching 4,000 meters. The mountain rises 500 to 1,000 meters above the surrounding plateau.

The region is rich in karst topography, with numerous basins, deeply cut valleys, isolated hills, limestone erosion basins, and underground rivers. The scenery includes majestic karst formations like sinkholes, limestone valleys, and mysterious caves.
