Singletrack that crosses the Appalachian trail. Would rate in a green trail with small climbs and descent at the end back down to Old Forge Road. Have a video on Youtube
Take Old Forge Road from Route 16 east of Waynesboro, PA. Go approximately 5 miles north to Camp Penn. Turn right onto Rattlesnake Run fire road, go about a 1/4 of a mile and Chickadee Snowmobile/Bike trail will be on your right.
