Long Island Aquarium

Long Island Aquarium is one of the East End’s best-known family attractions, set along the Peconic River in downtown Riverhead, New York. Formerly known as Atlantis Marine World and later as the Long Island Aquarium & Exhibition Center, the destination is now widely presented simply as Long Island Aquarium. Visitors come for marine-life exhibits, hands-on experiences, educational programming, and a convenient riverfront location near shops, restaurants, and other Riverhead attractions.
History
The aquarium opened in 2000 as Atlantis Marine World as part of Riverhead’s waterfront revitalization. Over the years, it expanded its exhibits, guest experiences, and event offerings, and it remains a major year-round draw for families, school groups, and travelers exploring Long Island’s North Fork and East End.
Exhibits and Attractions
Long Island Aquarium combines indoor galleries, interactive areas, and seasonal programming. Highlights commonly include:
- Aquarium galleries: Core exhibit spaces feature a mix of saltwater and freshwater species, with displays that may include sharks, rays, reef fish, jellyfish, and animals tied to Long Island and Atlantic coastal habitats.
- Interactive touch experiences: Touch tanks and other hands-on stations help visitors get closer to selected marine life while learning about anatomy, habitat, and conservation.
- Penguin and specialty animal exhibits: Animal habitats and encounter-style exhibits are among the aquarium’s most popular features. Specific species and presentation formats can change over time, so it is smart to check ahead if there is something you especially want to see.
- Shark-focused experiences: Shark exhibits have long been a signature part of the aquarium experience, and special programs or up-close add-on experiences may be offered on select dates.
- Scheduled talks, feedings, and seasonal programs: Daily activities often add context to the exhibits and can make a visit more engaging for children and first-time guests. Offerings vary by season and may be weather-dependent.
Education and Conservation
Education remains a major part of the aquarium’s mission. School trips, youth programs, camps, and public presentations help introduce visitors to marine biology, aquatic ecosystems, and responsible environmental stewardship. As with many accredited animal attractions, conservation messaging, animal care, and species awareness are woven throughout the visitor experience.
Facilities and Visitor Amenities
In addition to the exhibits themselves, visitors will generally find convenient on-site amenities and nearby downtown services, including:
- Gift shop and guest services: The aquarium offers visitor assistance, orientation information, and souvenir shopping on site.
- Riverfront setting: Its Peconic River location adds to the appeal and places visitors within easy reach of downtown Riverhead’s walkable waterfront area.
- Group and event options: The facility is also known for hosting birthday parties, group outings, educational visits, and special events.
- Nearby dining and attractions: Food and shopping options are available in the surrounding Riverhead area, making it easy to pair an aquarium visit with a broader day trip.
