Routes: Routes are typically long and sustained in grade. Experience climbing and using technical rock climbing equipment is required to safely climb at Devils Tower National Monument. Consult multiple sources for informaiton on a route, as suggested gear varies between guidebooks. Rappelling: The majority of climbing accidents and deaths on the Tower occurred during the rappel. The National Park Service does not maintain anchors - inspect all anchors and back them up if necessary. Ensure you know the location of your rappel route before you begin. Start rappels over the nose of columns to prevent ropes from jamming in cracks. Avoid knocking loose rock onto climbers below. Many rappels require two ropes; know the distance of your planned rappel before beginning.
