South Carolina Aquarium

The Aquarium sits at the end of Calhoun Street on Charleston Harbor, at 100 Aquarium Wharf. It is open daily from 9 a.m. to 5 p.m., with the last entry at 3:30 p.m., and a typical visit takes about two hours. What separates it from other mid-size aquariums is that a real, working sea turtle hospital operates on the first floor, and your ticket includes a walk through it.

What it is

The South Carolina Aquarium opened on May 19, 2000, and it is a 501(c)(3) nonprofit, not a commercial attraction. The clearest evidence of that is the sea turtle hospital downstairs, which the Aquarium has run with the South Carolina Department of Natural Resources since the year it opened, funded largely by the ticket you just bought. The building holds more than 5,000 animals, and the exhibits are organized around South Carolina itself: you follow the state's water from a mountain stream down to the open Atlantic. That means river otters (Charlie and Beau) and a bald eagle named Liberty in the Mountain Forest gallery, a twilight cypress swamp with gopher tortoises and rattlesnakes in the Coastal Plain, and a saltmarsh aviary where roseate spoonbills wade over a 6,000-gallon tank of diamondback terrapins.

The centerpiece is the Great Ocean Tank. It holds 385,000 gallons, drops 42 feet, and is the deepest aquarium tank in North America. More than 500 animals live in it, including sand tiger and nurse sharks, stingrays, and a 220-pound loggerhead sea turtle named Caretta. The tank runs through two floors of the building, so you see it first from the surface and again at depth, where the sharks cruise past a wall of glass. Divers enter the tank for scheduled feedings and talks most days; check the daily program board when you arrive.

A rotating gallery, the John A. Hill Family Discovery Gallery, currently holds Jurassic Seas, an exhibit of Late Cretaceous marine fossils and life-size skeletal replicas. It is included with admission. The one thing inside it that is not is Dinosaur Evolution, a virtual-reality experience that costs $8 per guest or $7 for members. Skip it unless your kids are specifically after dinosaurs; the live animals are what you came for.

The sea turtle hospital

The Aquarium began rescuing sea turtles with the S.C. Department of Natural Resources in 2000, and for 17 years the hospital worked out of a basement space most visitors never saw. In May 2017 it opened Zucker Family Sea Turtle Recovery, a $5.3 million expansion that moved the whole operation onto the first floor, in public view. It nearly doubled patient capacity and added room to treat adult loggerheads, which can top 300 pounds.

This is not a staged exhibit. The turtles in the tanks are actual patients, brought in with boat-strike injuries, fishing line entanglement, or cold-stunning, and each has a name and a chart posted beside its tank. You can look into the surgical suite and the CT room through glass, and an interactive station lets kids triage a mock patient the same way the veterinary team does. By mid-2025 the hospital had treated and released more than 460 turtles, and the running count passed its 400th release in March 2024. When a patient recovers, the Aquarium releases it on a local beach, often with the public invited to watch.

Visiting today

Tickets are sold through an online calendar up to 60 days in advance, and pricing is dynamic: the Aquarium sets each date's price based on demand, and a posted price can rise as the date approaches but never drops. As of mid-2026, most dates land between about $29 and $38 for adults (ages 13 and up) and $23 to $30 for children ages 3 to 12, with kids 2 and under free. Weekends, holidays, and school-break weeks sit at the top of the range. Check the official ticket calendar for your exact date.

Your ticket is good for the whole day, and re-entry is allowed if you tell Admissions before you step out. The Sea Turtle Cafe serves lunch from 11 a.m. to 3 p.m., strollers are welcome, and the building is fully indoors apart from the harbor-view decks, which is why it tops most rainy-day lists for Charleston.

The thing most visitors miss is the daily program schedule, and building your two hours around it changes the visit. Staff run free talks and feedings on the hour and half hour: Turtle Talk at the sea turtle hospital at 11:30 a.m. and again at 2 p.m., Animal Encounters in the Great Hall at noon with a creature you can usually touch, Dive Into the G.O.T. at 3 p.m. when a diver goes into the Great Ocean Tank and talks to the room through a mask microphone, and Stingray Cafe at 4 p.m. in The Shallows. Arriving at 11 a.m. or noon catches the most programs before the 3:30 p.m. entry cutoff.

For kids, the second floor is the main event. The Boneyard Beach Touch Tank, which opened in May 2025 and doubled the size of the old touch tank, lets them handle sea stars and touch stingrays and small sharks under staff supervision. The Shallows has cownose rays and horseshoe crabs viewable from above and below the surface, and a stingray feeding costs $5 extra per person. Between those, the otters, the dive shows, and the turtle hospital, a family can fill three hours without trying. It is the single most reliable stop on a Charleston trip with kids.

If you live nearby or expect a second visit within a year, do the membership math. A Family membership is $249 and covers two adults plus your children under 18. A family of four pays roughly $120 or more per visit at gate prices, so the membership pays for itself on the second trip, which is exactly how the Aquarium pitches it.

Is it worth it?

With kids under ten: yes, without hesitation. It is the best indoor attraction on the peninsula for that age group, and the touch tank plus turtle hospital combination beats anything else downtown when the weather turns.

For adults traveling without kids, be honest with yourself about the price. This is a well-run, mid-size regional aquarium, not a Georgia Aquarium-scale megafacility, and two hours covers it comfortably. The Great Ocean Tank and the turtle hospital are genuinely good; the rest is pleasant but familiar if you have visited other aquariums. If your Charleston time is short and animals are not a priority, a history-focused day may serve you better; our things to do guide lays out the alternatives.

Getting there and what's nearby

Drive to the city-run Aquarium Garage at 24 Calhoun Street rather than the Aquarium's street address, which confuses GPS routing. The garage charges $1 per 20 minutes with a $24 daily maximum and takes cards only. On foot, the Aquarium is roughly a half-mile from the City Market, an easy walk up Concord Street along the water.

The natural same-day pairing is Fort Sumter. The ferry departs from the Fort Sumter Visitor Education Center at Liberty Square, 340 Concord Street, directly next door to the Aquarium and served by the same garage. The round trip runs about 2 hours 15 minutes, roughly 30 minutes of harbor crossing each way plus an hour at the fort. Book a morning ferry, then walk back to the Aquarium for the afternoon; one parking session covers both. Details, ferry times, and history are in our Fort Sumter guide.
