Tucked away in a pocket of woods near Potomac, MD, are several miles of trails of all varieties — from flat-as-a-pancake towpath to rocky-as-hell singletrack. The route described here is basic loop on the rolling Valley, Gold Mine, Overlook, and Woodland Trails. Along the way you will pass by the Maryland Mine ruins, where gold was processed from 1867 to 1939, and the historic Great Falls Tavern Visitor Center.
For additional miles, explore other spurs and trails criss-crossing the loop. Or extend the loop onto Berma Road and the C&O Canal Towpath, both of which are excellent for a mid-run tempo effort. If technical trails are what you seek, then cross over to any of the three sections of the notoriously rocky Billy Goat Trail. Download the printable map and explore.
If parking is tight at Old Anlgers Inn, drive to nearby Carderock and run up the C&O Canal towpath to Old Anlgers, which will provide a nice 1.5 mile warm-up and cool-down to your run.
