A via ferrata (Italian for "iron path", plural vie ferrate or in English via ferratas) is a protected climbing route found in the Alps and certain other Alpine locations. The protection includes steel fixtures such as cables and railings to arrest the effect of any fall, which the climber can either hold onto or clip into using climbing protection. Some via ferrata can also include steel fixtures that provide aid in overcoming the obstacles encountered, including steel ladders and steel steps. The term "via ferrata" is used in most countries and languages except notably in German-speaking regions, which use Klettersteig—"climbing path" (plural Klettersteige). A via ferrata is a climbing route in the mountains that employs steel cables, rungs, or ladders, fixed to the rock to which the climbers affix a harness with two leashes, which allows the climbers to secure themselves to the metal fixture and limit any fall. The cable and other fixtures, such as iron rungs (stemples), pegs, carved steps, and ladders and bridges, provide both footings and handholds, as well. This allows climbing on otherwise dangerous routes without the risks of unprotected scrambling and climbing or the need for technical climbing equipment. They expand the opportunities for accessing difficult peaks as an alternative to rock climbing and mountaineering, both of which require higher skills and more specialized equipment. Via ferratas can vary in length from short routes taking less than an hour to long, demanding alpine routes covering significant distance and elevation ( or more of ascent) and taking eight or more hours to complete. In certain areas, such as the Brenta Dolomites, it is possible to link via ferratas together, staying overnight in mountain refuges, and so undertake extensive multi-day climbing tours at high elevations. In difficulty, via ferratas can range from routes that are little more than paths, albeit in dramatic and exposed situations, to very steep and strenuous routes, overhanging in parts, demanding the strength—if not the technique—of serious rock climbing.
