Geologically, Kamtal National Park is located on a huge granitic intrusion, formed in Eocene Epoch (56 to 34 Ma), in the Cretaceous sedimentary rocks (145 to 66 Ma). Thermal contact metamorphism is restricted to the zone surrounding the intrusion. So that, a wide range of various rocks include intrusive igneous rocks, and volcanic and sub-volcanic (as sills and dikes), contact metamorphic and sedimentary rocks, especially travertine (around the hot springs) are observable in a limited distance, less than 10 km length. Such a diverse lithology is very unique all over the area. Among the most significant geological features can be name from mineralization as veins contain copper and iron, fossil localities, numerous caves and plenty of dikes that occur as long dark continues walls in limestone cliffs.

Kamtal National Park contain some of most beautiful intact landscapes in the Geopark, as a last stand castle for wild life, that fortunately save its bio-diversity. Its green meadows replete with flowers mesmerizes any visitor.
