Bouldering

Bouldering is a type of rock climbing. Bouldering comes without gear, belayer, and associated distractions. As such, it allows a climber to focus completely on the terrain and their movement. It is climbing heights at which the climber does not usually suffer serious injuries in case of a drop. To protect from injuries there are usually special bouldering mats underneath the climber. It is usually practiced on large natural boulders and in climbing gyms.
