Very interesting and beautiful! The staff was very friendly and efficient! The guide on the submarine helped point out things that I would not have seen if he had not pointed them out!

Be aware that 4 is the minimum age. And the child needs to be somewhat confident and independent, because entry to the sub is tricky and could be scary. I didn't read the conditions carefully when booking, so we had to split our party so that a parent could stay behind with our 3 year old. OTHER THAN THAT it was a good experience. VERY well organized and friendly. Saw a gig variety of fish and a nice surprise at the end.

Need to know you have to pay an additional $13 fee per person to the government. Before they’ll let you into the waiting area for the experience.

Very good experience right from the start to end. The crew is very knowledgeable and clear in providing instructions that are required. Even my 3 and half yr old(height needs to be more than 42inches) also enjoyed the ride. Wouldn't say that the corals are the best but overall experience is worth. Also the place is very close to the port and would take less than 10min from the port exit.

Just as described but make sure you sit on the right side sees more than otherside. Not sure why we had to keep looking over to the ba k of us to see shipwreck and coral mounds.

It was spectacular to descend to 35 meters deep observing the marine species, and the most amazing part was being at the edge of a black hole that cannot be descended into and seeing how far the light reaches and the rest does not. Comfortable, calm, it feels completely normal. You look through the portholes very comfortably seated. Excellent experience to have once in a lifetime. (The date is different, but the system gave me options.)
