Why visit the Neptune’s Caves in Alghero?

It’s a perfect experience to enjoy with the whole family in Alghero, and it will surely enrich your trip to Sardinia.
How to get to Neptune’s Caves
You have two options to reach the caves: by land or by sea. Both have their charm, so choose based on your time, budget, and the type of experience you’re looking for.
By land: the Escala del Cabirol
If you love to move and don’t mind a bit of effort, you can reach the caves on foot by descending the famous Escala del Cabirol (Roe Deer Staircase), a staircase of about 654 steps carved into the cliff overlooking the sea.
The view is spectacular, but the descent and ascent require some energy, so wear comfortable shoes and bring a bottle of water, especially if you visit in spring or summer. To reach the Capo Caccia parking area, where the staircase begins, you can:

Important: you must arrive at the parking area 40 minutes before your tour’s start time for check-in and the descent. If you’re late, you risk losing your reservation.

If you prefer a more relaxing experience, you can reach the caves by boat from Alghero’s port or the Cala Dragunara pier in Porto Conte. The trip takes about 40 minutes and lets you admire the Coral Riviera, with its cliffs and the Foradada Island.
Companies like Navisarda or Frecce delle Grotte offer regular trips. No reservation is needed for the boats, but the boat ticket (about €17 for adults) does not include the cave entrance fee, which is paid separately.

Practical tips for your visit
