Congaree National Park
Boardwalks, paddling routes, champion trees, sloughs, and floodplain forest protect one of the largest remaining expanses of old-growth bottomland hardwoods in the Southeast.

Congaree protects an exceptional remnant of old-growth bottomland hardwood forest shaped by a moving river. Floodwater deposits sediment and nutrients, replenishes sloughs, and sorts tree communities across slight changes in elevation. Champion trees are impressive, but cavities, fallen timber, layered canopy, and slow decay reveal the forest’s deeper continuity.
The elevated loop offers the clearest introduction to this floodplain system, especially when attention shifts between dry ridges and low, water-holding ground. Because river levels can transform trails and paddling routes, consult the gauge and current notices before setting out. Heat, insects, mud, and submerged paths are part of the living landscape rather than signs of neglect.

Quick guide
- Best first route
- The boardwalk loop introduces floodplain structure without requiring backcountry navigation.
- After flooding
- Conditions may improve for paddling while closing or obscuring walking routes.
Let floodwater explain the forest
- Begin at water level
- Check current flooding before choosing boardwalk, canoe, or backcountry routes.
- Read micro-elevation
- Small height differences determine where water lingers and which trees dominate.
- Listen for old growth
- Canopy structure, fallen wood, cavities, and slow decay matter more than finding one champion tree.
- Expect a wet forest
- Mud, mosquitoes, heat, and submerged trail are ecological conditions, not maintenance failures.
Good to know
Read the current river gauge first; it determines whether water, mud, or dry forest will define the day.
