This is a must see, it is a bit on the touristy side of thing to see but it is one of the best aquariums I have ever seen, the only thing better is a scuba dive with the fish

Sitting in the heart of Tumon is a jewel filled with beautiful, colorful fish. Walking through the aquarium is soothing as the senses are filled with numerous species of sea life. Information is posted at every exhibit. You set your own pace. There are benches where you can sit and relax and just marvel at your surroundings.

The Underwater Steak and Lobster was a fun meal option at Underwater World. The kids had the choice of hamburger, teriyaki chicken, or spaghetti. You can't beat the atmosphere though as the sharks go whizzing by. An experience we'll never forget. Nice, friendly staff too.

The admission fee was a bit overpriced because the Underwater World itself is small, you can barely take pictures without people walking in on your pictorials, it offered weird animals which was an absolute plus and it had a few fun activities like the sea trekking which enables you to swim with some of the animals there.

This is Guam's only aquarium. The best time to go is during the shark feeding, but it does get crowded during those times. There are 3 parts to the aquarium, the first is a very short mangrove section that briefly shows some of Guam's land animals. The second is the main aquarium with a tunnel that allows you to walk...

Went to Underwater World during my visit to Guam in Feb 2015. Loved visiting this aquarium as it was one of the first attractions I went to in Guam. Spent about 30-45 min going through aquarium taking various pictures of sea life along with human life. Actually took several pictures of my dad smiling which is hard to do as... More

Great little walk through under the sea! If you're into sea life but hate the water, you should do this! Wish I would have done the under water walk, but ran out of time! We enjoyed it so much that we did it twice. They offer a great military discount too!

The aquarium is fairly large and the underwater tunnels you walk through feels cool. The variety of sea creatures is smaller than other aquariums I've seen.

The aquarium is quite nice but very small. My 3 year old loves it and we go often, as we have a yearly pass. It talks about 20-30 minutes to go through the entire aquarium with small ones. It would be great if it had more interactive activities for children.
