A few days ago I did my first walk along following the Appalachian Trail from Harper's Ferry into Maryland. I only had a few hours to burn so I only had time to follow the trail along the remainder of the C&O canal until it turned up into the hills.
The trail is wide gravel and very flat. The views are nice, as the trail runs between the Potomac and the C&O canal. Past the canal is a functioning set of railroad tracks.
C&O looking almost operational here. In some other spots there was no apparent water making it through though. Closer to Harper's Ferry there are remnants of a couple of locks.
The hike runs under this bridge - I believe it is the underside of the 340 bridge crossing from Maryland to Virginia.
The end of the walk approaching the bridge back into Harper's Ferry.
