Set between Rome and Naples amid the so-called Ulysses Riviera, gorgeous Gaeta overlooks the beautiful Tyrrhenian Sea. Its history as a resort dates back to Imperial Rome. Nearby sites include the first-century BC mausoleum of general Lucius Munatius Plancus. Its old town is mostly medieval, showcased by narrow alleys, the massive 13th-century castle and the 12th-century Cathedral of Assunta e Sant'Erasmo. For relaxing, lovely and central Serapo Beach is a favored locale.

Just a few miles west of Naples (and easily reached by train), the ancient seaside city of Pozzuoli is probably best known for its bradyseism, a raising and lowering of the Earth’s surface due to underground volcanic activity. Many sites remain from Pozzuoli’s days as an important Roman port, including the Macellum or Temple of Serapis, which for many years was submerged under water. The Flavian Amphitheater (Italy’s third-largest) and the Cathedral of Rione Terra are other popular attractions.

Serving as the main port town for the island of the same name, the town of Ischia has been inhabited for centuries, famous for its beaches and the healing waters of its spas. The town is divided in two: Ischia Porto is the harbor district and commercial center of the island, filled with brightly lit taverns and bars, and Ischia Ponte, the historic quarter, with its ancient castle and its stone streets seemingly frozen in time.
