Long Island Aquarium

The Long Island Aquarium throws its visitors into the shark tank. And the tropical lagoon. And the salt marsh. As executive director Bryan DeLuca noted in the New York Times, the center (formerly Atlantis Marine World) is one of the most interactive aquariums in the area, which snagged it a place on Parents magazine’s list of the 10 Best Aquariums for Kids. The Atlantis-themed aquarium’s educational exhibits combine myth with science as they bring guests face to gills with creatures such as eels, jellyfish, seals, and clownfish. In addition to its indoor and outdoor exhibits right on the banks of the Peconic River, the aquarium delights guests with aquatic adventures such as snorkeling or receiving a photo op and kiss from loveable sea lion Java, who still dreams of one day being turned into a beautiful princess. Additionally, they offer rides such as the Atlantis Explorer Tour Boat Ride, which travels down the Peconic River to educate riders on Long Island’s waterways.
