Context for the broader area surrounding Leopards Mill Hiker-Biker Overnight (Hbo) Campsite, sourced from the federal Recreation.gov rec-area record.
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 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.

Best season: spring. Spring offers the best combination of mild weather, active wildlife, and blooming river-edge flora — expect daytime highs in the mid-50s to mid-70s F (April–May) with cool nights. The towpath and campsite are lively with migrating birds, wildflowers, and comfortable conditions for hiking, biking, and paddling before summer humidity peaks; crowd levels are moderate (weekends busiest) so weekday trips feel very peaceful. Note that spring can include muddy sections of the towpath and higher Potomac Peak months: April, May, October, September Avoid: January, February
Spring cited as most comfortable: mid-50s to mid-70s, wildflowers and active migrant birds.
