Marettimo is the second largest island in the archipelago and the farthest from Sicily. It is separated from Marsala by 20 miles of sea, 13.5 miles from Favignana and 70 miles from Cape Bon (Tunisia). Marettimo is the oldest island of the Egadi Islands. It is described as a natural botanical garden, in fact the island is an imposing mountain full of plants and paths. But it is in the sea around Marettimo that the island offers its best: a paradise for snorkelers and those who love to discover caves, in fact Marettimo is the island of caves.
Sailing north you reach a strange rock that is shaped like a camel; inside is the Cave of the Camel. Following the path you will reach Cala Mione, a shelter when the sea becomes dangerous, and the Grotta del Tuono (Thunder Cave), so called because of the loud noises that can be heard inside, caused by the water. Crossing P.ta Due Frati you will come across a magnificent cleft in the rock: this is a green marble cave, and in addition there are Grotta Berciata, Grotta Bombarda and Grotta del Presepio, the latter with stalagmites, stalactites and statues inside.
