The park contains some of the tallest loblolly pines in the world, with some reaching heights exceeding 167 feet.
It is one of the few places in North America where visitors can experience the synchronous firefly phenomenon, typically occurring in late spring.
The park's boardwalk was built specifically to minimize foot traffic damage to the sensitive forest floor and root systems.
Congaree is an International Dark Sky Park, offering minimal light pollution for stargazing.
The park features 'knees,' which are woody projections growing vertically from the roots of bald cypress and water tupelo trees.
Unlike many national parks, Congaree does not have entry fees for general access.
The forest serves as a natural flood-control mechanism, absorbing massive amounts of water during heavy rains in the Midlands region of South Carolina.
Several trees in the park are estimated to be over 500 years old.
Congaree National Park protects the largest intact expanse of old-growth bottomland hardwood forest remaining in the southeastern United States. The park sits within the floodplain of the Congaree and Wateree Rivers, resulting in a complex ecosystem of nutrient-rich alluvial soil. It features a 2.4-mile elevated boardwalk loop that provides accessible passage through the swamp environment. Visitors can navigate Cedar Creek via canoe or kayak to observe the park's biodiversity from the water. The area is noted for its record-breaking tree heights, including several species of champion trees that reach over 160 feet. It is designated as a Globally Important Bird Area and serves as a vital habitat for migratory species. The forest floor is subject to periodic flooding, which shapes the topography and tree growth patterns. It holds the status of a UNESCO Biosphere Reserve due to its ecological significance.

Bring EPA-registered insect repellent, as mosquitoes can be dense in the swamp environment.
Check the park's flood gauge status on their official website before arriving, as high water levels can close trails.
Pack binoculars for wildlife viewing, specifically for spotting pileated woodpeckers and barred owls.
Attempting to hike off-trail in the backcountry without proper navigation tools or experience in marshy terrain.
Practice Leave No Trace principles; keep voices low to avoid disturbing wildlife; stay on the boardwalk to protect fragile vegetation.
