From end to end I believe it's about 9 miles. However, at the Simpsonville end parking lot they have mile 1 marked on the trail and at the Easley end they have 8.5 mile marked. I believe the trail extends a bit past the parking lots on both ends.
We visited last weekend. The trail map indicates that, from the parking area, it is 7.5mi in one direction and 1mi in the other direction.
