Countless trees fly by under your feet as you soar hundreds of feet above the ground. Suddenly, the forest floor below opens up into a gorge. At Red River Gorge Zipline, riders witness this incredible sight on regular canopy tours set amid the picturesque wilderness of Daniel Boone National Forest. The system's ziplines span more than 4,000 feet above the forest canopy, with the longest reaching about 1,900 feet in length. At the end of the tour, dual racing ziplines send riders charging down from more than 200 feet above the ground, and reaching speeds exceeding 50 mph. All of Red River Gorge Zipline's guests are strapped into harnesses for the duration of their tours, while helmet cams document their adventure.
