Giglio Island, situated in front of the promontory of Argentario, from which it is separated by 16 km stretch of the sea, is formed by a granite mass covered with mediterranean vegetation alternating with large pine forests and numerous vineyards which enable the production of the famous "Ansonaco" wine. Giglio Island is 8,7 km long. Its total surface is 21,2km2. The coast, 27 km long, is made up of rocks, of smooth cliffs and suggestive bays: Arenella, Cannelle, Caldane and Campese, the biggest one with its little homonymous village.
The two other more important inhabited centres are Giglio Porto, the principal commercial centre with its characteristic mooring point, and Giglio Castello with its marvellous medieval village entirely surrounded by walls, which dominate the two sides of the Island. The principal attractions of the island are unspoilt nature, a mild mediterranean climate, and a clear and transparent sea, nowadays found in very few places. For these reasons Giglio Island is a perfect place for nature lovers, for a summer stay but also in the other sea-sons. Boats leave from Porto Santo Stefano to reach Giglio Island. From Easter to September there are 9-11 daily round trips and 6 during the winter season: the crossing takes 55 minutes.
