Photo #5473 - Cedar Falls-Hocking Hills State Park Hiking and picnic area at Hocking Hills State Park. Waterfalls, massive hemlocks, interpretive signs and huge rock formations along 1/2 mile trail. Cedar Falls has is one of the largest waterfalls in the Hocking Hills Region. Visitors can expect to see moss-covered cliffs, a rugged trail and maybe the remnants of a grist mill that was built above the falls in the mid-1800's.
