A ropes course is a challenging outdoor personal development and team building activity which usually consists of high elements, low elements, or some combination of the two. Low elements take place on the ground or above the ground. High elements are usually constructed in trees or made of utility poles and require a belay for safety.

In climbing and mountaineering, the term belaying refers to techniques used to create friction within a climbing protection system, particularly on a climbing rope, so that a falling climber does not fall very far. A climbing partner typically applies tension at the other end of the rope whenever the climber is not moving, and removes the tension from the rope whenever the climber needs more rope to continue climbing. The belay is the place where the belayer is anchored, which is typically on the ground, or on ledge but may also be a hanging belay where the belayer themself is suspended from an anchor in the rock on a multi-pitch climb.
