Spectacular tunnel from the First World War: endless, steep, humid, and completely dark. A flashlight is essential. Currently (2025), the summit is closed due to a collapse: from below, it is accessed via the Franco Galli Equipped Path; from above, by circumnavigating the Corno bastion and climbing a challenging vertical metal ladder about fifteen meters high. EE. Corno Battisti is a rocky outcrop dominating the Vallarsa Valley. Due to its strategic position, it was fiercely contested during the First World War. At the beginning of the conflict, it was in Italian hands, but with the Strafexpedition of 1916, the Austro-Hungarians occupied it; the Italian army, unable to retake it, dug a mine tunnel from below to pierce the Corno and blow up the summit; the Imperials, in turn, dug a countermine tunnel from above. Everything was ready for the detonation, but a coup by a few brave men allowed the Italians to conquer the summit, which they held until the end of the war!

Corno Battisti, an isolated rocky bastion of the Pasubio Group, overlooking the Vallarsa Valley, offers a spectacular view of the long valley and the surrounding mountains: Pasubio, Sengio Alto, Carega, and Monte Zugna. Precisely because of its strategic position, it was fiercely contested during the First World War: the ability to monitor all troop and supply movements along the valley floor from up there made Corno a crucial point to be occupied and defended at all costs... it was in fact nicknamed "the eye of Pasubio" or "the spy of Vallarsa." At the beginning of the conflict, it was a garrison of the Italian army, but with the Strafexpedition of 1916, it was occupied by the Austro-Hungarians. Unable to recapture it, the Italians dug a mine tunnel from below to pierce the Corno and blow up the summit; the Imperials, in turn, dug a countermine tunnel from above. Everything was ready for the detonation, but a coup by a few brave men allowed the peak to be retaken by the Royal Army, which held it until the end of the war. The Austro-Hungarian observatory still survives at the summit. The bowels of the promontory are instead carved out by a surprising and easily navigable labyrinth of dark, damp tunnels with steep steps (EE). In 1916, near the summit, the Austro-Hungarians captured the irredentists Cesare Battisti and Fabio Filzi. They were immediately taken to Trento and hanged at Buonconsiglio Castle as traitors. For this reason, the peak, known at the time as 'Corno della Vallarsa', was renamed 'Corno Battisti' after the war. https://it.wikipedia.org/wiki/Monte_Corno_Battisti https://www.esercito.difesa.it/storia/pagine/monte-corno.aspx

This is a natural arched window, which allows passage and a view from the west side to the east side and vice versa, of Mount Priaforà. Located just below the summit of the mountain itself. A strategic place during the Great War, it was conquered by the Italian army with enormous sacrifices and costs. Below the summit of the mountain there are imposing military tunnels with windows overlooking the Astico valley and towards the Posina valley. The summit cross is noteworthy

The Campiglia gunboat, built in 1917, is an interesting example of a fortification dating back to the First World War. Located in a cave along the Scarubbi road, which leads to Malga Campiglia, this military structure was part of the Italian Alpine defenses during the conflict. The site, hidden in the rock, offers a panoramic view of the surrounding valleys and represents an important historical testimony of those years. The strategic position of the gunboat, protected by the natural cavity of the mountain, allowed it to effectively control the area and respond to any enemy attacks.

'Tunnel dei Fucilieri' in the signage: Austro-Hungarian defensive tunnel from the Great War, which passes through the grassy hill of Smelzar, at the foot of Forte Dosso delle Somme, with posts at regular intervals aimed at the underlying Val Terragnolo. Upon exiting, you suddenly emerge onto an exposed but extraordinary panoramic balcony between Val Terragnolo and the Altopiano di Lavarone, before arriving with a steep climb to the fortress.

From the Venetian dialect 'pria forà', perforated stone: a suggestive natural arch that opens a spectacular window onto the Val d'Astico and the Asiago plateau. With a width of about 3 meters and a height of about 5 meters, it is visible from kilometers away from the valley below and from the opposite plateau.

The best times to visit are generally during the spring, summer, and early autumn months (April to October) when the weather is milder and more predictable, making outdoor exploration and access to sites like the Hermitage of San Colombano and Forte Pozzacchio more comfortable. Some historical tunnels, like those at Corno Battisti, can be damp and dark, so a flashlight is essential regardless of the season.
Many of the historical sites, such as Forte Pozzacchio, can be engaging for families interested in history, offering an immersive experience into World War I engineering. The Hermitage of San Colombano, with its 102 steps, might be challenging for very young children but rewarding for older kids. Always check specific accessibility for each site, as some involve stairs or uneven terrain.
While many outdoor trails in the region are dog-friendly, specific rules apply to historical sites and structures. For example, dogs are generally allowed in the outdoor areas around Forte Pozzacchio, but often not inside the excavated fort itself. It's advisable to check specific regulations for each site, such as the Hermitage of San Colombano, before visiting with your pet.
