A stunning volcanic archipelago just off the coast of Lazio, the Pontine islands offer you turquoise waters, tiny vineyards, wild herbs and flowers. In the summer it can be pretty crowded with Italians flocking in from Rome but foreigners are still some sort of a rarity.
Ponza is the most interesting island. It’s full of grottoes and secluded beaches. The Pilatus Caves are one of the main highlights and most visitors take one or more boat trips.
Ventotene is smaller and more tranquil. For most of its history it was a prison and there’s not a lot to see and do now. There are remains of a Roman villa – but they’re not exactly spectacular. The beaches are okay but the tranquility of the island is probably the main draw.
