The Pontine Islands are a pretty archipelago off the Italian coast toward the South of Rome, with a long history, attested by Roman ruins and Rupestrian tombs.
There are only two islands, Ponza and Ventotene, large enough to offer accommodation possibilities and regular ferry connections. The other islands of the Pontine Archipelago, including the Zannone nature reserve, can be visited on boat trips from the two largest islands.
Palmarola a small island opposite Ponza and almost uninhabited. There is a small mooring place for boats and a restaurant (only in the summer). The Green Island of Zannone is a nature reserve, and also the site of a ruined monastery, built in 1213.
