A fantastic loop through the George Washington National Forest in Virginia.

From the TH for Turkey Pen trail, you will follow a jeep trail for about 1.5 miles, and then take a left, crossing a small stream onto the Mills Creek trail. For the next 9 miles or so the trail is mostly a single track climb. A lot of the climbing is easily runnable and almost flat. As you approach the Slacks trail and Bald Mountain you really start to climb, with nearly 1000 ft of gain in the last 1.5 miles.
