Fodor's Expert Review Grotta di Nettuno

At the base of a sheer cliff, the pounding sea has carved an entrance to a vast fantastic cavern filled with stunning water pools, stalactites, and stalagmites. The dramatic cave and coves, discovered by fishermen in the 18th century, are popular tourist attractions for their sheer natural beauty. You must visit with a guide; tours start on the hour. It's possible to reach the caves by boat or by land. Between April and October, boat trips depart regularly from the port of Alghero for €16 round-trip (admission to the grotto is extra). To reach the grotto by land, you can descend the 654 dizzying steps of Escala del Cabirol ("Goat Steps"), which are cut into the steep cliff here.  By public bus from Alghero's Via Catalogna, the trip to the top of the stairway takes about 50 minutes. Allow 15 minutes for the descent by foot. Visitors arriving by land must book beforehand by telephone or online at  www.algheroexperience.it.
