Trails ranked today
Pyrite Mine Loop
Loop through mature Piedmont forest to the ruins of the Cabin Branch Pyrite Mine — concrete foundations, an interpretive sign, and quiet woods. Good rainy-day pick when the river-trail crowds chase shelter.
Quantico Cascades
Out-and-back to a small rock cascade on the North Fork Quantico Creek — modest, more riffle than waterfall. The longest and most remote-feeling trail in Prince William Forest.
