Nice place for kids

This is a mini aquarium compared to stateside aquariums. pretty small but the fish are beautiful. The facilities are really clean. My daughter loves this place.

Of all the aquariums I have visited this one is very average. However, for activities on Guam this one is pretty great for indoors. We did the aquarium dive as a family. It was fun but was not the experience we expected either. If you do the dive be sure to wear a suit and bring a change of clothes... More

My grandsons were fascinated by all the sharks, rays, turtles and fish you can see in this great underwater experience. You must be sure to go on a day when they are shark feeding in the tank. What a great experience!

Lived in Guam for over 3 years. I purchased the year membership for myself with the military discount. Children are free 2 and under. It's a great place to go with kids 5 and under, they have a small play area at the top after you walk through, where kids can color and put puzzles/Legos together. Great option for small... More

Fairly small aquarium but does good job at highlighting Guam's marine life. Consider having dinner here as you can dine in the walkway between the two halves of the aquarium seeing the amazing marine life while you eat.

We took our Girl Scout troop to Underwater World and they really enjoyed it. The event coordinator worked with us to get us the best group price, and was very accommodating when we had to reschedule due to a storm. The price was right and the exhibits were beautiful and well kept, especially the tunnel at the beginning. The only... More

Don't miss this if you like reefs and Pacific tropical fish.There are even sharks and sea turtles. They can be viewed while walking through an acrylic tube aquarium. I visit Guam every 2 years and never miss a visit to Underwater World. I recommend going in the hottest part of the day because this experience is air conditioned.

It's a long S-shaped, glass tube inside a water tank full of stingrays or mantas, sharks, sea turtles and other marine life. You can also pay $80+ to go down the tank using a bell-head-gear-breathing-apparatus (forgot what you call it) to be one with all the marine life. Of course, you have master diver beside you. If you're a group... More

Love this aquarium! Lots of interesting exhibits on Guam's sea animals. If you can go for the local price, it's worth it.

This was our second visit to Underwater World (see also my earlier review from June 2014). Again we decided to go on a day when the weather was not so great. Thankfully it wasn't very busy, so we took quite a slow stroll and sat for a while in the long tunnel. This time our visit was near the end... More
