Parking Information
Trail Head at Potomac River
Drive to the end of Reilys Lock Road. There is a dirt parking lot where you can leave your car. Go up to the canal path and across the bridge over Seneca Creek. Take a right turn on a dirt road which leads to Tschiffely Mill Road. The Greenway Trail follows the road.
River Road
There are a few parking spaces on the shoulder of Seneca Road near the Greenway Trail sign. The trail goes from Tschiffely Mill Road, across Seneca Creek on River Road and up Seneca Road fifty feet or so to the Greenway Trail sign.
Berryville Road
There are a few parking spaces on the shoulder of the road where the road is next to the creek. A few more spaces are further south along the shoulder.
Berryville Road Side Trail
The side trail comes out at a sharp bend in the road where the woods ends and a field begins. This is about 1.6 miles down Berryville Road from Route 28. There is a wide grassy shoulder where one may park.
Route 28
There is a parking lot on the right side of the road (heading NW) just before crossing the bridge.
Black Rock Mill
There is a parking lot at Black Rock Mill. Also a few cars can park on the dirt shoulder where the trail comes out on the right (heading north). The Greenway Trail sign marks that spot.
Route 118
Not a good place to park. The shoulders are narrow and the traffic is fast. Maintenance workers may park on the right after crossing the bridge (heading south). Stay on the right shoulder when walking to and from the trail because there is no shoulder on the left.
Riffle Ford Road
Park on the wide shoulder where the trail comes out on the right (heading south) just before the creek. The trail starts behind the red metal gate.
Clopper Road
Drive to the Seneca Creek State Park Office. A side trail to the Greenway Trail starts at the end of the parking lot. Stop at the Office (formally the Visitor's Center) for a park map. (Note: there is no fee to go to the Park Office)
Route 355
Heading north on 355, there is a parking lot on the right just across the bridge over Seneca Creek.
