Boulder problem

A Boulder problem refers to a specific challenge or sequence within rock climbing, typically performed on a short, natural rock formation or an artificially constructed wall no higher than about 20 feet. Climbers aim to complete the problem by reaching the top using a series of precise movements, often without the use of ropes or harnesses, relying instead on thick mats (crash pads) for safety. Each problem varies in difficulty, testing strength, technique, and problem-solving skills. In essence, a Boulder problem is a well-defined, short climbing route that pushes climbers’ physical and mental abilities.
