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.

Great trip - We had a wonderful trip. We are a 3 generation family from the UK with children aged 15,10 and 5 and we all got a lot out of the trip. The captain and his staff were very friendly a d keen on safety. The children had been told they were going o a boat trip so were very surprised when we got there and realised they could go under the water to see the fish of which there were plenty. All in all good value for money.

Beautiful excursion - I thought it was super nice you saw a lot of fish. They were not very varied because you have seen several species more times.

It's worth it! - A great tour with a very good value for money. During the 1.5h tour there was multilingual and easy to understand information both above and below water. A star deduction for the way seats are allocated.

A fun diversion - We were a little disappointed that as we were led down into the viewing hulls our family were separated so that the children faced out directly onto the view underwater and my husband and I had the less impressive view of the people in the opposite hull. However, once we got going we stood up and spent most of the trip looking out the children’s side anyway. We saw lots of fish of the same variety and a few Barracuda. Halfway through the allotted time we were told to come up on deck and the rest of the trip was sightseeing from there. To be honest, that was fine as sitting below was quite cramped after a while.

Fish in their natural habitat - If you get seasick quickly, you better take something against it first! The view on the way back was beautiful. The fish variety is so lala. But if, like me, you rarely snorkel and never dive, it's nice to see wild fish in their natural habitat. If you sit inside, you can just turn around or stand outside. Actually not sooo the problem.;-)

Greate experience for children and people not snorkling. - If you go snorkling you will get the same experience, though the fish are a little bit larger. When your are seated under the waterline, try to get seated looking out of the boat (that's where the action is), not looking towards the center of the boat. But a great experience for children.

Interesting but not for the faint of stomach - An interesting concept, however I wouldn't recommend a large meal prior to setting sail. It was cool and informative, but for someone that doesn't get sea sick it was a bit trying. Definitely a no go if you are claustrophobic. The underwater portion is a fairly limited area. The upper deck part was very pleasant.

Too bad, marine life must be beautiful - It is an old catamaran because a heavy diesel engine is not normal anymore what a noise. Plexiglas for the real glass panes full of scratches. You can no longer hear the announcer because of the noise of the diesel engine. 4 to 5 species of fish seen in all kinds of groups. She fed them with food to get in front of the glass. Only the outer row of people saw anything. In the middle you see each other and nothing more. Catamaran so 4 rows of underwater, 2 opposite each other in the middle. Everyone from the middle on the outside is looking over your shoulders to see something, changing spots. Seen an old car tire.... what a mockery.
