A view from Chimney Top Overlook above the Red River Gorge in eastern Kentucky. The Red River Gorge is a scenic and relatively remote canyon covering roughly 29,000 acres located in the Daniel Boone National Forest. It is known for its sandstone cliffs, waterfalls and natural bridges. With its more than 100 natural bridges and arches, it is largely responsible for Kentucky having one of the highest concentrations of natural bridges and sandstone arches in the United States, and is second only to Utah in that regard.
