The grottoes of Ustica offer a natural sight, that is hardly reproduced in other places, involving all your senses: ancestral, uncontaminated and wild charms that originated thousands of years ago. Enchanted eyes will follow a profusion of reflections of light that creep in the grottoes and play as in a kaleidoscope of colors on the rocks. The ears will be astonished to the noise of the sea as it breaks in different ways on the volcanic rocks producing variable and alluring magic sounds.

Ustica's grottoes are all different and each one offers a special emotion by showing the geological history of the island: the Blue Grotto where the sea takes on an intense turquoise color; the Green Grotto with its emerald reflections; the Pastizza Grotto, which hides within other grottoes, some underwater others partly submerged; the Boat Grotto, where in the past fishermen would find shelter with stormy sea, and, at last, the Gold Grotto with glittering golden walls.
