Ohio's Largest Natural Bridge
Rockbridge State Nature Preserve protects a geological feature unlike anything else in Ohio: a natural sandstone arch spanning more than 100 feet in length and arching approximately 50 feet across a ravine. The bridge was carved over millions of years as water dissolved the softer layers beneath the resistant Black Hand sandstone — the same Mississippian-period formation (approximately 340 million years old) that created the gorges, caves, and waterfalls throughout Hocking Hills.
The 202-acre preserve is managed by the Ohio Department of Natural Resources, Division of Natural Areas and Preserves. Unlike the main Hocking Hills State Park trails, this is a State Nature Preserve — a higher level of protection with stricter rules designed to safeguard rare plant communities, nesting birds, and fragile geological features.
Trail Details
The preserve's trail system covers 2.75 miles and is rated moderate difficulty. The terrain includes uneven footing, exposed roots, and moderate elevation changes. Sturdy hiking shoes are strongly recommended — this is not a paved or boardwalked trail. The trail is not wheelchair accessible.
Allow approximately 90 minutes to 2 hours for a comfortable hike through the full trail system. The trail winds through hemlock-shaded hollows before reaching the natural bridge overlook, then continues along the ravine rim.
Rules & Regulations
All pets are prohibited — no exceptions. This applies to dogs of all sizes, even carried or in strollers. The prohibition protects ground-nesting birds and fragile plant communities.
Open daily, year-round. No entry fee, no parking fee. All vehicles must exit the lot by dark.
Off-trail hiking is prohibited. The preserve contains rare and endangered plant species that cannot survive foot traffic.
Drone operation is prohibited under Ohio Administrative Code in all state nature preserves.
No collecting of plants, rocks, fossils, or any natural material. Pack out everything you carry in.
Climbing on or around the natural bridge and cliff faces is prohibited for both safety and conservation.

Dog-Friendly Alternatives
If you're traveling with a dog, the preserve isn't an option — but several excellent trails nearby allow leashed pets. Rock House (10 min), Old Man's Cave (15 min), Ash Cave (15 min), and Cedar Falls (15 min) all welcome dogs on a 6-foot leash. Full details at HockingHikes.com.
