16. Scott's Run

Directions: Scott's Run is located just beyond the Beltway: take Beltway exit 13 in McLean, go west on Georgetown Pike (193), and in a few hundred yards, turn right into the first parking lot (there will be a sign), or go to the bottom of the hill and turn right into the lower parking lot, across from Swink's Mill Road, and alongside Scott's Run. Good maps are on Hiking Upward. Good background information about Scott's Run here and here.
