UnderWater World reviews
Expected more to see for what they charge. It’s very small a bit run down in need of updating and bringing to 21st century . more »
Pretty solid and fun setup. Feels like you are walking through an underwater spot and you can do it right in Tumon Bay. Not bad, little pricy but we learned a lot about the waters and unique elements.... more »
It's a an aquarium but unlike any other aquarium however... You are inside, that's right at Underwater world the aquarium surrounds you as you walk through the tunnels that go throughout the aquarium giving you exquisite views of the Sharks, Turtle and more that float over your head or just beside you. They also hold dinner here during evening hours, we haven't done that yet so I can't speak for the quality of food.
Last time i went to UnderWater World i was in 5th Grade. The turtle definitely grew. It was exciting then and its still exciting now. Maybe because this time around, i can fully appreciate sea creatures and learn more about them.
