C&O Canal Towpath and Capital Crescent Trail Cycling

The C&O Canal Towpath and the Capital Crescent Trail both begin in Georgetown, Washington, DC, near the Georgetown Visitor Center at 1057 Thomas Jefferson Street NW, and offer two car-free cycling routes into Maryland, in the United States. The Capital Crescent Trail is a paved former railway line running about 11 miles to Bethesda, passing through the Dalecarlia Tunnel and over the Rock Creek trestle. The C&O Canal towpath is an unpaved gravel and dirt route that follows the historic canal for about 14 miles to Great Falls, beside the river and old lock houses. Both are largely flat, with a gentle gradient, and the towpath rewards riders on hybrid or mountain bikes. Cyclists need basic fitness for a three- to five-hour outing and the ability to ride on loose surfaces on the towpath. There are no formal age limits, but young children should ride with an adult. The activity is self-guided, so riders bring their own bike or rent one from a shop such as Revolution Cycles at 3411 M Street NW, +1-202-965-3601, or use Capital Bikeshare. Recommended equipment includes a helmet, bike lights for the Dalecarlia Tunnel stretch, a repair kit and water, since services are limited between towns. There is no guide or formal safety briefing; riders should carry a phone, know their route, and call 911 for emergencies. Mile markers along the canal help with navigation. Costs are low: free on a personal bike and about $35 to $50 per day for a rental. The trails are open year-round, but spring and fall give the best weather and foliage. Conditions to avoid include the days after heavy rain, when the towpath is muddy and parts can flood, midsummer heat, and icy winter mornings. Weekend afternoons are busy near Georgetown and Bethesda, so early starts are advised. A typical outing takes three to five hours depending on distance, with options to pause at canal-side cafes and viewing points.
