Swains Lock Hiker/Biker Campsite

What sets Swains Lock Hiker/Biker Campsite apart is its serene riverside setting along the Potomac River and its strategic location directly on the historic C&O Canal Towpath. This compact campground delivers a rare combination of easy access, history, and natural beauty, making it a prime destination for hikers, bikers, and minimalist campers seeking a peaceful overnight stop close to the Washington, D.C. metropolitan area.

Located at Mile 16.6 of the Chesapeake & Ohio Canal National Historical Park in Potomac, Maryland, the campground provides five designated tent sites, each equipped with a picnic table, grill, and access to a portable toilet for basic needs. While there are no electric hookups or potable water on-site, campers can access iodine-treated water from a hand-pumped spigot from mid-April to mid-November, though purification equipment may be necessary. The sites, set along the towpath, offer views of the lush, wooded surroundings and the gently flowing Potomac River.

Swains Lock’s proximity to major attractions enhances its appeal. The breathtaking Great Falls of the Potomac is less than three miles away, offering incredible hiking opportunities, such as the Billy Goat Trail. For those interested in history, the nearby Lockhouse 21 provides a glimpse into the canal's heritage. This rustic, first-come-first-serve campsite is ideal for short stopovers or day trips, particularly for cyclists and hikers exploring the park’s 184.5-mile towpath.
