Stop 1: Mirabello Bay – Underwater Sights & Marine Life
The highlight here is the semi-submersible vessel itself, which allows you to peer down into the sea through large viewing windows. It’s a clever way to see marine life without snorkels or diving gear. Expect to see fish swimming close by, and many reviewers have spotted sea turtles. The audio commentary enriches this part, giving background info on the marine ecosystem and diving conditions.
Some travelers, like Connor, appreciated this part: “Had an amazing trip, staff was very friendly and helpful. It’s a shame the views are much better on one side of each hull. We got lucky and got the better side and was great. My 22-month-old loved it.” This indicates that while the experience can be magical, the viewing angle makes a difference. Seating arrangements are assigned, but if you prefer the best views, try to sit on the outside when possible.
Stop 2: Agios Nikolaos Coast – Scenic Views & Coastal Landmarks
Once the underwater segment concludes, the vessel moves toward the coast, taking you past Agios Nikolaos and the surrounding luxury hotels. This is a more relaxed, panoramic part of the trip, lasting about 30 minutes. You’ll enjoy views of the town and coastline from the deck, perfect for snapping photos and soaking in the scenery. Many reviews mention that this part is peaceful and provides a good chance to see the coast from the water, with some saying it’s “very pleasant.”
YochevedE_C pointed out that “even though the underwater section was cramped, seeing a variety of fish made it worthwhile.” The second half is more about enjoying the scenery, and some travelers feel it’s a nice complement to the underwater viewing.
The Experience in Practice
The tour is priced at just under $20 per person, which offers decent value considering the marine sights and scenic views. It’s a brief trip—about 85 minutes in total—so it’s suitable if you’re tight on time but still want a taste of the sea.
The boarding process might cause some initial confusion, as a few travelers mention. Brenda_K noted, “It was a bit confusing at first in boarding the boat. First sat on the main deck. Folks on top deck were ushered to the submersible section.” Once settled, most agree that the trip runs smoothly, with staff generally described as friendly and helpful.
Some reviews, like Marialuisa_M, mention that the short duration and limited underwater activity might not satisfy those expecting a more immersive experience. Likewise, there’s mention of crowded conditions and seats being assigned, which may impact comfort levels, especially during busy days.
Group Size & Atmosphere

The tour caps at 46 travelers, which balances a lively atmosphere with manageable group interactions. Many found that the group size felt intimate enough for everyone to enjoy the experience without feeling overwhelmed. The friendly staff and smooth operations generally receive positive remarks, making the trip feel relaxed and well-organized.
Accessibility & Practical Details

For travelers with mobility issues, near public transportation makes this tour easy to reach. Service animals are allowed, and most travelers can participate without special requirements. However, the shortness of the trip and the confined spaces in the underwater section may be less comfortable for some.
Regarding weather, the tour is subject to cancellation in poor conditions, with a full refund available if canceled due to weather within 24 hours of the scheduled time. This flexibility is a plus, especially during unpredictable weather seasons.
The Bottom Line: Is It Worth It?

Considering the price point, the semi-submarine experience offers a cost-effective way to enjoy marine life and scenic views in Crete. Many travelers, including families and first-time visitors, have enjoyed this tour, emphasizing the friendly staff, good value, and the chance to see fish and turtles up close. However, the short duration and limited underwater visibility for some mean it won’t satisfy everyone looking for a deep-sea adventure.
If you’re after a relaxed, family-friendly activity that combines a bit of underwater exploration with sightseeing, this tour hits the right notes. Just be mindful of seating arrangements and the possibility that the best views depend on your spot and weather conditions.
Who Would Love This Tour?
This experience is perfect for non-swimmers, families with small children, or those who prefer not to get their face wet but still want to observe marine life. It’s also suitable for travelers on a budget who want a quick, scenic trip with some underwater excitement. If you enjoy informative guides and scenic coastlines, you’re likely to find this worthwhile.
Who Might Not Enjoy It as Much?
Those seeking a longer, more in-depth underwater adventure might find this tour a bit brief and limited. If you’re sensitive to crowded spaces or want a more comfortable, spacious environment, the crammed interior and busy seating assignments could be a downside.
