Overview

About This Trail

This 9-mile route follows the 1886 Mammoth Cave Railroad bed, now a maintained gravel hike-and-bike trail. You'll face sustained steep grades and potholes that demand focus—this isn't a casual stroll. Scenic overlooks and historic interpretive sites punctuate the route, but endurance and water discipline are non-negotiable. The real trial: descent on tired legs through unshaded gravel.
