Red River Gorge: Kentucky's Sandstone Wilderness
Two and a half hours south of Indianapolis in the Daniel Boone National Forest, Red River Gorge Geological Area contains the highest concentration of natural sandstone arches east of the Rocky Mountains — 100 arches in a 30,000-acre wilderness of 300-foot cliff walls, narrow slot canyons, and old-growth forest. The area is one of the most serious rock climbing destinations in the eastern United States; the Red — as climbers call it — receives 400,000 visitors annually, most of them climbers. For hikers, the 36-mile Sheltowee Trace National Recreation Trail and dozens of shorter loops access the arches and cliff-top views that define the gorge. Natural Bridge State Resort Park anchors the west end of the gorge with its own bridge (78 feet tall, 65 feet wide), accessible via a 20-minute hike.
