Abseiling also called rappelling, is the controlled descent down a rock face using a rope. Climbers use this technique when a cliff or slope is too steep and/or dangerous to descend without protection. Rope access technicians also use this as a method to access difficult to reach areas at height for various industrial applications like maintenance, construction, inspection and welding. Rescue teams are also known for using this method as a way to access injured or stranded victims.
Abseiling is used to navigate the steep descents associated with canyoning.
