Red River Gorge Zipline Tours propels sightseers through the canopy of Daniel Boone National Forest along a suspended trail that includes bridges and five ziplines that connect platforms in the trees. Nature tourists spend two to three hours carefully hiking alongside ACCT-trained guides who make sure each participant is able to coast along ziplines that, like scrolls of unedited epic poems, range from 330 to 1,900 feet long. Strapped into a sturdy harness, gliders cop scenic views of foliage and cliffs in the Natural Bridge State Park and Red River Gorge as they soar at speeds of up to 50 miles per hour and as high as 250 feet above the gorge. Guests can commemorate their adventure with an individual picture as they careen through the trees or a group photo with the flock of peregrine falcons that adopted you as one of their own after seeing you fly.
