A 5-Star Underwater Experience
"My husband’s family is from Guam and he grew up there. When we had the opportunity to bring our 3 and 6 year olds we jumped on it! Underwater world was SO MUCH FUN for us as well as the kids. They loved the long walk through tube aquarium. Watching the giant sea turtle, multiple types of sharks, massive groupers, sting rays, and many beautiful fish swim around and overhead was quite an experience. I’m so please it’s still a staple attraction in Guam as my husband speaks fondly of it from growing up."

"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. :)"

"I was scared but my friend wanted to go so I brought my little sister along. When we went there, they went over the rules and had briefing. Then we finally changed and the moment we went in the water it was freezing cold... So it was a little hard to go in.. When we were in the water, it was a little better. We were able to see sharks and other fishes up close and also got to experience touching a shark's egg. Pat and Cyle were very nice and they made our experience fun. I want to go back next time with my boyfriend."

"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 display. The best part about Underwater World is the local rates and kids under a certain age goes in for free."

"We had a great time. My nephews come here often, and they had fun too. On Wednesdays and Fridays they feed the sharks in the tanks so we got to see that, it was very cool. Since our visit was so close to Christmas, the divers dressed as Santa and his elves which was also awesome."
