What Travellers Say
Reviews Summary
Grotte di Nettuno is a stunning natural wonder with impressive stalactites and stalagmites, offering a memorable experience whether you descend via the scenic 900+ steps or arrive by boat. Visitors are captivated by the cave's beauty, particularly the underground lake. However, some find the experience marred by a lack of crowd control and maintenance, with concerns raised about rule enforcement and the preservation of this natural treasure.
"Amazing experience huge cave. Good boat trip. Need to reserve unless you go by boat."
Natalia Uribe
"Even though it was beautiful sunny day, they closed the Cave because of 'severe western conditions"... everybody was pretty shocked."

"Although the cave is truly impressive and beautiful and definitely worth visiting, it’s a shame how poorly it’s maintained. There’s almost no crowd control, they even allow dogs inside, and the staff doesn’t enforce basic rules such as no flash photography. Some visitors were touching the stalactites and stalagmites without any supervision. All of this makes the experience much less enjoyable and puts this natural wonder at risk. It really deserves better protection and management."

Navigating to Neptune's Cave: Steps vs. Sea
Alternatively, boat tours provide a more relaxed and accessible route. Departures are common from Alghero and the nearby Cala Dragunara pier in Porto Conte Park. These tours offer a different perspective of the dramatic cliffs from the sea and are ideal for families, those with mobility concerns, or anyone who prefers to conserve their energy for exploring the cave's interior. It's wise to book boat tickets in advance, especially during the busy summer months.
Inside the Grotto: A Natural Wonder
One of the most captivating features is the underground lake, whose still waters often reflect the dramatic formations above, creating a surreal and beautiful scene. While photography is permitted, flash is strictly forbidden to protect the cave's ecosystem and the formations themselves. Despite the natural beauty, some visitors have noted issues with crowd control and adherence to rules, highlighting the importance of respecting the environment and the guidance of the tour operators.
Practicalities: Cash, Closures, and Considerations
Another crucial factor is the weather. The cave's access, especially via the steps and the boat tours, is highly dependent on sea conditions. Even on a sunny day, strong western winds can lead to unexpected closures. It's advisable to check local forecasts or inquire with tour operators before setting out. Some reviews also mention that the cave's maintenance and management could be improved, with occasional issues regarding crowd control and rule enforcement. Being prepared for these aspects will help ensure a smoother and more enjoyable experience.
