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

I went with friends and were amazed with the school of different fish inside. It is also good for kids to view from small to big fish including one big turtle. There are seats inside when you feel tired and still want to view the marine world. The walkway is however small so it is best for a small crowd... More

Those who would like to see Sharks and Sting Rays but do not want to get wet, this is a chance. The concave glass walls kinda makes you dizzy, but you'll get used to it. You can also ask to dive in for another fee if should you wish to.

Good for adults and kids to explore the underwater world. Walk through the tunnels underwater to see all kinds of marine life. Checked out the huge garoupa, sharks etc.. Pricey but if you are local, get yourself an annual pass. Worth it.

We went with my brother, sister in law and nephew, and had an amazing time. The two year old was captivated running around to look at the variety of fish. What you couldn't see up close in the big, walk-through tank, you could look more closely at in the smaller tanks. I loved that there was a gift shop at... More

I had the year pass. It was excellent because there aren't very many children's play areas on the island for non school age children that are indoors in the Tumon area or during the rainy season.

Got the package with dinner. Includes 3 day pass to the site. It was too short a tour compared to other under water adventures. But the kids love it anyway. Best part was the dinner inside. See my pics was an awesome experince for first timers like me. 😀
