Obviously this map is not exactly correct, as I had to draw a line through the woods (but there is a road there). If you turn onto clarktown it will start going up pretty steeply. Then it will turn to gravel, still pretty steep. The gravel/dirt is apprx. 3 miles long and drops you out onto Fiddler's Branch (which connects to Simerly Creek). If you do it in reverse, the first bit of gravel is too loose and too steep to ride.
