An entrance of 0.80X0.70 metres introduces us immediately into the base of an ascending shaft with abundant traces of erosion. A few metres further on and after a low passage, we reach another small chamber with another ascending shaft, and in the final part we find a small chamber filled with small blocks cemented to one another. Both ascending shafts communicate with each other in their upper part, first through an impassable window, and above this, through a somewhat exposed passage of larger dimensions.

Worth noting is the large quantity of flowstone in a good part of the cavity, although they are covered with mud (mondmilch), which hinders access to the upper part of the ascending shafts.
