Aghios Nikolaos Harbor. Exactly in front of the boat, you can find the ticket booth. Even if the boat hasn't returned from a tour it's easy to reach the ticket booth as it is only 100-150 meters away from the lake bridge, one of the most famous spots in Aghios Nikolaos.

Nice! - Nice trip across the sea. Being able to see the sea world underwater. Please note that you may get seasick if you participate in this excursion

Something else - First of all, the price-performance ratio was right. We chased a nice trip, yet there are a few prints. Everything had to go the way the crew wanted. The friendliness fell a bit by the wayside. Below the deck there is a kind of glass cabin with a bench in the middle on each left and right. If you're lucky, you sit with your eyes out. There you can definitely see more. In the places for fishing observation, food is thrown into the water, so that some fish are also attracted. At the end of the tour you are asked to the deck or upper deck and you take a small round trip on the coast of Aghios nikolaos which was very informative and interesting.

Short and sweet activity - For the price, this trip under and on the sea is the perfect activity with your kids, it's short and sweet before exploring the wonderful city of Agios Nikolaos. The crew could be a bit less serious, it's a chill job after all...

Nice experience but a... - Nice experience but a bit taken aback when the park guide said women on one side, men on the other... In fact, there are 2 lines on the boat, so 2 where you can see the inside of the boat and 2 the outside... In other words, the women saw the inside, which was nothing, just 2 or 3 fish that got lost between the 2 parts of the boat, while the men were able to admire all the wildlife.

Mixed opinion: it all depends on which side you are on! - Mixed experience. My husband and I were back to back... the staff on the boat put us like this. Except that we were not allowed to change places and as stated in other opinions, one side of the hull is facing the other hull (it is a catamaran) and therefore sees nothing. For those who are outward-looking, it is indeed much more interesting!

Beautiful experience for half of the tourists, disappointing for the others - It could have been a 5-star trip; unfortunately, a few small shortcomings spoiled the overall impression. What we liked: 1. The trip was long (I mention this because, in other Greek ports, we had the unpleasant surprise of being back at the pier in less than half an hour). 2. It wasn't just long, but also very interesting: we saw many fish, and the underwater landscape was varied and beautiful. We especially enjoyed the moment when, on one side of the ship, we could see the edge of the sea abyss — it's fascinating to look into that endless depth. 3. The crew was very kind. 4. During the trip, the guide shared a lot of interesting information. 5. The return journey, when we went up on deck, was also very pleasant. What we didn't like: 1. In an attempt to maximize profit, the owners load the ship to the brim. Personally, we would rather pay a bit more than be packed like sardines in a can. 2. We had the misfortune of traveling with several families with children, who expressed their enthusiasm in an age-appropriate (but noisy) way. The result: we returned with migraines. It might be a good idea to organize separate tours for families with kids. 3. One last point, which I mention only for the sake of objectivity: we had seats facing outward, and the view was fantastic; those seated on the inner side saw almost nothing... perhaps only the disappointed faces of the unlucky tourists in the opposite compartment.

Many fish - If you're unlucky, you sit inside and have limited visibility. Underwater it is beautiful but nothing special Fish are fed to attract them, which is a bit of a shame.

Pretty boring after the first few fish - Make sure you seat kids on the side.with the large windows. I think the guys running it could also be a bit friendlier.

Insufficient - The boat has 4 rows of seats “Underwater”. If you are assigned to the inner row, you unfortunately do not get your money's worth. I cannot recommend this dive boat.

Draught hopeless! Makes no sense and waste of money - Very unfriendly staff We weren't allowed to decide where to sit. We wanted a better place, but we absolutely couldn't! We were looking at the oder side of the boat and were annoyed by the noise of the engine, and the unintelligible translation. Like Herrings we sat on top of each other, we've seen the same fish all the time and a few old tires on the bottom This is a real waste of your money! In Diergaarde Blijdorp you see in the Oceanium lake !! Not recommended so
