Washington & Old Dominion Trail

Route Overview

The Washington and Old Dominion Trail—almost always called the W&OD—is one of the Mid-Atlantic's flagship rail-trails and a backbone of Northern Virginia's bike network. NOVA Parks maintains roughly 45 miles of paved multi-use path from Shirlington in Arlington County west to Purcellville in Loudoun County, following the former Washington and Old Dominion Railroad corridor through Falls Church, Vienna, Reston, Herndon, Sterling, Leesburg, and a string of smaller communities.

The trail surface is asphalt, generally about 10 feet wide, with half-mile markers, interpretive signs, and frequent road crossings as it moves from dense suburban corridors to rolling Piedmont farmland. A parallel 32-mile crushed-stone bridle path serves equestrians and off-road cyclists; the paved main trail is where most road and e-bike riders spend their time.

Elevation trends gently downhill from west to east, with Clarke's Gap near Leesburg marking one of the higher points. Most of the route reads as easy cruising, though western segments toward Purcellville add modest rolling hills. The W&OD connects to regional networks including the Custis Trail, Bluemont Junction Trail, and Four Mile Run Trail near Arlington, making it a natural choice for commuters, century-training loops, and family outings alike.

E-Bike Access and Rules

E-bikes are permitted on the W&OD Trail. NOVA Parks publishes explicit guidance on electric conveyances, and Friends of the W&OD Trail confirms that e-bikes and other approved e-devices may use the trail wherever traditional bicycles are allowed.

NOVA Parks defines an e-bike as a wheeled vehicle with operable pedals and an electric motor whose top powered speed is 20 mph—the same 20 mph cap referenced in Virginia Code for several micromobility devices. The authority states that devices capable of exceeding 20 mph under motor power must be limited to 20 mph while on the trail. Riders should treat that as an operational ceiling regardless of whether the bike is labeled Class 1, Class 2, or Class 3.

Virginia Code § 46.2-904.1 generally allows electric power-assisted bicycles wherever bicycles may ride on shared-use paths, subject to local or agency prohibitions. NOVA Parks notes that, as a matter of state law, it cannot adopt rules that conflict with Commonwealth statutes on these devices; enforcement of reckless operation falls to local police. Gas-powered vehicles, dirt bikes, ATVs, and motorcycle-style throttle bikes are not permitted.

• Allowed: pedal-assist and throttle-assist e-bikes that meet Virginia's statutory definition, operated at no more than 20 mph under motor power on the trail.
• Prohibited: gas-powered motor vehicles, unlicensed mopeds, and devices that cannot meet the 20 mph operational limit while on the path.
• Courtesy expectations: yield to pedestrians and equestrians; obey posted hours (generally 5 a.m.–9 p.m. east of Herndon, dusk west of Herndon).

Trail Highlights

The W&OD rewards repeat visits because each jurisdiction along the corridor feels distinct. Near Shirlington and East Falls Church, the trail hums with Metro connections and rush-hour bike traffic. Through Vienna and Reston, park-like buffers and creek crossings break up the suburban grid. Farther west, Leesburg's historic downtown and Purcellville's depot district offer natural turnaround points with coffee, breweries, and bike shops.

Historic railroad infrastructure dots the route: restored depots, cabooses, and signage explaining the line that once hauled freight and passengers toward the Blue Ridge. NOVA Parks' headquarters and a popular rest stop in Ashburn make a convenient meeting point for group rides.

• 45 miles of continuous paved rail-trail—among the longest urban-suburban paths in the eastern United States.
• Connections to Custis, Bluemont Junction, and Four Mile Run trails for longer loop options.
• Half-mile markers and multiple town centers for flexible out-and-back or shuttle rides.
• Parallel 32-mile equestrian trail for gravel-oriented detours on mountain bikes.
• Year-round community use with more than two million visits annually.

Access and Parking

One of the W&OD's strengths is the number of entry points. NOVA Parks lists parking and access across Arlington, Fairfax, and Loudoun counties; you rarely need to ride the full 45 miles to enjoy the trail.

Shirlington access sits along South Four Mile Run Drive with on-street parking—convenient for Alexandria and Arlington riders but not ideal for overnight vehicle storage. Purcellville's eastern lot at Loudoun Valley High School offers weekend parking during the school year; Purcellville West on Hatcher Street provides a gravel lot closer to the western terminus. Between those endpoints, lots and street access in Vienna, Reston, Herndon, Sterling, Ashburn, and Leesburg let you tailor distance to fitness and schedule.

For e-bike riders planning shuttle rides, the W&OD's mile markers simplify logistics: pick two parking areas with a known mile difference, ride one direction, and arrange a pickup. Capital Bikeshare and Metro do not serve the full length, but East Falls Church and other Orange and Silver Line stations sit within a short ride of eastern segments.

Riding Tips for E-Bikers

The W&OD is legal for e-bikes, but crowded segments demand restraint. Weekday rush hours around Shirlington, the Rosslyn approach paths, and town centers can feel as congested as any urban bike lane. Drop to a lower assist mode early, announce passes with a bell or voice, and resist using throttle-only acceleration where pedestrians queue at crossings.

Road crossings are frequent and vary in visibility. Some have actuated signals or dedicated crossing phases; others require a full stop and careful creep. E-bike torque makes it easy to jump into cross traffic—treat every driveway and side street as a potential conflict.

Bring lights for tunnels and underpasses, especially on late-afternoon return legs. The western trail beyond Herndon follows dusk closing rules rather than the fixed 9 p.m. cutoff used closer to Arlington. Carry water in summer; shade gaps widen in Loudoun's open farmland.

• Cap motor-assisted speed at 20 mph on the trail per NOVA Parks guidance.
• Use Eco or Tour assist in congested zones; save higher assist for open western rollers.
• Hybrid or endurance tires suit the paved surface; gravel bridle path needs wider rubber.
• Check novaparks.com for construction alerts—the Sterling Boulevard overpass project runs through 2028.

Seasonal Notes

The W&OD operates year-round, but each season reshapes the experience. Spring brings cherry blossoms and heavy weekend use; summer heat and thunderstorms push many riders to dawn or dusk slots. Fall color along creek valleys makes October prime for photography rides. Winter ice and leaf-covered pavement under bridges create slick patches—e-bike riders should reduce assist and avoid hard braking on shaded segments.

NOVA Parks posts active alerts for tree work, trail closures south of Edison Street in Arlington, and Dominion Energy maintenance between Sterling and Ashburn. Verify conditions before committing to a one-way shuttle ride in winter or during storm cleanup.

Nearby Trails and Resources

Eastern connections include the Mount Vernon Trail via Alexandria and Potomac bridges, though NPS rules differ from NOVA Parks. The Custis Trail links toward Rosslyn and the I-66 corridor. West of Purcellville, road routes reach the Virginia countryside and, with planning, the Winchester area.

For policy context, read eBikeQuest guides on e-bike classes and Mid-Atlantic trail etiquette. Virginia's statewide defaults under § 46.2-904.1 apply on the W&OD, but the 20 mph operational cap and local police enforcement make courteous riding essential to preserving access.
