   The impressive entrance lies on a hading fault which controls the whole cave. The old entrance grid reference is 30T 454778 4794361 (Datum: ETRS89).

   The entrance pitch of 10m is initially sloping at the head and drops into a chamber. A short slide reaches the head of the second pitch where the belay is out from jammed boulders. This pitch is about 6m and lands in the continuation of the rift which now drops steeply as a series of steps to an enlargement where there is a short inlet.

   The head of the third pitch requires a step out to its bolt above a free hang of about 15m. This is split by a large ledge and lands at the head of the final 90m pitch which requires a number of traverses in its drop. At the base is a small stream in a silty rift which becomes very tight after 30m.
