Discover the underwater world of Crete from a semi-submarine boat in Chania. Enjoy panoramic views, marine life sightings, and an engaging experience for all ages.
If you’re visiting Crete and looking for a way to see marine life without getting your feet wet, the Semi-Submarine Boat Underwater Experience in Chania might catch your eye. This tour offers a 35-minute journey aboard a modern semi-submersible vessel, providing a unique glimpse into the sea bottom, marine creatures, and the stunning coastlines of the old port and White Mountains. It’s a compact but engaging activity that combines sea exploration with beautiful vistas of Chania’s historic harbor.
What we really like about this experience is the combination of underwater viewing and panoramic sea views. The large glass windows in the boat’s lower deck allow for a safe, dry, and comfortable way to observe fish, turtles, and other marine life. Plus, the chance to go upstairs and take in the scenic views of the Venetian harbor and coast adds a special touch. On the downside, the experience’s short duration and dependence on weather conditions might mean it’s more suitable for those with limited time or families with young children.
This activity works well for travelers seeking a family-friendly, value-packed outing or anyone curious about marine environments who prefers a relaxed, guided experience. It’s especially appealing if you want a safe, accessible way to see underwater life and enjoy spectacular coastal vistas without the commitment of a full-day boat trip.

The tour begins at the Old Venetian Port of Chania, specifically near the Neoria houses. The meeting is straightforward, and the procedure is smooth — no need to worry about long lines, as skip-the-line options are available, and you can reserve your spot in advance. The vessel is a 10-meter semi-submersible, designed for up to 12 passengers plus the crew. This relatively small size means you’re likely to enjoy a more intimate, less crowded experience.
Once aboard, you’ll quickly notice the modern design of the semi-submarine, which allows you to view the underwater life through large glass windows in the bottom section. During the 25-minute journey around the old port, you’ll be treated to sights of bottom feeders and a variety of fish.
One of the most frequently mentioned highlights by guests like Robyn is the opportunity to see a loggerhead sea turtle, although sightings depend largely on luck. The guide is known to spot turtles and maneuver the boat for a clear view, making this a memorable moment. As Robyn notes, “We were lucky enough to see a turtle, which the guide spotted and manoeuvred the boat around so we could watch it.” Many reviewers appreciated the clean, comfortable downstairs area, which was cooled with a fan — a bonus on hot days.
After spending time below, you can head upstairs on the deck to take in the panoramic vistas of Chania’s old harbor with its Venetian architecture and the White Mountains in the background. It’s a great spot for photos or simply soaking in the fresh air. Joanna mentioned that perhaps the tour could be more engaging with more “live” guidance or detailed descriptions of marine life, which suggests that while the audio guides are helpful, a more interactive or descriptive commentary could elevate the experience.
The tour includes a 30-minute circuit: roughly 25 minutes exploring the old port and a further 10 outside it, ending near the rocky wave thruster. The boat pauses at scenic spots where you can take photos of the town from the sea, making it a good choice for those wanting some memorable coastal shots or a relaxed sightseeing cruise.
The ticket includes the semi-submarine ride and an audio narration in three languages, making the experience accessible for most visitors. However, soft drinks or water are not provided, so consider bringing your own. Also, note that there is no pickup service, so you’ll need to get to the meeting point yourself.

Many travelers found the experience to be excellent value for money, especially with the chance to see marine life close-up without hassle. Ildikó shared that her family, including small kids, enjoyed the views of fishes and a giant turtle, despite only viewing from inside the harbor. Robyn’s account highlights the personalized experience of having the whole boat to themselves during an early-morning trip, which she highly recommends for a more private and relaxed outing.
Others, like Joanna, expressed a desire for more detailed guides that could describe fish species or artifacts they might encounter, pointing to a potential area for improvement in the audio narration. But overall, the tour’s informative guides and scenic stops made it a worthwhile outing.

This semi-submarine experience is ideal for families, especially those traveling with young children who want a safe, dry, and engaging way to see marine life. It’s also perfect for visitors with limited time who want a quick, scenic activity that combines sightseeing and marine exploration at a reasonable price.
If you’re a solo traveler or couple looking for a more in-depth or adventurous marine experience, you might find this tour somewhat limited. The short duration and focus on the shallow coast mean it’s not a substitute for full-day snorkeling or diving trips, but it’s a nice, hassle-free option for a relaxed afternoon.

The Chania Semi-Submarine Underwater Experience offers a friendly, accessible window into Crete’s marine environment. With its modern design, panoramic views, and the chance to see a turtle or fish without getting wet, it provides a memorable, family-friendly outing. The tour’s affordable price point makes it especially attractive for budget-conscious travelers who want a taste of underwater life with minimal fuss.
While it might not satisfy those seeking detailed marine guides or longer excursions, its blend of scenic beauty, marine sighting opportunities, and ease of access makes it well worth considering. If you’re in Chania and eager to see the sea beneath the surface, this activity delivers on its promise of a safe, enjoyable glimpse into underwater Crete.
