    Default Black Rock Creek and Historic Mill

    Seneca Creek State Park, Black Rock Mill

    Situated in the middle of Seneca State Park and the middle of the Greenway Trail, Black Rock Mill is a good place to start exploring. Unlike the northern end of the park and the trail, there are hardly any developed amenities for many miles in either direction of Black Rock Mill. Lake Clopper is over 5 miles north. The Visitor Center there is 6.2 miles distant. The C&O Canal, in the other direction, is 7.2 miles south. Other than bridges, and a few road crossings, there’s not much else made by man in-between. Running or hiking the trail definitely gives you a feeling of being out in the country. Neither suburban developments nor rural housing are yet visible from most of the sections of the trail described here. Few people frequent the area mostly because the Greenway trail is new but also because of the long out-and-back distances. Don’t let that stop you. Just turn around at a distance comfortable for you and you’ll have a nice run.

    The namesake mill is located right off Black Rock Rd. west of Darnestown. The site is one of Montgomery County’s nicer outdoor exhibits. Inside the walls of the now roofless old building, displays tell the history and some of the mill’s gearing machinery is preserved hanging, giving a sort of cut-away view of a milling operation. A steady supply of water used to be supplied by a dam that was located 200 ft. upsteam. The dam no longer exists and the startling high water marks on the inside of the walls show the magnitude of the floods that came over the last century.

    Rolling tree covered hills surround the banks of the Great Seneca Creek from the mill, northeast and southward. As of 2005, The Greenway Trail goes from Damascus Recreation Park to the C&O Canal and will one day bridge the Potomac and Patuxent rivers. An additional access to areas south of Black Rock Mill can be gained by parking near the bridge at Darnestown Rd., Rte. 28. The trail northeast of here is described in the route description below.

    Going south from Black Rock Mill on the Greenway Trail it is 1.1 miles to Rte. 28 and is a little hilly. After ups and downs in the woods, it crosses along the edge of a farm field where large herds of deer can be seen. Beyond Rte. 28, the next four-and-a half miles are fairly flat, mostly shaded and very runnable until reaching Berryville Rd. Between Berryville Rd. and the Seneca Rd., the next 1.4 miles begins with a tributary creek crossing and an initial steep hill that is followed by successively easier ones. A final flat straight stretch of 0.75 miles on the road leads to the C&O Canal and Potomac River at Riley’s Lock and the mouth of the Great Seneca Creek.

    from 270, take route 118 (germantown rd) west towards germantown
    continue thru town approx 4 miles
    turn right on Black Rock rd
    mill parking is on the right after 1.25 miles.
