The entrance is at the extreme tip of Worm's Head and entry can only be gained by climbing down the Western face of the outer head.
The cave is difficult to enter and the causeway is clear for about 2.5 hours only each side of low water. A 9 metre entrance passage gives access to a chamber about 6 metres wide. There is another low passage at the end.
