Ponza like all the Pontine islands must be experience by a sailing vacation. At the arrival the isle shows itself with the semicircle of the rosy houses in the port, the Roman swimming pools and the fascinating sight of the tiny churchyard on the mountain. The tourist can go into the isle walking along some fascinating lanes till the isle's inland. He will find in front of him wide tracts of vegetation in bloom, above all brooms. On the whole, abundant fields also form the scenery. But the sea compensates all. The rocks of tufa, because of the wind and the frequent sea storms, have been modelled. The scenery shows a wide sequence of stacks, headlands, caves, bays, points, inlets and beaches, all of incomparable beauty.The seabed is rich of rocks and walls covered by various species of seaweeds. Also the rock's fauna, admirable with sub aqua excursions, is very rich.
The island is famed for its grotto, which were created by Etruscans. It has the Serpents Grotto and the Roman Gallery which is a Roman tunnel to connect the town of Ponza to the large beach called Chiaia di Luna on its west side. There are Egypitian, Cannanite, Greek, and Phoenician Necropoli ruins. It has a small town named Ponza and another one named Santa Maria and a few smaller towns. Ponza is often confused with nearby islands like Ischia and Capri, except Ponza has no active volcanism. The northernmost island of Zannone serves as a wildlife refuge for some flora that are no longer found elsewhere in the Mediterranean. It is part of the Circeo National Park.
