One of the most basic and popular forms of climbing, free climbing involves scaling cliffs only using your body. Ropes and other equipment are used, but only for protection against falls. Free climbing is usually attempted in pairs, with the first climber acting as the •leaderê, moving quickly up the cliff face attaching themselves to standard protection such as cams and stoppers. The second climber acts as a •belayerê, feeding rope up to the first climber to ensure that they do not fall too far if they slip off the rocks. Free climbing is very popular thanks to the speed of ascent and •naturalê method of climbing. .
