Just past Weverton lock, the Appalachian Trail merges with the C&O until
Lock 33 where the AT leaves the side of the Potomoc and goes into the town of Harpers
Ferry. If you'd like to pick up the AT here, follow the white blazes to the
parking lot and under highway 340. It will take you up to 1,250 feet elevation
in about a mile and a half. A very different kind of hike than the straight
and flat canal.
For more info on the Appalachian Trail, you could visit the
Appalachian Trail Conference's website
or Kathy Bilton's site. Whether you're interested in an overnight, a section,
or a though hike, you'll want to get a copy of the Appalachian Trail Thru-Hikers Companion. The AT headquarters is in the nearby town of Harpers Ferry and you can pick up a copy there. Harpers Ferry is approximately the halfway point between Spring Mountain in Georgia and Mount Katahdin in Maine, the AT endpoints.
You can enjoy this wonderful view of the Potomac from nearby Weverton Cliffs. To reach it, head north on the Appalachian Trail for about 20 - 30 minutes until you reach a turning point where two trails meet. To the west, the white blazes marks the continuation of the AT. To the east, the blue blazes leads you a short distance to this overlook.
