Ustica Caves offer a natural spectacle that is difficult to repeat in other places and that involves all the senses: ancestral, uncontaminated and wild charm that tells of millenary spaces. The eyes will be enchanted by the thousand reflections of the light that creeps into the inlets of the caves and is reflected as in a kaleidoscope of colors on the rocks. The ears will be amazed by the sounds of the sea breaking with different voices against the volcanic rock walls, producing variable and fascinating acoustic suggestions. Caves are scattered along the entire perimeter of the island, in all areas of the Ustica Island Protected Marine Area.
