Located in the Rakov Scocjan Natural Park, Zelske Jama is a fine trip along a river. The entrance is beneath a natural bridge, some 30m or so high. The cave contains some fine formations and has a second entrance in the side of an enormous shakehole in the forest.

In 1993, an exploratory trip was made to Mrzli Rov. From the beaching point, a steep slope led into a small passage, obviously little visited. A series of crawls, traverses and scrambles headed for about 200m south into a chamber which, reportedly, normally contained a pool. On this occasion, however, the floor consisted entirely of cracked mud. A small opening in the left hand wall led into another chamber with all ways on choked with mud. This area is normally flooded.
