Collie Ridge Trail

Collie Ridge Trail is one of Mammoth Cave's quieter backcountry routes, and that's exactly the point. This nearly four-mile out-and-back follows the spine of Collie Ridge through mixed hardwood forest — mostly oak, hickory, and tulip poplar — with the canopy filtering light into something almost cathedral-like during peak leaf season. The trail surface is packed dirt with scattered roots and the occasional limestone outcrop, nothing technical but enough to keep you paying attention. You won't find cave entrances or dramatic overlooks here; what you will find is the kind of deep-woods Kentucky silence that the main cave tour crowds never experience. The ridge undulates gently, with a few short climbs that qualify as moderate but never punishing. This is a trail for hikers who came to Mammoth Cave and realized the best thing about the park might actually be above ground.
