Embark on a moderate touring cycling adventure along the Chesapeake and Ohio Canal Towpath, a 39.0 miles (62.8 km) route that winds beside the Potomac River. You will experience a lush 'tunnel of trees' and predominantly dirt and gravel terrain, offering a varied ride with 306 feet (93 metres) of elevation gain. This journey takes approximately 4 hours and 42 minutes to complete, leading you past historic features like the impressive Monocacy Aqueduct, which carries the canal over the Monocacy River.

When planning your visit, be aware that the towpath's surface can be varied, with rough patches, mud, and roots, especially after rain. For this reason, road bikes with skinny tires are not recommended; gravel, hybrid, or mountain bikes with tires 32mm or wider are better suited for the trail. You will find numerous free hiker-biker campsites along the way, equipped with piped drinking water and portable toilets at frequent intervals.

The Chesapeake and Ohio Canal Towpath offers a unique journey along a historic waterway, allowing you to encounter hundreds of original historic features like locks, lock houses, and aqueducts. These structures serve as reminders of the canal's past, providing a rich historical context to your ride. The route follows the Potomac River, immersing you in a natural setting while tracing the path of this significant piece of American history.

Embark on a truly epic touring cycling adventure with the Monocacy Aqueduct – Horseshoe Bend at Great Falls loop from Barnesville, a route that promises a rich tapestry of historical landmarks and breathtaking natural beauty. You'll pedal along the historic C&O Canal Towpath, where the impressive Monocacy Aqueduct stands as a testament to early engineering, often enveloped by a verdant canopy. Further along, the route plunges into the dramatic landscapes of Great Falls Park, offering stunning vistas of the Potomac River as it carves its way through Mather Gorge, culminating in the picturesque Horseshoe Bend. The terrain is a mix of hard-packed earth, crushed stone, and some paved sections, with challenging gravel paths and technical, rocky stretches within the park, making it a diverse and engaging ride.

This difficult 77.6-mile (124.9 km) loop, with its 1433 feet (437 metres) of elevation gain, is a full-day commitment, typically taking around 9 hours and 9 minutes to complete. An early start is crucial to maximize daylight, especially if you plan to explore the viewpoints at Great Falls. While parking is available in Barnesville, ensure your bike is suitable for varied surfaces, as some parts of the C&O Canal Towpath and Great Falls Park trails are unpaved and can be challenging for road tires. Always carry sufficient water and supplies for this extensive journey.

What truly sets this route apart is its unique blend of human ingenuity and raw natural power. The Monocacy Aqueduct, a marvel of 19th-century construction, offers a fascinating glimpse into the region's past, having narrowly escaped destruction during the Civil War. This historical context pairs beautifully with the powerful natural spectacle of the Great Falls of the Potomac, one of the most dramatic natural features in the Mid-Atlantic. The route provides an excellent opportunity to experience both the tranquil canal environment and the dynamic river landscape, making it one of the more popular routes for experienced cyclists seeking a comprehensive Maryland cycling experience.
