HRock Creek Loop, a 10-mile hiking-only loop, crosses through 3 management areas; The Big South Fork, Pickett State Park, and The Daniel Boone National Forest. Rock Creek is one of Kentucky's longest trout streams and is designated a Kentucky Wild River. Hikers also travel partly on the Sheltowee Trace and the John Muir Trail. While Rock Creek is picturesque, it presents a challenge to cross in high water. Mark Branch Falls is not on the Rock Creek Loop and is a guaranteed foot washer. I forgot my camera on this overnighter, but luckily John Thompson brought a camera and was the official trail photographer.
