What to expect
It may be named after the Roman god of the sea – but Neptune's Grotto was discovered only a couple of hundred years ago. Hidden just above the water level at the base of the towering and remote Capo Caccia cliffs, the grotto is one of Sardinia's most dramatic natural attractions.After sailing from the harbour, you'll pass rugged coastline before reaching the grotto in under an hour. On arrival, you can choose whether to go in to Neptune's Grotto or not. If you do, you'll see stalactites biting down like incisors from the roof of the cave and stalagmites stabbing...

Very difficult to find the boat, because there was nothing signed as Antonio's Boats. The trip itself was lovely, other than the boat being so overcrowded that it was impossible to sit down.

Bateau très bien entretenu.
Pratique pour aller aux grottes et revenir.
La visite des grottes (payante en plus) nous a moins plu mais rien à voir avec le transport en bateau.

Overall a fantastic trip, the only downsides were that the tour of the caves felt rushed, and on the return journey we couldn't get a seat on the boat (im sure there were enough seats but other people spread themselves out and refused to move up) so we had to stand for the whole journey

We were not told that there were extra charges when we arrived. I had understood fee charge was inclusive of cave entry but this turned out not to be so doubling costs.

We really enjoyed our trip to Neptune’s Cave. The boat trip was great and the caves were magnificent. The only disappointment was we were told all over the internet that entry to the cave was €10 and when we got there we got charged €14, even though it said €10 on the board.
