If you’re exploring Crete and looking for a way to enjoy its coastal beauty without getting wet, the Semi-Submarine Boat Underwater Experience in Chania might catch your eye. This tour offers an unusual chance to see marine life through glass windows while cruising comfortably in a small vessel. It’s a quick, family-friendly activity that combines scenic views, underwater sights, and a bit of local history—all in just about 35 minutes.
What we particularly like about this experience is how accessible it is; no need to be an avid diver or swimmer to enjoy marine life. Plus, the panoramic views from the upper deck give you a beautiful perspective of the Venetian Harbor and the White Mountains nearby. That said, it’s worth noting that the entire adventure is quite short, so if you’re after a more in-depth underwater exploration, this might feel a bit limited.
One consideration to keep in mind is the chance of seeing larger marine creatures like sea turtles—while they do appear in a majority of tours, it’s not guaranteed. If spotting marine animals is a key part of your trip, you might need a bit of luck on your side. But overall, this tour is well-suited for those who want a quick, safe, and informative glimpse of the sea without too much fuss or expense.
It’s especially good if you’re traveling with kids or if you simply want a relaxing way to enjoy the coast from both the water and the land. Whether you’re on a tight schedule, traveling with family, or just curious about the underwater world, this experience offers a practical taste of Crete’s marine environment.

What the Tour Looks Like
The core of this experience is the approximate 25-minute ride inside the old port and the surrounding waters, where you’ll peer through the glass bottom and see marine animals, such as fish and loggerhead turtles (though sightings of these turtles aren’t guaranteed). The boat then spends about 10 minutes outside the harbor, giving a chance for some panoramic shots of the Venetian structures and the coast.
The upstairs deck is a highlight, offering sweeping views of Chania’s old port, with its historic Venetian buildings, lighthouse, and bustling harbor life. It’s a good spot to take photos or just soak in the scenery while the boat gently moves along.
What to Expect During the Tour
Once onboard, you’ll be given an audio narration in Greek, English, and Russian. This commentary enhances the experience, providing insights into the marine environment and some local history. Many reviews appreciate the guides’ knowledge—“The tour was also accompanied with an insightful audio, providing information about local history and marine life,” one traveler mentioned.
Marine life sightings are a highlight, but as some reviews note, they do depend on luck. For instance, one traveler was fortunate enough to see a turtle, and the guide maneuvered the boat to give them a clear, close-up view. Others found the fish and bottom feeders interesting, even if larger creatures were scarce.
The Experience’s Pacing and Comfort
The interior area is described as clean with a fan to keep cool, which is important given Greece’s warm climate. The seating is comfortable, and the boat’s design allows you to stay dry and safe, even if you’re not comfortable in open water.
More Great Tours NearbyCost and Value
At around $20.33 per person, this tour is quite budget-friendly, especially considering it includes an audio guide and a chance to see underwater life up close. It’s not a full-day adventure, but for a quick, fun snapshot of the marine environment, it’s a reasonable price.
Who Will Love This Tour?
This activity is ideal for families, travelers with limited time, or those who prefer a relaxed, safe viewing experience. If you’re fascinated by marine life or photography, you’ll appreciate the views and the chance to capture some memorable shots. However, if you’re seeking an in-depth or longer underwater adventure, you might find this tour a bit too brief.
Real Travelers’ Perspectives

Several reviewers mention how much they enjoyed the experience. One said, “We were with two small kids, and it was an excellent experience, nice views of fishes and a giant turtle,” highlighting its family-friendly nature. Another noted that “The experience itself was incredible, in the submarine bottom you are presented with a clear view of the Marine life beneath you,” emphasizing how engaging it can be, especially when wildlife appears.
However, some reviews advise managing expectations—“You need luck to see some nice or special things,” as marine sightings can vary. Still, the guides’ efforts, like feeding fish to attract them, add to the fun, especially for kids.
Practical Tips for the Tour

- Book early if you want to go at a less busy time, like the 11 am slot, as some travelers found it to be quieter and more personal.
- Bring sunscreen and a hat, since you’ll be outside on the deck and in the harbor area.
- Consider seasickness medication if you’re prone to seasickness; the ride is generally calm, but a heads-up is always wise.
- Check the weather forecast before booking—bad weather could lead to a shorter or modified tour, possibly only inside the harbor for safety.
Final Thoughts: Is This Tour Worth It?

For just over $20, you get a unique perspective on Crete’s underwater life without the need for diving gear or swimming skills. It provides a quick, scenic, and family-friendly way to explore the coast. The panoramic views of Chania from the water are beautiful, and the chance to see marine creatures, even if just fish, adds a fun element.
While the short duration and dependence on luck for animal sightings might leave some wanting more, the overall value for the price is solid. The friendly guides and clean vessel make it a comfortable experience, especially for those traveling with children or seeking a relaxed activity between more intense sightseeing.
If you’re curious about marine life and enjoy scenic boat rides, this semi-submarine experience can be a charming addition to your Crete itinerary. Just be mindful that it’s more about the quick glimpse than an in-depth adventure, and plan your expectations accordingly.
