John Bryan & Clifton Gorge — The Little Miami's Dolomite Canyon
An hour northeast of Cincinnati, the young Little Miami River has sawed a startling gorge through the limestone and dolomite of the Springfield plateau, and the walk along its rim and floor is the finest short hike in southwest Ohio. John Bryan State Park protects the wide lower gorge, where the Rim Trail and the Gorge Trail thread past mossy cliffs, hemlock stands, and rapids; upstream, the Clifton Gorge State Nature Preserve narrows to a slot where the river roars through a channel barely twenty feet wide beneath 100-foot walls. The day ends at Clifton Mill — one of the largest working water-powered gristmills in the country, turning since 1802 — and in the artist village of Yellow Springs, whose cafes and Glen Helen trails give an easy, unhurried counterpoint to the gorge. A single day, but a genuinely wild and geologically dramatic one.
