Black Hill Regional Park is a 1300-acre, lake-oriented park that features the mostly hard-surface 4.6 mile Black Hill Trail, over 16 miles of natural surface trails, and a water trail on Little Seneca Lake. Trails offer spectacular views of the lake, and meander through oak and hickory forests through some of our Best Natural Areas. Historical markers identify former mill sites and interpret past gold mining history. Unless noted otherwise on the map, trails marked “Natural Surface” and “Hard Surface” are “Shared by All” trails which includes hikers, bikers and equestrians.
