If you’re visiting Corsica and looking for a way to explore its stunning marine environment without getting your feet wet, this semi-submarine tour in Porto is worth considering. While it’s short—just 45 minutes—it offers a gentle, accessible way to see the underwater world, especially if you’re not keen on snorkeling or diving.
What we really like about this experience is how it combines easy access to marine life with a chance to learn about the region’s natural beauty. The guided commentary, available in multiple languages, helps you understand what you’re seeing and why it matters.

The Marine Environment
Once underway, you’ll get the chance to look down into the water through large viewing ports built into the boat. These are designed to give a clear view of the seabed, showcasing the local flora and fauna—think small fish, seaweeds, and perhaps some crabs. According to reviews, the experience can vary; some visitors mention the fish are plentiful, especially when the captain feeds them, while others note that the water might not always be teeming with life.
Many reviewers, like one who called it “a very good activity to do as a couple or with family,” appreciated the opportunity to see marine life in a relaxed environment. Another mentioned that “everything was perfect,” highlighting the peaceful ambiance and the space to enjoy the surroundings.
Highlights of the Regional Area
While the main focus is on the underwater world, the tour also offers some insight into Porto’s history and geography. You’ll learn about the Calanche, the striking red cliffs that are part of the natural reserve of Castagna, and see the Porto Tower, a famous landmark that plays a role in the region’s maritime history.
The Experience Itself

The ride lasts just 45 minutes, making it a quick but delightful interlude during your day. The semi-submarine design means you don’t have to get wet or uncomfortable to enjoy the views. The large viewing ports provide a clear, uninterrupted view of marine life (or the lack thereof, at times), which is great for kids and adults alike.
One aspect that many travelers appreciate is the quietness and space aboard the boat. Dennis, a traveler from Belgium, shared that “we were alone on the boat, so we could enjoy the space and silence even more,” which is a nice bonus if you’re seeking a peaceful, less crowded outing.
