  • Our favorite part of visiting the aquarium on March 29th 2021 was the Shark encounter. It was a birthday present for my 12 year daughter. It was great to see the sharks and all the other fish up...  more »
  • I did the Shark Dive for my birthday. It was ABSOLUTELY THE BEST. Jim was a wonderful instructor and made the experience safe and memorable. There was a good 45 seconds when I got in the water...  more »
  • At first glance its very pricey but after hours of being there; and constantly entertained you'll realize that its a great value! We loved the seal show and the shark exhibit! The entire place was built to impress and amaze. My son loved being able to pet and feed stingrays, and all of the animals are treated with respect and you can tell! The animals love to put on shows for you when they see you.
  • I’ve been going to this place since it was Atlantis Marine World, and to be honest it hasn’t changed much since. That’s not a bad thing, but you can tell that it could use a little updating. I don’t know the last time they added anything significantly new. It’s also fairly pricey! But it’s Long Island, it’s an aquarium, and you do get a good amount of “stuff to see” for your money. All in all a good day trip, fun for the whole family with enough to keep everyone entertained for a while. My favorite part is probably the bird & butterfly exhibit, although the shark tank can’t be beat. Go in good weather and explore the outdoor bits!
