This place provides some educational fun and is an attraction worth the entry fee. It's worth an hour or two of your time to see it. The walk-thru venu puts you close to the marine critters so it is a good place to take some photos as well.

I took my toddler here and she loved it! She was really engaged with the different types of sea creatures. I like that even the staff in the aquarium in scuba gear were entertaining. We even got to see a sea turtle. The upstairs area was also a nice treat. My daughter liked the anemone fish and the jelly fish... More

The Underwater World is an aquarium who has a tunnel where you can walk through and see the fishes and sharks swimming around you. There are a lot of variety of sea creatures to explore and the coral are colorful. Highly recommend to visit the place.

Fantastisk Underwater tunnel. Very interesting to be able to see and make video of the sharks. The video is excellent for your FB time line.

I've gone to underwater world several times. It's a short visit but it's worth the chill vibes if you like the calmness. You can bring in a camera and take pictures, just make sure there is no flash photography though. I went there so many times that by now I know most of the fish names in that aquarium. I... More

This is an especially good even for a rainy day in Guam! The aquarium is small, but informative. I could have spent several more hours in the tube, watching the sea life swim around!

It is a great little aquarium! Took our grand-daughter one morning and we all had a blast! They have a great array of fish, large and small. The price per person is a little over the top but we paid military and it was so worth that rate!

This is a cool , tunnel style aquarium where you are on display to the fish more than the other way around. Located in the Plaza shopping center, this was a great way to spend a rainy afternoon when the beach was not an option. They have numerous local fish and shark species, as well as some non-local species in... More
