Fairfax Underground
Welcome to Fairfax Underground, a project site designed to improve communication among residents of Fairfax County, VA. Feel free to post anything Northern Virginia residents would find interesting.
Areas along the Potomac River in the local parks; Also across the river in Maryland along the C&O Canal towpath, goes all the way to Cumberland, MD. Passes through some wilderness areas and national forestlands here and there.
there are some remote areas in Hemlock Overlook/Bull Run/Fountainhead parks but you can't get too terribly lost. short of driving a couple counties west, try some of the lesser traveled sections of Mason Neck State Park or Prince William Forest.
