Yesterday, we kept our trail running habit going by doing a 7 mile loop in Prince William Forest. The loop was inspired by this LocalHikes entry, though there's no official "Pyrite Mine Loop" as the trail title suggests. Instead, I handed the map to Shira, and had her navigate us through the woods.
It's been years since we've been to Prince William Forest, but it continues to be a real gem. The trails are well marked, and well maintained. It's hard to believe how close 'real hiking' is to DC.
Here are some photos I snapped along our run. The ones of the concrete foundation are of the "Pyrite Mine." Yeah, you need to use your imagination see that a mine was once there. The terrain was especially muddy in some places, but nothing we couldn't handle.
