A boat ride from Alghero is the best way to visit Grotta di Nettuno, as it's quite a charming trip. Disembarking is especially entertaining, and a little nervewracking, depending on the state of the sea. Some seriously skilled ferry boat captains judge the swell of the sea just right to not dash you against the rocks. The caves themselves are... More

We visited the cave in January and I'm happy that we did that although we read that it is open from April - October... Nice challenge to take the more than 600 steps but worth doing it. Found it a bit expensive though.

We took a bicycle here from Alghero, which is quite a ride for untrained mortals like my girlfriend and I. The sights on the stairs are worth the trouble and once inside the cave it looks pretty cool with all the formations. Overall a nice daytrip, but wear comfortable and sturdy shoes.

I visited Neptunes Grotto with some work friends, and it was a great attraction to see because it was so different from the beaches and the ocean views that Sardinia provides many of. There is a steep climb down and back up with 600 odd stairs. It is fine on the way down, but it is good to take it... More

It's not the most spectacular cave I have seen but it's a nice quick boat ride from the jetty just before Capo Caccia. If you plan to drive to the jetty then make sure you get there early because there's no proper parking, just a rocky patch where the road ends which has a capacity of about 5 cars. I... More

Definitely worth a visit! The stalactites are really impressive. We took the boat from Alghero which was fun. Be aware if you are planning to use the steps down to the cave they are very steep.

Even after walking down and up all those steps, I would say it was worth it. The tour itself is very short, maybe 30 to 40 minutes, but the guide spoke in a number of different languages and he could be heard very easily with a good speaker system. Well worth a visit

I just checked and Merrian Webster defines "Tourist Trap" as : a place that attracts many tourists and that charges high prices. Well...this Grotto comes very, very close to the definition, in my opinion. The guided tour tells you "this cave is called the Christmas Tree, because the stalagmites look like... a Christmas tree!" Well, thank you for the information.... More
