Many passengers use Civitavecchia as a stepping stone to the ancient wonders of Rome, which are a mere hour or so away by train or road. But with its pretty piazzas, strollable seafront promenade, and bustling open-air markets, the historic fishing port is a destination unto itself. Highlights include the impressive 16th-century Forte Michelangelo, built to defend the harbor from pirate raids; the mineral-rich Ficoncella Thermal Baths, beloved by locals and visitors alike; and the beautiful Baroque architecture of Cattedrale di San Francesco and Santa Maria dell'Orazione. Don't leave without sampling the fresh, local seafood, preferably washed down with a glass of crisp Frascati.

In 2019, UNESCO warned the Italian government that Venice risked being added to the “World Heritage Sites in Danger” list due to the continuous damage caused by large ships to the city's fragile architecture and ecosystem. In response, the government designated Venice's waterways as national monuments—a status typically reserved for artworks and historical buildings—granting the lagoon enhanced state protection. The new regulations require ships longer than 590 feet to find alternative berthing locations. Fusina, a nearby industrial port adhering to maritime safety and environmental laws, emerged as the solution. Although the port is not as picturesque as Venice's Grand Canal, a scenic 30-minute boat ride from Fusina brings visitors to a central city pier, offering a perfect starting point to explore all of Venice's romantic, watery attractions.
