Mammoth Cave & Cave City's Quirky Route 66 Cousin
This two-day Kentucky road trip pairs the world's longest cave system with one of the most cheerfully eccentric small-town strips in the South. Day one descends into the grand caverns of Mammoth Cave for the Historic Tour and the dreamlike Frozen Niagara formations, then walks the Green River bluff above the cave entrance. Day two explores Cave City, Kentucky — a Route 66-adjacent strip of roadside Americana including the beloved Wigwam Village Inn (where 15 cement teepee rooms have housed travelers since 1937), an outdoor sculpture garden of life-size dinosaurs, and a short underground boat tour through the Lost River Cave to a hidden lake beneath the earth.
