So starting from the beginning, the parking was terrible and we almost got run down by a tour van that was speeding through the parking lot. There was no wait to get tickets at the counter. Tickets were $23 each, which seemed a little high. The entrance to the aquarium was a dark jungle themed tunnel which was cool, but... More

A quiet private way of spending time, if you're alone that is. If you're with a big bunch of children like Christmas season, you'll see divers in Santa Claus costumes feeding the fishes including the sharks, turtles, & others. Feeding time at 2pm is a good time to bring the children. One year membership saves money for families & schools.

I've been to lots of aquariums. I can't say this one was terribly different. However, you can snuba (helmet with air) with the fish... I didn't do it but it looked really cool. Plus it's located in a shopping area so there's lots to do before or after the aquarium visit. (Dec14/Jan.15)

Beautiful aquarium with a nice variety of fish and turtles. Great for kids of all ages and adults too. A must see while in Guam.

If you want a break from the heat or rain, this is the place to go. Literally walk through a giant fish aquarium. Get great pics of reef fish and you can even opt to get in and swim with the fish (and sharks).

I brought my family here. Very nice aquarium. They have a good-sized walk through tunnel with several fish, sharks and manta rays swimming around you and over you. We paid the little extra for their treasure hunt which kept the kids more involved. Overall, a nice experience.

We really enjoyed ourselves and got some great pictures. It was an educational experience and it was great to see the sea life up close. We've been to the Monterey Bay Aquarium and so we are a bit spoiled, but we enjoyed this experience.

A good break from the hot sun. Not very big though so you might go through it pretty quickly. Benches line the walkway though so if your kids allow it, you can take as much time as you like.

This is NOT as big or impressive as other aquariums I've been to (Monterey & the Living Planet in Utah). BUT way cheaper and certainly worth the visit! My two year old didn't want to leave! I received a discount- so it was only $11 for myself, my two year old and baby. The underwater aquarium is brimming with all... More
