Amazing place to visit and a very spectacular road to get there. It is " only " about 600 steps downhill to reach the cave entrance. The view which you see going down the rock is amazing. Amazing is also a sound of crashing waves. Cave itself is a breathtaking. Worth to go there, but remember - there are another... More

The Caves of Neptune, the karst formations are located approximately 24 km from Alghero, in the north-west of the promontory of Capo Caccia, homonymous protected area of north-west Sardinia. The cave was discovered by a local fisherman in the eighteenth century, and since then have proved a popular tourist attraction. The cave gets its name from the Roman god of... More

Couldn't go because the stairway walk there was under repairs in March Didn't see any info about boat trips so suspect they are also not running until the summer.

The boat ride to the grotto was nice. You pay on land for the trip. Once at the sight, they wanted an additional €16.00/person to go into the grotto!!! We were mad and walked up the outside steps along the wall to the top of the mountain. The views are spectacular! And worth the trek. Another part of our party... More

It was terrific, scaring, exciting and beautiful altogether!!!. I refer to the boat trip to the cave. the cave itself it is not impressive but the arrival is something not to miss. Careful if you have health problems because the arrival is not easy. the crew do their best to put the bridge between the boat and the cave but... More

Great sight to see, just driving to it and you see spectacular views. Parking is easy on the strip to entrance. We walked down/up the 600 odd stairs and down is easy but omg going up is def hard! We are fairly fit and it is a struggle but an experience just in itself. The caves are also beautiful and... More

The cave itself is really nice (directly accessible by land or by sea) but the real spectacle is outside it. The stairs that lead to it provide you with a jaw-dropping scenery, it's truly breathtaking. The water has a deep blue, vibrant color that I've not seen anywhere else. My vacation photos look like they've been Photoshopped, it's that beautiful.... More

Enjoyed the experience as not been in caves for many years but don't expect any wow moments beyond the first 2 minutes inside. Tour is longer then you need as guide as to say everything in 3 languages. We parked at cliff top and walked down - hard work even if fit. But the views and reward makes it worthwhile.... More
