Giannutri is the southernmost island of the archipelago. Of volcanic origin and only 3 squared metres in size, it offers just 2 mooring places: Cala Maestra for motor boats and Cala Spalmatoio for the others. Those are active only on summer and have no water, electricity, fuel or toilets facilities.

In Cala Spalmatoio there is a small jetty for temporary mooring, a minimarket and a bar nearby. In the external side of the 2 corridors for boats access, parking, anchoring, fishing and diving are not allowed (the entire island is under video surveillance).

Here, Nature takes over, the typical Mediterranean flora intertwines with the ruins of the ancient Roman villa and the few existing houses.

The sea is characterised by pristine seabed where seahorses and starfish, various species of fish, dolphins and minke whales often swim. Near the island are some wrecks of merchant ships dating back of the period between the 3rd and 1st century BC. After the splendours or Roman time, it remained uninhabited for a long time and later became a Pirates’ hideout until the Napoleonic Era when it was converted to a defensive military settlement. It is now part of municipality of the Giglio island.
