Italian and Austrian troops faced each other in the most hostile environment imaginable from May 1917 to November 1917. Stalemate ensued after both sides entrenched themselves in unassailable mountain positions. This circular ski tour takes in some of the most awesomely beautiful Dolomite peaks and massifs, including the Civetta, Monte Pelmo, the Tofane, the Lagazoi, Conturines, Settsass, Sassongher, Sella and the Marmolada. Tunnel systems, trenches and cannon and machine gun enplacements remain as reminders of these bloody events. The circular ski tour can be started at San Cassiano/St. Kassian, Corvara, Arabba and Ciapela/Marmolada. Choosing Alta Badia as the starting point, the route leads across the Campolongo Pass to Arabba, then on to Porta Vescovo and Malga Ciapela/Marmolada. At this point you can make a detour to ski on the Marmolada glacier (3,342 m). The circuit continues via the ski bus to Alleghe on the the Civetta ski region slopes, then by ski bus from Pescul to the Fedare hut. From there, continue on the Averau and ski down to Cinque Torri. The ski bus takes you back to the Lagazuoi (Alta Badia) from the Cinque Torri car park. The First World War ski circuit can be skied clockwise or anticlockwise and is 10 km in length. Half is covered on skis, the other half using lift facilities and ski buses. It also includes a horse-drawn sleigh ride.
