Rock Mill Park encompasses the historic Rock Mill, a stunning grist mill built in 1824 above the Hocking River Falls and the scenic Rock Mill Covered Bridge, constructed in 1901. Standing 90 feet above the gorge of the falls, Rock Mill stands as a testament to the rich agricultural heritage of Fairfield County, whose “fair fields” attracted so many brave pioneers in the late eighteenth and early nineteenth centuries. In the early 1800s Rock Mill was one of a dozen mills in the area whose power source was the Hocking River. The mill was in operation grinding flour and corn into wheat and meal as late at 1905. This park opens at sunrise and closes at sunset. The mill is open to visitors Saturday and Sunday, 1:00pm-3:00pm from May-October.
