Take any boat trip, the stairs are too much to bear. I took the stairs and done 554 steps on the way down. Visited the place and realised that I could not climb the up again. So took a boat back to Alghero.

Semi-expensive (like 15 euros) for a 40 min cave tour. Interesting caves with some impressive geological phenomena.

If you are in a good condition you can take the bus from Alghero for 2,50 €. Then you have to run down a few hundred stairs just to cathc hourly guided tour. After the visit you have to go up the stairs and if you are fast enough you can even enjoy a latte macchiato or a glass of... More

Massive caves, nothing like Cheddar Gorge caves in UK. Gets very busy with boat tours etc; Only allow visitors in every hour. No photos allowed but everyone was taking them. There are 600plus steps down to the cave if you don't take a boat trip. Admission is well worth the money.

These caves are at the end of a beautiful walk along the sea, I had never seen a Stalactite cave before, so it was a unique experience looking at the marvel of nature, admiring the beautiful natural formations. The salt lake adds to the beauty of this place- there are few spots where you would not be able to differentiate... More

We enjoyed our visit via a very pleasant boat trip from Alghero. It is a extensive set of caves, with beautiful and impressive structures and glad we went. What spoiled it, was that it looks as if a lot of damage had occurred either over the years before it became a tourist attraction or as a result of turning into... More

Neptune Grotto is awesome! from the top there is a gorgeous view of the ocean even though the hike all the way down is a bit challenging especially heading back. It is a good hike up but over all the grotto is amazing. It is a must see.

Worth to see, but don't get intimidated by the number of stairs (by boat trip providers; unless you have severe health problems or respectable age). It is the best part of the way to climb the stairs over the sea (and it s not a problem to do it with small children).

Legendary caves that can be visited either on foot or by boat. There are 600 stairs down, 500 inside and then 600 up again - in scorching heat, this is really for the young and fit. There are no facilities inside the caves, so make sure to take plenty of water with you and to deal with all sanitary requirements... More

We rode the bus out to Capo Caccia. It was easy and only about 25 minutes. We hiked down to the caves. The view on the hike is unbelievable. Really incredible and a super fun hike. I did it with my four kids aged 8 to 17. They all made it easily. The hike back up got a little sweat... More
