The northern part of Slovenia belongs to the southern rim of the Alps. This are the Julian Alps, which rise nearly 3,000 m, with the Triglav (2,864 m asl) being the highest mountain of Slovenia. Like all over the Northern and Southern Limestone Alps, there are numerous caves with some of them open to the public. This caves belong to the limestone of the Southern Alps, and not to the limestone of the Dinarides
The caves are really different from the cave of the Classic Karst, and only one of them is a typical alpine cave, which means huge and filled with ice. Others, located in the lower foothills are sometimes quite different as they are small and contain aragonite speleothems.
