The Grotte di Nettuno is located on the top of a peninsula in the northwest of Sardinia. At the end of the road is a trail uphill to a lighthouse, which is located almost above the cave entrance. The entrance, in the middle of the vertical cliff is reached on a narrow footpath, which was cut into the soft limestone. The trail is called escala del cabirol (goat staircase) and was built in 1954. But the cave had been open to the public for a century before, it was visited by boat through the sea entrance.

The cave was discovered in the 18th century from the sea by a local fisherman. He was fishing off the peninsula, when he spottet an entrance in the cliff face. The entrance is above the water level and not easy to reach. Only during storms the seawater splashes into the cave entrance.

One of the highlights of this cave is the 120 m long cave lake. It is connected with the sea and contains salt water.

There is also a site named Frecce delle Grotte di Antonio Piccinnu

As there are basically two possibilities to visit the caves with three independent operators, it is a little difficult to book tickets. If you arrive by boat you can buy your cave tickets at the cave entrance, if you arrive by car you can buy the tickets for the staircase and the cave at the parking lot. There are people who only want to walk the staircase for the view and omit the cave tour. Additional problems are lots of visitors during the season and the corona pandemic restriction, which should be over by now. Nevertheless, you should either book the ticket for the staircase plus the ticket for the cave or the ticket for the boat trip plus the ticket for the cave online before you go. Boat tours are only possible if the weather conditions are good enough, and they are offered only between April and November.
