Congaree National Park

Log in to track your visit to Congaree National Park.

Congaree National Park is South Carolina's only national park and one of the most underrated in the entire system. Established in 2003 after decades of conservation advocacy that saved it from logging, Congaree protects 26,000 acres of the largest intact expanse of old-growth bottomland hardwood forest remaining in the southeastern United States. The park sits in a floodplain where the Congaree and Wateree Rivers periodically overflow their banks, depositing rich sediment that has allowed trees to grow to extraordinary size over centuries. More than 20 state and national tree height champions grow here — loblolly pines, bald cypresses, water tupelos, and sweetgums that soar to heights rivaling the ancient forests of the Pacific Northwest. The forest floor, when not underwater, is a cathedral of moss-draped buttressed trunks, tangles of knees from bald cypress trees projecting above the mud, and a dense understory alive with red-shouldered hawks, river otters, and wild pigs. In May and June, Congaree hosts one of the world's most spectacular light shows: synchronized fireflies that pulse their bioluminescent signals in coordinated waves across the forest — a phenomenon so rare and so beautiful that the NPS runs a lottery for timed-entry tickets to witness it. For a park that sees fewer visitors in an entire year than Yellowstone sees in a week, Congaree offers an experience utterly unlike anything else in the Southeast.

The 2.4-mile Boardwalk Loop is the gateway to Congaree, elevating visitors above the floodplain floor through the heart of the old-growth forest with minimal physical demand — it's accessible, flat, and extraordinary. The sturdy boardwalk winds past massive loblolly pines, towering bald cypresses rising from dark water, and dense colonies of cypress knees. The Weston Lake Loop (4.4 miles) extends deeper into the forest to a reflective oxbow lake where wood storks and anhingas fish from overhanging branches. Cedar Creek, a slow blackwater creek stained dark with tannins from fallen leaves, is Congaree's premier paddling route — kayak or canoe the 15-mile loop through the forest interior for an unforgettable multi-hour journey. Canoe rentals are available from local outfitters in Columbia. Birding is exceptional year-round: the park has recorded over 200 species, including the increasingly rare Swainson's warbler, prothonotary warbler, and barred owl. Ranger-led firefly programs during May and June are booked through a lottery on Recreation.gov.

Congaree supports one of the highest concentrations of bird species in the Southeast, making it a must-visit for birders. Barred owls are heard calling ("who cooks for you, who cooks for you-all") throughout the day. Prothonotary warblers — brilliant golden-yellow — nest in tree cavities along Cedar Creek each spring. River otters are present but secretive; kayakers are the most likely to spot them. White-tailed deer, feral hogs, and bobcats roam the forest floor. The park's periodic flooding creates a rich aquatic habitat supporting bowfin, redbreast sunfish, and river cooter turtles.

There is no entrance fee for Congaree National Park. The Harry Hampton Visitor Center off Old Bluff Road is the starting point for all hiking and ranger programs. The park's floodplain floods several times per year — check current conditions on the NPS website before visiting, as the boardwalk may be partially submerged. Longleaf Campground (primitive, 10 sites) and Bluff Campground (primitive, 7 sites) are free but require a free permit from the visitor center. The synchronized firefly lottery opens in April for May/June events; competition is intense. Spring and fall are the best seasons; summer is extremely hot and humid.

Congaree is 20 miles southeast of Columbia, South Carolina, via SC-48 (Bluff Road). From Columbia, take I-77 south to exit 5, then SC-48 east for about 12 miles to Old Bluff Road. Columbia Metropolitan Airport (CAE) is the nearest commercial airport, about 25 miles from the park. Charlotte Douglas International (CLT) is 90 miles north. There is no public transit to the park.

Check the park's flood gauge online before you visit — Congaree floods roughly 10 times per year, and the boardwalk can be knee-deep in murky water. Mosquitoes are intense from May through September; bring strong repellent and wear long sleeves. The blackwater creeks look dark but are not polluted — the color comes from leaf tannins, like tea. Sunscreen and insect repellent both wash off in the water, so plan your paddle accordingly. The firefly program is genuinely bucket-list; enter the lottery the moment it opens.
