Congaree protects the largest intact stretch of old-growth bottomland hardwood forest left in the United States, a towering, cathedral-like floodplain forest of champion trees along the Congaree River in South Carolina. Fed by the river’s frequent floods, it is a lush, humid wilderness of soaring trunks and quiet water, best explored on a boardwalk stroll or a paddle beneath the canopy.
The park is a floodplain, not a swamp, the Congaree and Wateree rivers periodically spill across it, dropping nutrients that feed one of the tallest deciduous forests on Earth. Bald cypress with their knees, loblolly pines, oaks and sweetgums tower overhead, sloughs and oxbow lakes thread the forest floor, and the whole teems with birds, otters, deer, bobcats and, yes, snakes and alligators at the edges.
Fall through spring is the most comfortable time, avoiding the worst summer heat, humidity and mosquitoes, and the park’s famous synchronous fireflies draw crowds for a couple of weeks in late spring. Flooding can occur any time of year and is part of the ecosystem, so check conditions, as high water closes trails and the canoe route.
The park lies southeast of Columbia off SC-48, with the visitor center and the elevated boardwalk loop as the main access point. A vehicle gets you there; from the boardwalk, hiking trails and the Cedar Creek canoe trail lead deeper into the forest for those wanting more.
Walk the accessible boardwalk loop through the heart of the old growth, paddle the Cedar Creek canoe trail beneath the canopy, and hike longer forest trails for solitude. Ranger programs, birding, and, in season, the synchronous firefly display are highlights, all in a rare, towering forest.
Flooding is the defining variable, so always check whether the floodplain is inundated before you hike or paddle, and never underestimate rising water. Mosquitoes can be intense in the warm months, venomous snakes are present, and the flat, featureless backcountry makes it easy to lose your way. Carry a map, compass or GPS and plenty of water.
There is no entrance fee, but backcountry camping needs a free permit, and trails or the canoe trail may close with high water. This page is a general overview, not a live conditions report; always confirm current flood levels, conditions and closures with the National Park Service before your trip.
Set this declination on your compass, then align it to the map's north lines; it is the angle between true north and magnetic north, refreshed each year.
