Exploring Crete often means wandering ancient ruins, relaxing on beaches, or savoring local food. But if you’re craving a unique glimpse beneath the waves without getting wet, the Agios Nikolaos: Semi-Submarine Cruise offers an engaging way to see marine life and spectacular coastal scenery in one relaxing ride. This tour, rated 4.1 out of 5 from over 670 reviews, combines comfort with discovery, making it a worthwhile addition to your Crete itinerary.
What I really like about this experience is how accessible and straightforward it is. First, the semi-submarine vessel is air-conditioned, providing comfort even on warmer days — a thoughtful touch for those who prefer to beat the heat. Plus, the onboard audio guide in multiple languages ensures you’re well-informed whether you speak English, French, Greek, German, or Russian. Another highlight is the chance to see colorful fish up close, with some reviews mentioning fish so well-trained they follow the boat — a fun detail that makes this trip memorable.
However, it’s worth noting that not everyone will see sea turtles or dolphins during their tour, despite the hope of spotting these creatures. The reviews suggest that sightings of these mammals are more luck-based, so if your main goal is to see dolphins or turtles, keep your expectations realistic. Also, as the tour doesn’t include food or drinks, it’s a good idea to bring some snacks or coins for the onboard vending machines if you get peckish.
All in all, this cruise is a simple, well-organized way to enjoy Crete’s underwater and coastal scenery without any hassle, fitting comfortably into a day’s sightseeing. Its blend of marine exploration and scenic views makes it a solid choice for families, single travelers, or anyone curious about the local marine life.

Starting the Adventure: Easy Logistical Setup
The tour begins at the “Semi-Submarine” ticket counter at the port of Agios Nikolaos, manageable for most travelers. Arriving about 20 minutes early ensures you won’t miss the boat, and the process of boarding feels smooth thanks to clear instructions and helpful staff. The vessel itself is modern and well-maintained, with the air-conditioned interior providing respite from Crete’s sun.
What Happens Onboard
Once aboard, the boat starts its journey with a gentle cruise through the waters surrounding Agios Nikolaos. The semi-submarine design lets you enjoy the underwater world without getting wet—your head remains dry, while large viewing windows give you a nearly underwater experience. The audio guide is a nice touch, offering details about local marine flora and fauna in multiple languages, which makes the experience educational as well as entertaining.
The Underwater Viewing Experience
The main draw here is the marine life. Guests often see schools of brightly colored fish, some of which are apparently trained to follow the boat, as one reviewer noted. It’s quite amusing to watch these fish swim alongside the vessel, especially when the crew feeds them, drawing even more attention from the underwater guests.
While sightings of sea turtles and dolphins are always hoped for, reviews suggest that such encounters are somewhat hit-or-miss. One reviewer recounted missing out on seeing turtles, but still found the experience “really lovely.” The crew’s friendly attitude and informative commentary add to the enjoyment, whether or not you see the larger marine mammals.
Scenic Bay Views and Relaxation
After the underwater exploration, the boat returns to the main deck, where you can take in stunning panoramic views of Agios Nikolaos Bay. The breeze, the scenic mountains, and the quaint villages lining the coast make for perfect photo opportunities. Many passengers enjoy just lounging on the deck, soaking in the scenery, and feeling the sea breeze.
Who Will Love This Tour
This experience is particularly well-suited for those with limited time, families with children, or anyone looking for a relaxing, low-effort activity. It’s also perfect for travelers who appreciate a good value — at just over $18, you get a solid hour of marine and scenic sights, with the added comfort of an air-conditioned boat and multilingual narration. For those who prefer active snorkeling or diving, this might not be the best choice, but if you want a gentle, educational, and visually engaging experience, it’s hard to beat.
Price, Logistics, and Practical Tips

Pricing at around $18.63 per person makes this cruise accessible, especially considering the level of comfort and the educational value. Remember, the tour does not include food or drinks, so packing a few snacks or coins for onboard vending machines is smart if you’re hungry mid-tour.
The tour is valid for 7 days, allowing flexibility to choose a time that works best with your itinerary. It’s best to check availability ahead of time, as popular sessions can fill up, especially during peak season. The group size tends to be manageable, and the multilingual guides ensure clear communication.
Since there’s no included transportation, you’ll need to get to the port yourself — most likely walking or a short taxi ride from your hotel. The activity is wheelchair accessible, which is a considerate feature for travelers with mobility concerns.
Tips for the Best Experience
- Arrive 20 minutes early to avoid missing your departure.
- Bring sunscreen, a hat, or sunglasses — the outdoor deck gets sunny.
- Pack some coins for snacks or drinks from the vending machines.
- Listen carefully to the audio guide for interesting facts about marine life and the local scenery.

This tour suits travelers who enjoy gentle adventures, value good narration, and want to experience the marine environment from a safe, dry vantage point. It’s especially appealing if you appreciate honest reviews about seeing the marine life up close, and if you’re comfortable with a moderate, paced activity that doesn’t demand physical exertion or prior experience.
