The Edisto River Canoe & Kayak Trail covers 66 miles of the river for which it's named. The Edisto is reputed to be the world's longest free-flowing "blackwater" stream. "Blackwater" is a term that not only describes the color of the tannin-rich water, but also refers to the peaceful rate of flow that characterizes such rivers.

A 24-mile motorcycle trail and a 26-mile horse trail are unusual features of Parsons Mountain Park in the Sumter National Forest.
