Neptune’s Cave

Plan your visit

Book your entrance only if you choose to reach the Cave by land, taking the Escala del Cabirol. If, on the other hand, you wish to access the Cave by sea, please note that booking is not required. The cost of the ticket for the boat trip does not include admission to the Grotto of Neptune. Click here for more information.

Booking a time slot does not include the purchase of the entrance ticket to Neptune’s Cave: you can buy your ticket directly at the Cave’s ticket office.

Choose Alghero Ticket, the single pass to discover Alghero, if in addition to the Neptune's Cave you also wish to visit the city's main attractions.

The guided tour starts every full hour and leaves from the entrance to Neptune's Cave, at sea level.

In order to ensure a safe visit, we ask you to be punctual. It is necessary to arrive at the square in front of the overland entrance to Neptune's Cave at Capo Caccia no later than 40 minutes before the start of the tour in order to accommodate the time necessary for the check-in and to descend the steps.
