While this aquarium is nowhere near as large as some of the other aquariums I have visited, it offered a fun way to enjoy a rainy afternoon. The aquarium costs $23 per adult, but is half price for military and locals (just show your Guam driver's license). There was no line at the ticket counter and we walked right into... More

Good collection of fish, good experience for kids, although not very unique compared to other countries

My daughter and husband did the Sea Trek package and enjoyed themselves. The Sea Trek did not last very long. It should have been longer. The Aquarium is just one big tunnel in a shopping mall but a nice outing on a rainy day.

Nice place to visit and see all sorts of sea life up close. A little over priced for how small the place is, but it is geared towards tourists.

Not too bad, just did the walk through, right before dinner so they were setting up tables. Nobody was rushing us, though. Nice variety, had a good laugh at the eels. Those guys are goofy. The dinner seemed rather expensive so passed on that, though as close as they were setting up the tables it didn't seem that intimate, while... More

This was our second time going to Underwater World and this time it was much less crowded than before. It was much better without all the people! Watching the fish swim by was magical, especially when they just "appeared" overhead. The second part of the Underwater World, where we looked at fish in tanks was cool too, but less enjoyable...

We did the SeaTrek and 3 day aquarium pass. Recommend doing the SeaTrek before going in the aquarium then it's all a surprise as it was for us! You can't touch the animals but the turtles and sharks and fish came so close, it was the most exquisite experience ever especially with my boyfriends mum watching us from inside the... More

SeaTrek was so awesome! I saw turtles, different types of sharks, sting rays and a giant grouper. They have a young spotted eagle ray that was so playful and would swim right up to us! My one year old watched from inside the aquarium while I dived! She loved seeing mommy in the water! This was the most unique experience... More

I have been to most of the world's top aquariums including Okinawa, Genoa, Sydney, Valencia and Dubai. I felt that Underwater World wasn't on par with any of those... but it did fill in a day in our holiday when the weather wasn't so great and we decided to do something other than go to the beach. The aquarium is... More

One of the greatest indoor aquarium in the world. The facility is not new and impressed, but kids had lots of fun in the tunnel. This is more important than anything.
