Cruising into the Bay of Naples is a memorable experience. The Naples port is overlooked by the imposing Sant Elmo medieval castle, high up on Vemero Hill, as well as the 13th century Castel Nuovo, which is right next to the Naples cruise terminal in the heart of the city. Within a short walk, to the left of the terminal, are three of Naples best-known landmarks: Castel Nuovo, the 17th century Royal Palace (Palazzo Reale), and the elaborate 18th century San Carlo Opera House. To reach Naples' fascinating old town, go straight past Castel Nuovo and then over the Piazza Municipio. The cities archaeological museum majors on Pompeii and Herculaneum, the two extraordinary sites that draw most first-time visitors to Naples. The city is also a convenient base for tours to the nearby swish cliff-top resort of Sorrento and the even swishier island of Capri.
