Only accessible by steps due to wind, but worthwhile

It was rather windy during our stay in Alghero and the boats were unable to visit the grotto throughout. One day at least the weather was so poor that the staircase to the grotto... read more

It was rather windy during our stay in Alghero and the boats were unable to visit the grotto throughout. One day at least the weather was so poor that the staircase to the grotto was also closed. Fortunately on our last day it was open. There really are about 640 steps to descend but they are well engineered and we... More

A lovely trip by boat the sea was a bit choppy.getting off the boat into the caves was a bit tricky but worth seeing even if you had to pay 13 euros each to enter the caves.

We got the boat over which was amazing, getting off the boat was fun as they could only get in so close but it was part of the adventure! You have to pay again to get s tour of the cave which isn't clear until you get there and you need cash. The inside of the cave was pretty impressive,... More

During our 2 week visit to Alghero, we rented a car for 3 days and visited Capo Caccia and Porto Conte areas during one of those days. It's a wonderful, easy drive to CC. We parked along the road, close to the bus parking point. The stairs to the grotto di nettuno begin at the bus parking area. Down, down... More

Nice trip but you pay for trip on boat, then pay again to see cave. Could benefit from explanatory booklet.

Just a tip but if you are traveling off-season, be sure to check the Office of Tourism whether or not this sight is open to public. The drive up to the Caves is beautifull nonetheless but to avoid dissapointment, better be save than sorry ;)

We only managed to see this wonderful sight because we're persistent and we lucked out on the third try. First we met a Dutch couple in a bar. They invited us to a drive the next day but cos it was raining the night it was closed (654 steps). The next day we went on a boat trip which normally... More

The busses arrive and leave on the hour (11, 12, 13 etc) and the tour of the caves start at the same time. This is problematic because it takes at least 15 minutes to walk to where the tours start. Since the tour is at least 40 minutes probably longer, this makes it difficult to go see the caves and... More

I wish I could have that time back in my life that was wasted going to this incredibly boring site. If you have not been to a cave with stalactites then I could see this having a definite appeal. However, the 13€ entrance fee is way too high for the value you receive in return. We arrived in off season... More
