Visit Highlands Nature Sanctuary

At 2200 acres, the Sanctuary is the largest of the Arc’s preserves, and offers its most beautiful hiking trails. At the preserve’s heart is the sheer-walled limestone gorge of the Rocky Fork  in a region filled with rock formations, springs, and grottos. The preserve offers overnight lodging and the Appalachian Forest Museum (seasonal hours).

Visit Serpent Mound

The winding sinews stretching 1,348 feet, Serpent Mound is the largest and most internationally recognized of all the world’s ancient effigy mounds. The exact identity of the American Indians who constructed the mound is still a mystery, but their accomplishment still elicits a feeling of humility and awe in visitors today.

Visit Fort Hill

Fort Hill not only protects a 2000 year old large earthen-walled ceremonial enclosure on its flat ridgetop, but the 1400 acre preserve shelters one of the finest and oldest forests in Ohio. Eleven miles of  trails immerse hikers in the beauty of Ohio’s Appalachian hill-country, the remote trails shaded by towering trees. Interpretive Museum open seasonal hours.
