There has been a lapse in appropriations, and a shutdown of the federal government is currently in effect. Much of the C&O Canal National Historical Park remains open to the public, however, the National Park Service is not able to operate as normal. Visitor services, including park visitor centers and other NPS-staffed facilities, will not be available. Inquiries to the National Park Service will not be received or responded to until the shutdown ends.
The C&O Canal Trust’s staff are currently working remotely. Scheduled Trust events and Canal Quarters reservations will continue as scheduled. While a federal government shutdown is in effect, visitors should not expect services typically provided by the National Park Service to be available. All visitors are urged to practice safety in the park and plan ahead. Be a good park steward by recreating responsibly and practicing Leave No Trace principles, respecting cultural and natural resources.

When federal funding is restored, we look forward to continuing to work with our park partner to ensure the C&O Canal remains beautiful, safe, and welcoming for visitors today and for future generations.
