01Congaree NP · Boardwalk Loop · Weston Lake · Visitor Center
Day 1 walks into the largest remaining tract of old-growth bottomland hardwood forest in the United States — and the walk is almost absurdly easy. The Boardwalk Loop runs 2.4 miles on elevated planks through the floodplain: flat, bench-lined, and accessible, winding past loblolly pines and bald cypress that rank among the tallest trees in eastern North America. Start at the Harry Hampton Visitor Center (free, check the famous mosquito meter by the door), walk the loop counter-clockwise, and take the Weston Lake spur halfway round — the overlook puts you eye-level with the canopy.
Morning: the loop, slowly
Two hours, minimum, for 2.4 miles — this is a looking walk, not a hiking walk. The numbered markers match the free trail guide: champion trees, cypress knees, the high-water marks from past floods. Kids love the knees; grandparents love the benches.
Afternoon: rest in Columbia
Drive the 30 minutes back to Columbia and rest — the floodplain rewards fresh legs, and the afternoons here run warm. Pool time, naps, no agenda.
Evening: dinner in the Vista
Dinner in Columbia's Vista district: Motor Supply Co. (farm-to-table, the local special-occasion pick) or Pawley's Front Porch for burgers the kids will actually eat.
Where to stay
Columbia for all three nights — the park is an easy 30-minute drive, so one base does the whole trip. Hotel Trundle is the quirky, design-led downtown stay; Graduate Columbia leans collegiate-fun near the university. Both keep you close to dinner.
Good to know
The park is free — no entrance fee, no timed entry. The visitor center keeps standard daytime hours; the grounds stay open.

Walk it counter-clockwise. The Boardwalk Loop's best light and quietest stretches run counter-clockwise in the morning — you'll hit Weston Lake just as the mist burns off, and you'll be back at the visitor center before the afternoon heat.
