Via ferrates were born and developed in Dolomites, and you can see the best and the oldest examples right there. It’s origins are primarily associated with the Great War, which aided the movement of troops in the otherwise difficult Alpine terrain.
These relics of the WW1 are still present and used as means of enjoying panoramic views and accessing difficult peaks. Due to its permanent set up in rocks, via ferratas are appealing to both inexperienced climbers as well as experienced mountaineers. Your only requirements are a good head for heights and some basic equipment which can take you long way up.
