The grotto is one meter above sea level at the foot of a 110 meter high steep rock face and can only be visited when the sea is calm. It can be reached via a staircase with 654 steps in the almost vertical cliff, the Escala del Cabirol (German: deer ladder). Alternatively, you can take a less strenuous boat tour from Alghero or a nearby car park. Only a few hundred meters of the extensive, approximately four-kilometer-long cave system are accessible to the public. As part of a guided tour, you can view stalactite formations, calcareous sinter deposits and a small, approximately 120-meter-long saltwater lake that is connected to the sea. Explanations are given via permanently installed loudspeakers in Italian, English and German.
