Hiking the Parks & Preserves of Ohio. Clifton Gorge State Nature Preserve. Years ago I went canoeing on the Little Miami River; the river serenely wound its way between the wooded river banks. But at Clifton Gorge, the Little Miami River is something altogether different; it plunges over falls and rapids between narrow cliffs of dolomite and shale. The river and surrounding cliffs are the main attractions of Clifton Gorge State Nature Preserve, a 268 acre preserve located adjacent to John Bryan State Park. The Little Miami River flows through both, with the nature preserve upstream where the river roils.
