Visiting the Long Island Aquarium With Kids: Must-See Things

The Long Island Aquarium isn’t particularly large, but it packs a lot into its square footage. There are exhibits both indoors and out, and the best plan of attack is to make your way through the lagoon and shark tank before heading outside. Butterflies are located just past Ray Bay at the beginning of the aquarium, so it can be the first or last part of your day. 

Ray Bay

Get up close to cownose, southern, and Atlantic rays. Put your hand in as they swim by to touch the tops of their bodies. Food can be bought when you first enter, either at the admission register or at Poseidon’s Crafts. There is a certain amount allotted for each day, so when it’s gone, it’s gone. When feeding the rays, it’s best to stick the fish standing up between two fingers and place your hand against the wall. The rays will suck it right up like a vacuum. It’s a fun experience, and on busy days it’s usually crowded. The rays are known to splash, so don’t be afraid to get wet.

Stop by the Ray Bay early in the day to feed stingrays before they sell out of their allotted feedings.

Butterflies, Bugs, and Bees

Just past Ray Bay is the butterfly exhibit. Here you’ll get up close with various butterfly species. It’s important to watch where you walk, and no strollers are allowed inside. Every day something new is hatching from its chrysalis, so each visit is never the same. This unique exhibit is the only one of its kind on Long Island.

Touch Tank

It’s easy to overlook the touch tank, located just past the bridge of the lagoon, but skipping it is a mistake. Visitors can touch various sea creatures, like starfish, clams, spider crabs, and whelk. The staff here are the real stars, offering up unique facts and picking up the creatures to show off cool features. Future marine biologists can easily spend lots of time soaking it all up.

Even little ones will be awed by the stunning reef. 

Lost City of Atlantis Shark Habitat

The themed decor and architecture of the aquarium are beautiful, and there is no better example of this than the shark habitat. As soon as you enter the tunnel, ominous music and dim lighting set the mood. Watch carefully as sand tiger sharks and nurse sharks lurk past Poseidon’s trident. Other large fish like the Queensland grouper and moray eel inhabit the tank as well. If you go up the stairs or take the elevator, you can see the tank and sharks from above.

Watch in delight as sea lions dance and perform tricks with their human trainers. 

Sea Lion Coliseum

A few times a day the aquarium puts on a sea lion show. Trainers give educational information on sea lion training as the sea lions entertain the crowd. They wave, dance, and even do a high dive. On crowded days, arrive early to get a good seat. Strollers must be parked and are not allowed in the stadium seating. Once the show starts, the doors are closed and no one will be allowed to enter.

Penguins

Try to catch the penguin exhibit when they are holding the “penguin talk-and-feed.” A trainer will be in the habitat to talk about the African penguins and answer visitor questions. The penguins are usually very active during this time. A penguin lecture is held inside the Sea Lion Coliseum at 11:30am Monday through Friday, 11:15am Saturday and Sunday, so guests can still see a penguin.

Handle horseshoe crabs, spider crabs, and whelks outside in the salt marsh.

Marsh

Take off your shoes, pull up your pant legs, and step into the marsh. Horseshoe crabs, spider crabs, and whelk roam the sand beneath your feet. Visitors must be 42.5 inches or taller and out of diapers to enter the marsh.

Eye Opener and Rock Wall

This multi-story climbing structure features rope bridges, spiral tube slides, and a climbing net. As a bonus, for the $12 admission (parents are free) to the Eye Opener, you also get four climbs on the rock wall. The Eye Opener has a spectacular view at the top. It is open on weekends and holidays, but on many weekdays they allow access to the climbing structure for FREE.

J&J Mining

Open on weekends and holidays, mine for gemstones inside J&J Mining. During the off-season, it is only open on weekends, but it’s open daily in the summer. A bag of gemstone and fossil grit is not included in admission and costs extra.

Visiting the Long Island Aquarium With Kids: Dining Options

Atlantis Cafe

This is the main dining area at the aquarium. Some grab-and-go foods include chicken tenders, fries, pretzels, salads, and wraps. You won’t find anything to excite your palate, but it keeps the kids from getting hangry. There is a 10% discount for aquarium members.

Scoops Ice Cream

Scoops serves up Edy’s ice cream and sweet treats. It’s often closed during the colder months, but it’s a welcome treat on warm days.

Pack Your Own

The most cost-effective option is to pack your own lunch. There are plenty of outdoor seating options. The covered deck next to the Eye Opener is great for those with small children since it’s mostly fenced in.

Magic takes over the aquarium with a visit from a mermaid.

Swim with Mermaids

Snorkel with a mermaid in the Shark Reef Lagoon. Dive amongst tropical fish, and glide alongside a real mermaid. It’s a beautiful and amazing sight to see the women swimming so gracefully with their iridescent tails flittering behind them. Sometimes, mermaids pop up to say hello to visitors and take pictures with them. It’s a magical experience when you happen to catch one there. Dives are offered on Mondays and Fridays, and are an additional $49. Wearing your own bathing suit and bringing your own snorkel gear is recommended.
