By sea

The easiest way to visit Neptune’s Cave by sea is to take one of the boat trips that leave from the Alghero’s harbour on a regular basis or from the pier of of Cala Dragunara in Porto Conte Park. This is by far the best method of visiting for anyone with children or elderly people.

The journey by boat takes about 40 minutes. Visitors can admire the scenery of the Coral Riviera www.museialghero.itas the boat passes close to the Cape Galera and Punta Giglio cliffs and then rounds the tip of Capo Caccia to arrive right at the entrance to the caves which lie at the foot of a towering cliff – an impressive sight set against the backdrop of the small island of Foradada.

Not only do you avoid the steps down the cliffs, but the journey is thoroughly enjoyable and affords you excellent views of the cliffs as you approach.
