Neptune’s cave is placed in the calcareous promontory of Capo Caccia, on the coast-side more exposed to the sea strength and erosion. A real gift of earth, a rare and wonderful place where you can discover its geological characteristics. Not far from Alghero, it can be reached by boat-ferry or by land also with

 guided tours. Every year over 150 thousand visitors, coming from all over the world, visit the cave and its fascinating surroundings characterised by its enormous concretions and its small limpid internal lakes. Many chambers, tunnels and wells are spread over 2500 squared metres, making it more complex and intricate. It’s called the "Naturalistic Pearl of the Mediterranean sea" for its natural rare characteristics.
