Via ferrata — "iron way" — routes are the Dolomites' most distinctive outdoor activity: fixed iron rungs, stemples, ladders, and cables bolted into otherwise vertical rock faces, allowing relatively non-technical climbers to reach high terrain that would normally require roped alpine climbing. A via ferrata harness and a short lanyard are all the equipment you need; a good head for heights helps considerably.
The routes range from gentle walks with a few easy iron-rung sections to serious multi-hour climbs on near-vertical walls above 2,000 metres. Beginners might start with the Ferrata Averau above Cortina, or the routes around the Cinque Torri; experienced via ferratists tackle the Ferrata Lipella on the Tofana di Rozes, or the historic Ferrata della Marmolada. The season runs from late June to late September; outside this window the routes may be iced over. Many guided half-day trips are available from the main valley towns if you'd rather have expert company for your first attempt.
