Black Rock Mill
Black Rock Mill is located right at the middle of Seneca State Park and Greenway Trail. It is a good place for exploration. There are barely any urbanized amenities for several miles in either direction of the Mill. Lake Clopper is more than five miles north while the Visitor Center is roughly six miles away. The Chesapeake and Ohio Canal is 7.2 miles long and runs south. You can also see a few houses and only a few people visit this area since the Greenway trail is relatively new.
The mill is adjacent to Black Rock Road
