NPS Photo Want to spend a night under the stars at the C&O Canal? Then you've come to the right place! The C&O Canal is a 184.5 mile long linear park stretching between Washington, DC, and Cumberland, Maryland. It is about a 4 hour drive end to end. Well WaterWell water is generally available in across the park from mid-April (around the 15th) to mid-November (around the 15th).Since spring 2023, the well water in hiker-biker campsites have been signed non-potable. Water from wells at paid campgrounds remains potable and safe for drinking, cooking, or washing. This change occurred to ensure a more reliable water source for visitors in the park. Due to testing and treatment requirements, the park can maintain potable water in a targeted number of wells in fee campgrounds.
Winter Well Conditions: Typically around mid-November, water faucets in all camping areas throughout the park are turned off for the season. This gives the pipes a chance to dry out and prevents water inside the pipes from freezing, expanding, and causing the pipes to crack or burst in the cold. Campsites are still open to the public, but visitors should plan to bring their own water supply. Faucets are turned back on in the spring. Overnight ParkingParking overnight is allowed in designated parking areas anywhere in the park without a permit. If you choose to park overnight in the Washington, DC or Montgomery County, MD sections of the park, you should submit your license plate number, description of your car, and when you expect to return to copermitsoffice@nps.gov. If you park outside of Washington, DC and Montgomery County, you do not need to submit this information. TrashThis is a trash free park; take all trash away.
