What is rappellen?

Rappelling (also known as abseiling) is a technique used in climbing, mountaineering, and other outdoor activities that involves descending from a vertical or near-vertical surface using a rope and specialized equipment. It is a controlled descent technique that requires skill, training, and experience. The technique is also used in rescue operations, where it allows rescuers to descend to an injured or stranded person on a cliff or building. Rappelling can be a thrilling and exciting adventure activity, but it should always be done with safety in mind, using proper gear and following established protocols.
