Simply, climbing is an ascent completed for the athletic and mental challenge.The skills and specialized equipment required for technical climbing are what differentiate it from hiking or mountain climbing. Most climbers start out on rock scrambles or at indoor climbing gyms. As they gain experience, they find they've entered a sport with many facets and a 150-
year-plus history. For some people, climbing becomes a lifelong pursuit; climbers as young as 7 and as old as 70 participate at a very high level. For most climbers, the sport means trying to solve a problem-ascending a rock face, a frozen waterfall, a high mountain-using the minimum amount of equipment. A climber could use a ladder to scale a cliff, or easier yet, simply walk around the back side to the top but the pursuit of difficulty for difficulty's sake is the challenge that unites climbers of all types.
