Grotte di Nettuno is an attraction in Alghero, Sardinia (Italy).
You can arrive by land following the road to Capo Caccia and descending the Escala del Cabirol, or by embarking on a boat tour from the port of Alghero. Boat departures are commonly used during the season and allow you to see the cliffs from the sea.
Visits are organized and generally have scheduled access; in high season, it's advisable to book or inquire about times to avoid long waits. Some boat excursions offer a transfer plus included guide ticket.
Many children may enjoy the visit, but you should consider the descent of the stairs (654 steps) and movement inside the cave. It is important for children to be supervised and not to run on the damp surfaces.
Yes, there are rest areas and parking near the Capo Caccia viewpoint, but spots may be limited, especially in high season. It's advisable to arrive early or consider the boat option from Alghero.
The duration of the guided visit inside is limited and varies depending on the route and organization; typically, visits last from a fraction of an hour up to an hour. It's best to check the official times for the exact duration of the tour.
