Top 10 Caves ボルゴ・バルスガナでの

Very steep section that leads to the top of Ortigara, it is useful to have a headlamp with you

The tunnel was initially an Austro-Hungarian machine gun emplacement (2093 m), designed to defend the overlooking 2101 m of Mount Ortigara. It was later captured by the Alpine troops during the first attack on June 10, 1917, becoming the headquarters of the Italian command of Colonel Pietro Biancardi, from whom it takes its current name. A must-see on the trail connecting the summit of Mount Ortigara to the Agnella Pass: fascinating, steep, and facilitated by steps and ropes. The imperial emplacements are accessed by descending into a shaft using metal supports (technical descent, only for experts).

During the First World War, in view of the Battle of Ortigara in 1917, the area on the eastern slopes of Cima Caldiera was transformed into an Italian logistics base of enormous tactical importance: one of the main storage centers for food, ammunition, tools and materials needed for combat and the sustenance of the troops. It was located on the slope sheltered from enemy fire, but close to the front line, to which it was connected by a web of walkways; it was accessible via a wide and comfortable road from Piazzale Lozze, which is now used as a path; the six tunnels dug one after the other, connected internally by a single corridor, served as warehouses and were hidden from view by external wooden barracks that, leaning against the rock, covered the entrances. Two interesting tables show the inventory of the goods stored: food for the soldiers, daily rations and materials for the Engineers.

the sinkhole is quite impressive and quite intimidating

Trenches along the path that leads to Cima Caldiera. They are part of the Eco Museum of the Great War. The trenches and the excavated cavities served as warehouses for supplies for the troops of Ortigara.

The diameter and depth of the chasm are impressive. It's scary. I advise caution in the cold months (and not only) as there is ice everywhere and the area becomes a skating rink, although there are protective barriers. I speak from lived experience....

Karst gorge typical of this type of mountain. There are many throughout the plateau, just look carefully at the maps

Unpaved stretch, not too demanding, from where you can enjoy very beautiful landscapes and on occasion not very frequented passages
