The Mount Vernon Trail is a lengthy paved greenway trail running through the Washington DC metro area.
This trail is extremely popular with road cyclists (both recreationally and for commuting), but walkers/hikers, runners, skaters, and more all use this trail. This 18-mile trail runs along the banks of the Potomac River, providing gorgeous views of the river and a welcome respite from the press of traffic and the hustle and bustle of DC.
While the route shown here measures 18.6 miles one-way, you can tailor this distance as you see fit.
If you ride an out-and-back, you can easily get to 37 miles, and if you connect to other nearby greenway paths, you can go much, much further.
Or, if you want to hike a short way, you can do that too, beginning from any number of parks and access points along the trail.
