Lagazuoi Piccolo, Mountain summit in Province of Belluno, Italy.

Lagazuoi Piccolo is the lower of the two Lagazuoi summits, rising to 2,778 metres in the Fanes group of the Dolomites, a few hundred metres south of the South Tyrol border. It is separated from the 2,835-metre Großer Lagazuoi by the Forcella Lagazuoi saddle at 2,572 metres. Its south side drops steeply, while the north side is flat and plateau-like.

Italian and Austro-Hungarian troops built a network of military tunnels inside this mountain during World War I. These passages were part of the intense fighting that took place in this high mountain zone.

The Kaiserjägersteig follows the route by which Austro-Hungarian Kaiserjäger supplied their positions for two and a half years; along it a kitchen and a dormitory have been rebuilt and furnished with original objects. A rebuilt suspension bridge stands where the old one crossed, and short side paths show how the soldiers lived.

The mountain is accessible via the Falzarego Pass, and during warmer months a cable car provides direct access to the summit. Visitors should be prepared for changing weather conditions and bring appropriate gear.

The restored military tunnels allow modern visitors to walk through the same passages where soldiers positioned themselves during mountain warfare. Entering these underground spaces gives a direct sense of how troops lived and fought on this high peak.
