  • Overall an experience worthy of our time and money once. Food was excellent, although the entree size was disappointing (the filet size was probably not more than 2 oz and very small lobster tail...

  • Giving five stars because of the seatrek experience! We haven’t been home (to Guam) since we left when I was about 3 years old due to my dad being in the military, so I made my mom do it with me and she was super nervous about it! But the divers were super fun to be around and made sure everything went smoothly and that everyone was safe and having fun! The experience was so amazing and I loved being able to be so close to the sea turtle and able to touch it, I LOVE sea turtles! If we were staying on Guam longer, I would have taken up dive classes somewhere, but this was such a great alternative! I even got a little shark tooth from one of the divers there! The pricing for videos and images can be pricey, but well worth it, this isn’t an everyday opportunity for most people. I went with the most expensive package so my mom and I had all the videos and images to look back on and show our family state side. This aquarium in general is a cute little place to go with the kids, I highly recommend visiting if you’re here for a little while. Read about the marine life and see the beauty of it as well! Shout out to the divers - YALL ARE THE BEST! :)
  • I haven't been here since i was a little girl in 2009. This place changed a lot. I still enjoyed my visit. I was here on a environmental biology project and I was able to take many pictures and learn different types of fish and their habitats.
