Turkey Run Trail

This medium-difficulty outing sits inside Turkey Run Park (National Park Service) along the Potomac Gorge in McLean, Virginia, with a rugged, creek-and-river feel that’s surprisingly wild for how close it is to Washington, DC. Expect a mix of narrow dirt singletrack, short scrambly bits, streamside rock, and a few steep stair/step sections that concentrate most of the effort into a couple of climbs rather than a steady grind.

Getting to the start (car + public transport options)

Start point landmark (nearest known address / place):
Aim for Turkey Run Park, George Washington Memorial Parkway, McLean, VA 22101 (park entrance and picnic/parking areas). This is the most reliable “destination” to plug into navigation, and it puts you at the correct park unit for the trail system. (nps.gov)

By car - From I‑495 (Capital Beltway), use Exit 43 to the George Washington Memorial Parkway, then take the signed exit for Turkey Run Park. (nps.gov)
- Parking is spread across several picnic areas (often referenced as C‑1 / C‑2 / B / A on park mapping). (nps.gov)

By public transport (practical approach) - There isn’t a direct “drop-off at the trailhead” transit stop inside the park. The workable strategy is: Metro into the McLean/Tysons area, then use a rideshare/taxi to Turkey Run Park’s entrance on the George Washington Memorial Parkway. Plan for the last mile(s) to be vehicle-based—walking in along the parkway is not a pleasant or safe substitute. - If you’re already on foot via the larger corridor, Turkey Run Park is connected by the Potomac Heritage Trail, roughly 2 miles (3.2 km) south of the American Legion Bridge and about 4 miles (6.4 km) north of Fort Marcy.

Route character, distance, and climbing (what “12 km / 400 m” feels like here)

You noted ~12 km (7.5 mi) and ~400 m (1,312 ft) of gain. In this park, elevation tends to come in punchy, repeated ups/downs: short steep drops to water level, then climbs back to the upland benches. Even on shorter mapped loops, hikers often feel the effort because the steepest grades are concentrated into staircases, switchbacks, and ravine edges rather than spread evenly. The most common “signature” loop here pairs the Turkey Run Trail with the Potomac Heritage Trail for a shorter moderate circuit; extending it to ~12 km typically means adding extra out-and-back along the Potomac Heritage Trail and/or stacking additional internal connectors where allowed.

For navigation, download the route in HiiKER before you arrive and keep it handy at junctions—this trail network has multiple intersections and it’s easy to drift onto a connector if you’re chatting or moving fast.

What you’ll see along the way (landmarks + terrain)

• Potomac River overlooks and shoreline access: You’ll get periodic openings to the river—small rocky “beach” areas and ledges where you can look across the Potomac. These spots are great for a breather, but they can be slick with algae or wet leaves after rain.
• Turkey Run stream crossings: The route commonly crosses Turkey Run (the creek) on bridges/stepping points. After storms, water can rise quickly and make rocks
