To get from the C&O Towpath across the river to Harpers Ferry, you have to walk across the pedestrian portion/causeway of the railroad bridge that crosses the Potomac there at Harpers Ferry. To access the pedestrian causeway, you must climb the spiral stairs on the Towpath side of the bridge. You'd likely need to unload your gear from your bike to carry them up the stairs.
