Topo image of the cliff Toix Est in Costa Blanca in Spain, by climber Chris Craggs from a Rockfax guidebook. Before discussing individual routes, a climbing guidebook will outline the history and current status of climbing ethics applicable for the location including for example whether the use of bolts for sport climbing is allowed, and other local customs (e.g. use if non-clean aid climbing ...
These two rock climbing sub-disciplines can be conducted in one of several ways: [3] [4] Aid climbing is a form of rock climbing that uses artificial aids such as aiders, pitons, and other mechanical devices to assist in ascending a route. Much of rock climbing began as aid climbing, and even by the 1970s, many big wall routes required aid (e.g.
