The described starting point or access to the national park is not possible as shown (the gates are locked). Entrance is available for a fee (€9 per person) only at the "main entrance" near Villa Romana (as of June 9, 2025).

Magnificent views, bring water and suitable footwear. Follow the blue dots on the rocks if the path seems uncertain.

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.
