    Beautiful but chaotic
    The cave is marvellous ! Stunning, breathtaking! But the organisation is chaotic as the boat trip is not adjusted to the sale of the entrance ticket of the cave. We had to queue for quite a while to get our ticket. Boat groups are mixed during the visit, we had to run for our boat. According to the guide it is impossible to streamline/combine sales of boat ticket and cave ticket. And this in 2023…Best book tickets for the cave online after you reserved the boat trip.

    Beautiful cave system but be aware of the possible dangers
    Neptune's grotte is a beautiful cave system at Cape Caccia on Sardinia.  There are 2 ways of accessing it either on foot following a very steep and long footpath from the clifftop to sea level or by excursion boat from Alghero. I don't like to write negative reviews but both methods have downsides. The boat is expensive because they don't tell you when you buy your boat ticket that you  will have to pay an entrance fee of 14 euros when you arrive at the cave. The walk is long 2.5k and involves descending a large number of steps 600+ and the same distance to return, so you need to be fairly fit. The tour of the caves is guided with commentary in Italian and English however it is very difficult to hear as the caves have a very strong echo and people have tendency to talk over the language which does not apply to them. The steps within the cave are steep and uneven. There appears to be no emergency equipment or exit or evacuation plan, and should the lights fail, the possibility of a mass panic is likely, resulting injury or worse. There is no ventilation, and the air is warm and moist an ideal breeding ground for diseases. We enjoyed the boat trip and the caves were very beautiful but if we had known the full facts we may have just taken a boat trip to see the coast.

    Beautiful
    We went by boat that is on the port in front of the entrance to the walls, name of the boat was Deborah, totally recommend we paid 16euros, is about 35 to 40 min to reach the place,the staff crew were amazing. They serve food and beverages at a reasonable price and they care about the clients. When you enter in the cave you need to pay another 16euros for the tour. We went at 10.45am what was good, not many people was inside so we had time to see and listen to our guide. The tour is about 20min more or less. Is really beautiful to see how nature works, the colour's reflecting in the water and on the stalactites were amazing. Tottaly recomend

    Make a time slot reservation
    Magical caves! Although I 100% recommend to reserve your time slot for the visit before you come there! We waited for almost 3 hours hoping they will have empty spots for us to enter the caves. After we found out that if you go by boat (no stairs to climb - although the views are beautiful), you don’t need a time slot reservation.

    Nice boat trip to the caves, good value. Pay separately into cave from boat
    Enjoyed our boat trip, and the caves were nice and easy to walk along. 2 hrs long. Well lit up. Once you come off boat you have to pay separately for entrance to cave which is time consuming and unnecessary.

    Evocative
    We were here last August with my family. The walk down and up the steps was quite challenging for me I have to say! The views are incredible, you can literally see the edge of the island. The grotto itself is quite a small inlet, but I'd say it's a quite underrated place. A bit on the expensive side though.

Before posting, each Tripadvisor review goes through an automated tracking system, which collects information, answering the following questions: how, what, where and when. If the system detects something that potentially contradicts our community guidelines, the review is not published.
When the system detects a problem, a review may be automatically rejected, sent to the reviewer for validation, or manually reviewed by our team of content specialists, who work 24/7 to maintain the quality of the reviews on our site.
Our team checks each review posted on the site disputed by our community as not meeting our community guidelines.

Lovely scooter ride from Alghero to the caves - the day before we went by boat to there, but did not enter. Spectacular view from the stairs down to the caves - 650 steps - downstairs is doable, up - better to rest from time to time :)
In the caves there is a guide tour each hour in Italian and English. It takes about 45 min to do the tour, enough time to look around and take lovely pics.
Bare in mind if you go by car that there is a lot of traffic and can be that you need to wait a lot to reach/leave the place to enter.

After an enjoyable boat trip from Alghero, the boat captain refused to land the boat to enable us to visit the caves, stating that there was a large number of young children (very badly behaved and completely uncontrolled) and that it would be dangerous for them to disembark.
It was obvious what these brats were like from the outset; he should have forbidden them and their teachers to board.
A complete waste of money.
The only joy was knowing that it is not only English kids can be a disgrace.
