The Open Air Museum of Mt. Lagazuoi

Mount Lagazuoi is a veritable "castle of rock", with spires and turrets, and with military bases hidden in its bowels. During the Great War the Italian and Austro – Hungarian armies dug shelters in its interior for men and arms, transforming it into an impenetrable 20th century fortress.

Today you can visit the restored tunnels, trenches and machine gun posts in the Open Air Museum of Lagazuoi. The numerous routes will take you on a behind-the-scene tour of a dramatic war fought at a high altitude and which was unique in the history of man.

The War on Mt. Lagazuoi

The entire area of the museum is crossed by paths viable on foot. Almost all the tunnels and trenches have been cleared and restored thanks to the work of numerous volunteers. Restoration of the steps has granted easier access to the sloping stretches of the tunnels.

There are visits to several different routes, some longer and more difficult, others shorter and easier.

There are four ways to reach the summit of Mount Lagazuoi,
the heart of the Open-Air Museum:

  • on the Path of the Front-line, a wide and well marked hiking trail that runs along the front line of Mount Lagazuoi during World War I. This easy hike is suitable for everyone


  • through the Anticima-Tunnel, which was excavated by Italian soldiers on the Martini Ledge to the “Anticima” emplacement of Lagazuoi as a mine tunnel and exploded on 20 June 1917. This tunnel is the most daring tunnel system that has been realized during the First World War. It is almost one kilometre long and has been completely restored

  • on the Kaiserjäger path, a rather challenging hiking trail with some exposure but with well placed wire ropes. The Kaiserjäger path was the communication way between the bottom of the valley and the high emplacements on Mount Lagazuoi, and was used to supply food, munitions, and war equipment. The path has now been repaired and can be travelled for its entire length.
