Walk-up terrain

The term "walk-up" or "trek" is used to describe terrain in which no technical equipment is needed. To traverse this terrain, mountaineers hike long distances to a base camp or the beginning of rough terrain, either following trails or using navigation techniques to travel cross-country. Hiking may be a strenuous activity, and adequate physical fitness and familiarity with the wilderness is necessary to complete a hike; it is also a prerequisite of success in all aspects of mountaineering.
