The Main Stem of the Potomac River: Green Spring to Harper's Ferry, WV Professional Review and Guide
"From 2 miles below Green Spring, West Virginia (Oldtown, Maryland), where the North and South Branch of the Potomac meet to form the great Potomac River, the beautiful, historic West Virginia-Maryland border river flows majestically for almost 115 miles toward Harper’s Ferry. The river is mostly wide, flat water, but there are occasional Class 1–2 riverwide rapids. In most places it’s suitable for well-coached beginners in open boats. It gets dangerous in high water for paddlers with marginal skills.
The historic C&O Canal follows the river along the Maryland shore. A well-maintained hiking and cycling trail follows the old canal towpath. The National Park Service manages the Canal as a National Historic Park. There are a number of historic or restored remains are worth visiting. Civil War battlefields and Revolutionary War sites add further interest to canoe runs in this area. There are several developed campsites along the river, to use as a base."
