As you ride onto the wide canal bend, you’re met with serene water views—Widewater is a beautiful lake that serves as habitat for many bird and wildlife species. It’s an ideal spot to pause, do some birdwatching, and soak in the calm before continuing your journey along the Potomac and the Chesapeake & Ohio canal.

This towpath is as much about the journey as the destination. Cruise past historic locks, aqueducts, and shady woodlands along a trail with gentle grades and rich history. Pause at scenic river overlooks or old lockhouses for a quick rest.

Enjoy easy access to the Great Falls, a popular destination for photographers, hikers, and expert kayakers. Though not exceptionally tall, the falls surge with force as the Potomac River carves through ancient, metamorphic rock.

Built in 1837 by the Seneca Sandstone Company, this mill was created to process the distinctive red sandstone quarried nearby. Today, the ruins, easily spotted by their red sandstone walls, are accessible via the C&O Canal towpath and are especially visible during the winter months when vegetation is dormant.

Lock 21, aka Swains Lock, is a lock house and campsite. It was built in the 1830s and transported items such as grain and coal between Georgetown and Cumberland. It was named after the Swain family and John Swain, who helped build the canal, and Jesse Swain, the lockkeeper. The family lived here until 2006.

Lock 22, aka Pennyfield Lock, was built between 1829 and 1831, and the name came from the misspelling of the Pennifield family name. It has been restored and offers overnight stays to recreate the rustic feeling from that period.

Located at mile 14.3 on the C&O Canal Towpath in Potomac, Maryland, Great Falls Park is a must-visit highlight for hikers, cyclists, and history buffs alike. A short boardwalk leads to the Olmsted Island overlook, where the Potomac River dramatically crashes over jagged rocks—one of the most scenic views near D.C. For hikers, the popular Billy Goat Trail offers three segments, with Section A featuring challenging rock scrambles and breathtaking river views. The historic Great Falls Tavern, built in 1829, now serves as a visitor center and launch point for seasonal mule-drawn canal boat rides. The towpath itself is flat and easy to navigate, ideal for walking or biking. Amenities include restrooms, picnic spots, and interpretive exhibits. Parking is available at the visitor center (fee required), or you can park for free at nearby Swains Lock and walk or ride 2.5 miles to the falls.
