Harpers Ferry, WV, has a small historic district which presents a real parking challenge. The Park Service provides a great shuttle from the Visitors Center, on the top of the hill a mile or two away from the historic district, right into the heart of things and on a continuous loop. The shuttle buses have a 2-bike rack on the front, so that my husband and I were able to ride from parking ($10/day) at the Visitors Center down into town. We were told we weren't allowed to ride bikes down the hill on the main road into town (?? don't know why??). But it was a good way to go as we would not have wanted to ride up that hill to return to our car at the end of the day! The main street of the town was all museums--well done and lots of rangers and park people to help and answer questions. Also park employees dressed up in period costumes to help present the period of Harpers Ferry's important years in our country's history. The side streets going up the hill have lots of shops and, cafes and ice cream places.
