Our Partners

The Chesapeake and Ohio Canal National Historical Park encourages visitors to help preserve, protect, and enjoy the resources of the park. Various volunteer programs are available for the public to be very involved in park living history, maintenance, or ranger programs.

Many outside organizations throughout the area work to support the park.

C&O Canal Trust

The C&O Canal Trust was founded in 2007 as the official nonprofit partner of the C&O Canal National Historical Park. As the Park’s official “Friends Group,” the C&O Canal Trust is committed to raising funds and resources to provide a margin of excellence for the Park and to enhance the visitor experience. We provide opportunities for real and meaningful engagement to people of all ages, means, and abilities through philanthropy, volunteer opportunities, interpretive and education programs, and advocacy. We also play a leadership and supportive role in connecting the Park with its neighboring communities and other organizations throughout the region. Contact:

The Friends of Historic Great Falls Tavern

The Friends of Historic Great Falls Tavern is an all-volunteer nonprofit organization founded in 1973. Its primary mission is to support the National Park Service at the C & O Canal National Historical Park in maintaining and preserving the Historic Great Falls Tavern Visitor Center and its surrounding area. In addition, the Friends support ongoing preservation efforts of the C & O Canal and numerous historic structures along its entire length. This support is provided through both volunteer time and financial resources.

The Friends also hold social events to foster camaraderie and sharing of knowledge about the Historic Great Falls Tavern and the C&O Canal. These activities include an annual trip to a Canal-related historical location, a summer picnic with the C&O Canal Association, British-style pub quizzes, and an annual dinner with a presentation on some aspect of the Canal or local history.

C&O Canal Association

The Chesapeake and Ohio Canal Association was founded in 1954 by the conservationists and supporters who participated in the hike that year led by Supreme Court Justice William O. Douglas. In the early years, the Association took the lead in the campaign that lead to the creation of the C&O Canal National Historical Park in 1971.

Today, we remain an independent, all-volunteer organization of citizens concerned with the continued viability of the Park and all of its natural and historic resources. To help preserve and protect these resources, we readily assist the Park Service with both manpower and money. Additionally, we monitor conditions (both regulatory and physical) that could adversely affect the Park. We work to bring attention to these conditions and openly advocate on behalf of the Park.

We lead and/or sponsor hikes, bike trips, paddle trips in the canal and river and nature walks to investigate trees, flowers, birds, insects and geology in an effort to educate participants and bring attention to the Park.

Membership in the C&O Canal Association is open anyone with an interest in the C&O Canal and the Potomac River. Contact:
