The original series of 'iron ways' through the mountains were originally used by locals to cross from valley to valley but the routes were significantly expanded during the Tyrolean campaign in World War One, one of the most vicious arenas in the entire war that saw the Italians and Austrians slugging it out in often appalling conditions. The routes were used to move supplies, ammunition and men around, and the war years also saw the creation of opposing trenches, many of which are still clearly visible today, often astonishingly close together.
The historical element of any exploration of the Via Ferrata is fascinating enough, but the real stars of the show are the breathtaking views around almost every corner.
Days trips are possible, but it's well worth considering longer itineraries with overnight stays in charming rifugios. These remote mountain lodges are a far cry from those in France and Switzerland, and rather than dormitories full of snoring Germans, you can expect private rooms and delicious Tyrolean food and wine that will feel particularly well earned after a day traversing the stunning Dolomites.
