Mammoth Cave National Park offers an extensive network of bicycling and hiking trails that allow visitors to experience the park’s lush forests, rolling hills, and rich cave history above ground.
Mammoth Cave National Park in Kentucky is renowned for its vast cave system, the longest known in the world, but it also features over 70 miles of hiking and biking trails winding through diverse landscapes including hardwood forests, river valleys, and karst formations. Established in 1941, the park covers over 52,000 acres of protected land, where visitors can explore surface trails that offer scenic overlooks, wildlife viewing opportunities, and a connection to the historic cultural heritage of the region. The trails vary from easy walks along old railroad grades and riverbanks to more rugged paths that challenge hikers and mountain bikers. Popular trails such as the Cedar Sink Trail and the River Styx Trail provide insights into the park’s geological features and history of early settlement, while the Green River Bluffs Trail reveals dramatic views of the Green River valley. Bicyclists often use the park's Fire Trails, old service roads repurposed for mountain biking, where a moderate level of fitness and skill is recommended. The trails provide a contrast to the underground cave tours by highlighting the natural surface environment, which includes rare plants, bird species, and opportunities for solitude away from the caves' crowds. Interpretive signs along many trails enhance visitor understanding of the park’s ecosystem and human impact. For visitors who want a combination of outdoor activities, the park’s trail system complements other recreational options such as canoeing on the Green River and guided cave tours, making Mammoth Cave National Park a comprehensive outdoor destination.
