With increased accessibility to climbing walls, and gyms, more climbers now enter the sport through indoor climbing than outdoor climbing. The transition from indoor climbing to outdoor sport climbing is not very difficult because the techniques and equipment used for indoor climbing are nearly sufficient for outdoor sport climbing. Nevertheless, climbing on natural rock often poses a greater challenge as bolts may be placed at greater distances and other risk factors such as rockfall, the possibility of falling onto ledges and other rock features, as well as the quality of bolts and anchors must be taken into consideration.
