Experience to live - Original excursion in this semi-submarine to explore the seabed. We were able to observe different fish and corals with sunlight that gave an incredible atmosphere

Nice. - Original exit, we see common fish (the same as you will see if you snorkel) but difficult to see more "rare" specimens. Nice swimming trip before the end of the course.

Original and pleasant semi-submarine tour - The activity is consistent with its description. The captain, is friendly and competent the exit was commented throughout the visit. Made with two children 6 and 4 years old, absolutely delighted. The duration of about 45 minutes is suitable for children. Very pleasant and original activity, even if the seabed is not very rich on this side of the bay, we have seen the species that populate it. A suggestion, why not make a visit also at night?

Correct but not crazy - We went out on a semi-submarine. So I'm just talking about this exit. I am a little disappointed with the service but I specify that the staff for the booking is very friendly, and also very accommodating. Regarding the exit itself, the boat goes to a site and does not move. The pilot was not hypercommunicative, limits a little jaded. Not a crazy excursion. Proper experience.

semi-submarine - Since the usual fish and sea urchins, 0 octopus, 0 rays, 1 starfish, 0 moray, in short the concept is nice but do not expect anything other than a small sea walk underwater, the price being still very acceptable and the city of Porto beautiful. It's better to take the boat, we see more things. A nice day, though. Welcoming very friendly.

Semi-submarine tour - A little disappointed because we were told at the time of booking that we could swim in the open sea but it was not offered to us at all and not much to see except a few small fish and plastic floating....We made 4h drive back and forth for finally not much.

Semi-submarine ride - Outing at 25€, so reasonable, and fortunately.... We drove 1h30 for this semi-submarine ride and were disappointed with the service. The captain arrived almost 10 minutes late, without any explanation, and not even a day before he boarded the boat. Not talking for a penny... Once the contact was made, we had the right, in everything and everything, to "hello, your name, goodbye". As for the ride itself, well we don't see much... We must have seen two or three species of common fish and rocks. I understand that this is a little lucky, but maybe if the ride would be made somewhere other than the bay of Porto. On the other hand, the Telephone Welcoming is very good and the person we had online, very friendly.

Too bad. - Frankly, nothing to do with it. Fish seen are also seen from the surface. Captain not very cheerful. More seasick when I've always been boating. Dear for what it is.
