1. The Blue Grotto is to all intents and purposes a museum and to access it, it is essential to purchase a ticket.
The blue coloration, from which the cave takes its name, is spectacular and is due to a particular phenomenon: the underwater threshold, blocks the red colors filtering only the blue ones.
The result is something wonderful and unforgettable.
The cave is composed of various parts:
– The blue dome, the marine cavity made blue by the reflected light.
– The landing, the artificial esplanade made in Roman times.
– The gallery of the pillars, a raised cavity divided into three branches by rock columns
– The hall of names, a vast cavity on the walls of which there are numerous names engraved by visitors,
– The passage of corrosion, an obscure corridor difficult to pass through.
– The Hall of Corrosion, the last accessible part of the Cave.
2. Cave of the Saints. Here it is the turn of the Saints, represented by the row of rocks whose tops are ovalised by the sea and may in fact recall the image of a procession of religious people.
3. Green Cave. Also known as the Cave of the Turks. Known since the sixteenth century, its distinctive feature is the peculiar emerald green color of the sea that is reflected on the inside walls especcialy after noon.
4.White Cave. It is about thirty meters long and its interior houses two small brackish lakes.
On its walls of white tuff are grooves and traces left by man since the seventeenth century, when the cave was a refuge against pirate raids.
5. La Meravigliosa. The well-deserved name comes from its gothic cathedral shape and the presence of stalactites and stalagmites that arouse immediate amazement. The wonderful cave can be reached, after landing on a tiny pier, thanks to a staircase built along the rocky wall to a short path that leads to an artificial tunnel that finally gives access to the fairy-tale cave.
6. Sea Ox Cave. It is so called because of the oral tradition of sailors. There are two hypotheses about the derivation of the name: the first, determined by the presence of a family of seals monks, the second may refer to the unique effect that the waves cause entering the cave compressing the air that generates a sound similar to that of a loud bellow!
7. Albergo dei Marinai. It closes with a cave that was used as a shelter by fishermen during storms. It has a double opening, one to the west, about 9 meters wide and a narrower one to the east… very impressive to swim in.
