Neptune's  Grotto​

Latest update: 17 February 2022
Located just a short distance across the water from the seaside town of Alghero, Neptune's Grotto is a popular excursion where you can spend the day exploring the cave's fascinating stalactites and stalagmites. Tour guides are available in both English and Italian to show you around the cave and reveal its secrets. 

If you have a car it's possible to reach the site in around 35 minutes from Alghero, but by far the most popular way to get there is by boat. It takes around 45 minutes to make the short journey of 13 kilometres west of Alghero, with prices in the region of €15. If you want a little taster of what Neptune's Grotto is like, then watch the 1979 film Island of the Fishmen which was partially filmed there.
