If you’re visiting the Naples area and love a mix of history, beautiful scenery, and a touch of adventure, the Submerged Park of Baia Glass Bottom Boat Tour is worth considering. This one-hour experience offers a unique window into ancient Roman life beneath the waves, without getting your feet wet—unless you want to snorkel later, of course.
What makes this tour stand out? First, you’ll get close-up views of the spectacular mosaics of Baia’s submerged archaeological park. Second, the presence of knowledgeable guides, including archaeologists and naturalists, means you’ll learn plenty while soaking up the scenery. Lastly, the views of Monte Nuovo and the Aragonese Castle from the water give you a fresh perspective on this historic and scenic coastline.
A potential drawback? The duration is quite short for those wanting an in-depth exploration, but for many, that’s part of the appeal—an efficient way to see a lot in a brief sit.

Exploring the Baia Submerged Park from Bacoli

One of the most compelling aspects of this tour is the chance to see the ancient Roman villas and baths that now rest beneath the water’s surface. The guide will introduce you to sites like the Terme del Lacus and Villa a Protiro, with a diver swimming under the boat to showcase mosaics that are still remarkably intact.
We loved the way the guides described the mosaics and historical context, making the experience both educational and visually captivating. As one reviewer put it, “Antonio was very knowledgeable about the history and artifacts,” making the 60-minute trip feel like a personal history lesson delivered with enthusiasm.
The diver’s role adds a special touch—floating beneath the boat to keep the mosaics clear of sand or debris, which enhances the viewing experience. Watching the diver wave and smile through the glass provides a fun, lighter moment amid the historical awe.
