A simply wonderful place, easy to reach from the Carpanè-Valstagna station, following a well-marked path along the Brenta River. The staff was equally fantastic, allowing us to follow the cave tour in both Italian and English (part of my group didn't speak Italian). I recommend going in spring; it's cooler and there's usually less traffic, so you can enjoy it all better. ;)

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 Trenchers of Monte Campolongo - not to be confused with the mountain of the same name and its fort exactly on the opposite western side of the Asiago Plateau - are a long and deep Italian trench from the First World War, dug on a promontory which dominates the final stretch of the Val Brenta. It had no active role during the Great War, but served as an extreme bulwark to prevent a possible invasion of the Austro-Hungarian army from Valsugana. Cleaned and recovered, it features walkways, outposts, tunnels and shelters in a dense and silent forest: today the vegetation largely covers the view, especially in summer, but at the time the view of the valley was clean. You can follow the winding of the trench from inside or from above, along a path complete with little bridges... or a little and a little!

The Oliero caves are a complex of caverns located on the slopes of the Sette Comuni plateau, near the hamlet of Oliero (municipality of Valbrenta). Much of the water that penetrates through the plateau above flows from the caves, a classic example of karst phenomena. There are four caves currently open to the public: Covol dei Veci and Covol dei Siori from which the Oliero river flows; while the two upper ones, Covol dei Assassini and Covol dee Soree, are now dry. To visit the caves it is necessary to have a ticket and entry is allowed only with a guide. In the park of the caves it is also possible to visit the museum of speleology and karst phenomena and relax at the bike grill bar.
