Serpent Mound & the Southern Ohio Hill Country — Effigy Earthworks, Lakes & Hidden Caves
South of Columbus the land crumples into the ancient, forested hill country where the last glaciers stopped, leaving a landscape of deep gorges, dolomite caves, and one of the great mysteries of the prehistoric world. This unhurried three-day escape centers on the Great Serpent Mound near Bainbridge — the largest surviving effigy mound on earth, a quarter-mile serpent of earth uncoiling along a ridge. Day one explores the mound and the quiet village of Bainbridge; day two roams the lakes, waterfalls, and prairie of Paint Creek and Rocky Fork State Parks and the cliff-top earthworks of Fort Hill; day three wanders Pike Lake State Park and the hidden caves and gorges of the Highlands Nature Sanctuary — the storied "Seven Caves" — before the drive home. It is a serene, deeply scenic weekend in Ohio's oldest country. Note: at the Highlands Nature Sanctuary the gorge-rim trails are the draw — the historic 'Seven Caves' are no longer open for public cave tours, so come for the trails and overlooks rather than caving.
