Hiker-Biker campsites can fix a maximum of five to ten tents, depending on the campsite. Please refer to signage at the campsite for specific details. Do not tie ropes to trees and structures. The use of hammocks at the Chesapeake & Ohio Canal NHP is permitted at designated hiker-biker campsites and within campgrounds where reservations are required. If attaching to trees, hammocks must have straps that are at least one inch wide. Plastic zip cords, nails or screws are not permitted for the purpose of anchoring a hammock.
