From Hartwell, head north on GA-51 for 7 miles to the stop sign. Take a left onto Boleman Hill road and drive 2 miles. Head straight off of the corner of the turn and continue onto Paynes Creek road for 0.8 miles. You should start seeing signs for Paynes Creek campground/recreation area. Follow signs for the last couple of quick turns, and get ready to mountain bike!
