Designation: National Historical Park
Location: District of Columbia, Maryland, West Virginia
Preserving America's early transportation history, the C&O Canal began as a dream of passage to Western wealth. Operating for nearly 100 years the canal was a lifeline for communities along the Potomac River as coal, lumber, and agricultural products floated down the waterway to market. Today it endures as a pathway for discovering historical, natural, and recreational treasures.
The Washington, DC, area has a four-season Mid-Atlantic climate. Summertime is warm and humid, while winter can be cold and snowy. Precipitation averages 2-4â monthly, year-round. The climate gradually gets cooler and wetter further west along the canal where the elevation is higher.
The park has numerous access points. There is no main entrance. In Washington, DC, the C&O Canal begins in Georgetown on 29th Street NW, south of M Street, and runs alongside Canal Road / Clara Barton Parkway out of DC to the west. The entrance to Great Falls is at Canal Road and MacArthur Blvd in Potomac, MD. Park Headquarters and the Williamsport Visitor Center are located off I-81 at exit 2. Cumberland Visitor Center is off I-68 at exit 43C. See the maps page for more.
The area of Great Falls is one of the reasons for the C&O Canal needed to be built for boat traffic.
