Long Island Aquarium and Exhibition Center


Patterned after the myth of the "Lost City of Atlantis," Long Island's only full-scale aquarium mixes education, ecology, and entertainment into a rich indoor and outdoor experience. From its 20,000-gallon coral reef display tank to its status as the home base for the Riverhead Foundation for Marine Research and Preservation, the Aquarium's relative youth (opened in 2000) is outpaced by its constant achievements in public education and wildlife research, as well as its attached exhibition/vacation facilities.


The Atlantis Explorer Tour Boat offers a lively, educational 90-minute escapade aboard the park's "floating classroom," traveling through the Peconic River into Flanders Bay, while staff explain the surrounding ecology and make environmental awareness fun. "Sleep with the Fishes" is a highly unique way for visitors (particularly children) to get up close and personal with the Aquarium's inhabitants during catered overnight stays. The Aquarium's Interactive Salt Marsh provides a fascinating glimpse into the worlds of tidal marshes, where fresh and sea water mix, providing vital ecological functions and serving as the home of horseshoe and spider crabs, whelks, and beautiful migratory birds.

Price range

Admission rates vary depending upon visitor age, date of visit, additional activities, and other factors.  Admission fees can be calculated here.

Best time to visit

Arrive early in the day if you'd like to feed the stingrays in the Ray Bay touch tank, because the creatures' caretakers monitor the animals' food consumption and have to "cut them off" as the hours pass.
