Upper Falls greets walkers the moment they descend from the trailhead kiosk: Old Man's Creek pours roughly twenty feet beneath a graceful 1930s stone arch bridge into the first emerald pool of the gorge. This is the gateway to what is often called the most visited half-mile in Ohio's state park system — a sandstone slot canyon of cliffs, pools, and hand-laid Depression-era stonework that begins right here. The stop orients visitors to the full gorge loop ahead, from the swirling Devil's Bathtub down to Old Man's Cave and Lower Falls, and points out how natural erosion and Civilian Conservation Corps craftsmanship together built the scene overhead and underfoot. Spray keeps the steps glistening year-round, so footing and the best railside photo angles are covered before the walk heads downstream.
Down the stone steps from the kiosk, the gorge takes you in one swallow. That white ribbon ahead is Upper Falls — Old Man's Creek dropping about twenty feet beneath the stone arch bridge, straight into the first green pool of the canyon. You're standing at the front door of the busiest, best-loved half mile in these hills, and the next hour will show you why.
Everything around you was built twice. Nature went first: the creek spent unthinkable stretches of time cutting down through layered sandstone — a tough roof, a soft middle, a tough floor — and carved itself this slot of cliffs and pools. Then in the nineteen thirties a crew of young men went to work on what nature left behind, and that arched bridge over the falls, the steps under your boots, the walls that hold the trail to the cliff — all of it is their stonework, still carrying every visitor who comes, some ninety years on. Hold that thought. Their whole story waits at a little cabin downstream, and it ranks among the finest stories these hills keep.
Here's the shape of the walk: follow the creek downstream along the gorge floor — past a stone bathtub the Devil supposedly soaks in, under a bridge that crosses the whole canyon in one stride, to the great cave that gave an old man a home and this park a name. Then you climb out at the far falls and ride the rim home. Call it a mile, most of it steps and stone — a real but moderate climb, down into the gorge and back out, with a stair or two under a waterfall. Worth every step if your group's up for it.
But let me be straight, because this is family country. This is an optional hike, not a requirement. The stairs are steep in places, the rock stays slick, and there are open cliff edges with the rail the only thing between you and the drop — so if you bring the little ones, keep them close and well back from those edges the whole way. And if stairs aren't in the cards today, you lose nothing: stand right up top at Upper Falls and the arch bridge for the best falls view in the gorge from the level path, and save the deep canyon for another trip.
Two last notes before you move. Spray keeps this rock slick all year, even when the sky's been dry — so take the steps slowly, hands free. And photos happen from behind the rails. Now — downstream.
