Slovenia's sport-climbing hub, on the Karst edge 10 minutes from Koper and Trieste. The big SW-facing Velika stena (Big Wall) holds a handful of 100–150 m multipitches among its overhanging test-pieces. It is a winter and shoulder-season venue (October–April). Camp Vovk in the village is the classic base.
