Krašnji Vrh is a clustered village at the southwest foot of the Žumberak Mountains. Nearby elevations include Crow Peak (Vranji vrh) and Rtič Hill. A band of marl passes through the area, which otherwise has a limestone character and karst features. Fields lie on terraces below the village. There are pastures and wooded land to the north. A karst cave known as The Man's House (Moževa hiša) or Wild Man Cave (Jama divjega moža) lies near the village, and Orehovec Spring below the village supplies drinking water.
