Millersylvania State Park

Millersylvania State Park is an 842-acre camping park with 3,300-feet of freshwater shoreline on Deep Lake. The park, filled with trails, is abundant in old-growth Cedar and Fir trees. Millersylvania was constructed almost entirely by hand in 1935 by the Civilian Conservation Corps. Deep Lake, located on the property, attracts boaters, swimmers and fishermen. The state capital is a few miles north of the park.
