The following is an interactive Google map. The walk begins at the Great Falls Parking area across from Anglers Inn and heads northwest along the C&O Canal Towpath tracing the Potomac River. It's nearly all an excellent, hard-packed, 10-ft wide flat trail to Harpers Ferry where the Potomac merges with the Shenandoah River. There, in the dark, you carefully approach and cross a footbridge to shortly after end the walk. The beginning and ending points have been modified because of logistic issues. The current estimate for the walk is a 50 miles. BTW - there is no clear record of where RFK ended his walk in Harper's Ferry. His starting point was said to be Great Falls Tavern.
