Start your adventure at the parking lot for Congaree National Park and make your way to the Harry Hampton Visitor Center. There you can find clean bathrooms, drinking fountains, a gift shop, and trail guides. When you're ready to begin your hike, begin on the boardwalk and follow the signs for the River Trail - a 10-mile loop (with some overlap). The trail is clearly marked with signs along the way even though the path is narrow and overgrown in places. The trail will lead you to the Congaree River, but don't expect to be hiking along the river the entire trek. There is lots of foliage and wildlife along the trail and its longer length made it less populous and busy than some of the other trails in the park. Because the majority of Congaree National Park lies within a floodplain, the terrain is primarily flat with only slight elevation changes.
