The island was joined with the Sorrentina peninsula; later it was submerged by the sea and consequently separated, creating the Straits of Bocca Piccola. Its land is a mix of mountain, hills and highlands. The most important is Anacapri, but the other areas are Marina Grande on one side and Marina Piccola on the other side.
The coast has a lot of caves. One of the most famous is the “Grotta Azzurra” built during Roman Empire.
The Faraglioni are a kind of small stone islands not far from the coast that create a particular effect.
