My daughter, niece & I were able to swim with the sharks, rays & sea turtle!! What a neat experience!! The cost was about $90/pp, but I would say it's worth it! I didn't want to pay $250 to get scuba certified, being sure I'd probably never go again - this way I was able to have the similar experience.... More

we came to underwater world as it's right next to the hotel. there's a tunnel in which you can see fishes / sharks / sting rays / turtle swimming in the 1st floor. Following that, the 2nd floor has some windows to keep corals / coral fish. If you are coming with kids, they would probably enjoy but it is... More

Eventho it was a small atrraction, the quality of the fishes and the place made it all worth it. My 2 daughters (9 and 5) loved it!

I took my teen daughter with me to check out Underwater World. We got the local/military rate so it was $23 for the both of us. It took us only 30 mins to go through the exhibit and we read most of the signs along the way. We spent a good bit of item in the tunnel area watching the... More

Reasonable price for the lovely visit. You walk through a tunnel with the turtles and sharks swim above you. Clean and informative.

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.
