For just $35, you get an immersive experience that’s both educational and visually stunning—perfect for a quick escape from the bustling streets of Naples or the nearby coastal towns.

The semi-submarine itself, called Nemo Sub, is Europe’s only vessel of its kind. Its large windows and external viewing platform give you different perspectives—inside, you’re in a bubble with views of statues, mosaics, and the Roman fish farms, while outside, you can snap photos of the coastline and harbor. This dual vantage point offers a well-rounded experience, especially for those who prefer not to be fully submerged or who want to stay in a safe, stable environment.

The journey begins with a brief safety and overview from your live guide, who speaks English, Italian, and Spanish, ensuring clear communication.

As the semi-submarine glides along the water, you’ll pass by key sights like the Nymphaeum of Claudius—an ancient Roman structure adorned with statues—and the Aragonenses Castle of Baia, a historic fortress that has watched over the bay for centuries.

The Experience from Inside and Outside

The large windows inside the Nemo Sub are a real highlight. They allow you to see the underwater world clearly, almost as if you’re floating in an aquarium. Plus, the vessel offers outdoor viewing spaces where you can stand and take photos—something many reviewers found to be a bonus, especially when sunlight hits the water just right.
