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

The Laghi region offers a diverse range of subterranean experiences. You can explore natural karst formations with stalactites and stalagmites, such as the Remeron Cave near Varese or the Caves of the Dream of San Pellegrino Terme. Additionally, the area is rich in historical military tunnels and fortifications from World War I, including sites like the Gun Emplacement Tunnel of Monte Cengio and the WW1 Command Gallery.
Yes, several caves are suitable for families. The Remeron Cave near Varese offers guided tours and an educational path for younger visitors. The Caves of the Dream of San Pellegrino Terme are also easily accessible, even for children, featuring illuminated galleries and aerial trails to observe unique karst sculptures.
Many caves in the Laghi region played a crucial role during World War I. Sites like the Corno Battisti, known as 'the eye of Pasubio,' were fiercely contested due to their strategic position. The Neutral Elevation Tunnel (Cimone) served as an Italian frontline stronghold, featuring an impressive spiraling tunnel. Other caves, like Cùel Zanzanù, have historical connections to 17th-century bandits.
The Laghi region, particularly the Valle dei Laghi, is characterized by significant fractured and dissolvable limestone, leading to numerous karst areas. In caves like Remeron Cave and the Caves of the Dream of San Pellegrino Terme, you can admire natural concretions, including stalactites, stalagmites, and various other karst sculptures formed over millennia.
Yes, guided tours are available for some caves. For instance, the Remeron Cave in Comerio offers guided tours that allow visitors to explore up to 50 meters deep, witnessing its natural formations. The Europa Cave in Valle Imagna is also mentioned as a precious underground treasure, often explored with guidance.
Given that many tunnels and natural caves can be dark and damp, especially historical sites like Corno Battisti or the Neutral Elevation Tunnel (Cimone), a flashlight or headlamp is essential. Comfortable, sturdy footwear with good grip is recommended, and layers of clothing are advisable to adapt to cooler underground temperatures.
The area around Laghi offers numerous outdoor activities. You can find challenging running trails, including the 'Road of 52 Tunnels' loop. For cycling enthusiasts, there are gravel biking routes like the 'Generale D'Havet Tunnel' loop. Additionally, the region is popular for mountain hikes, with routes such as the 'Achille Papa Hut' loop.
Beyond the more prominent sites, the Laghi region holds several intriguing, perhaps lesser-known, caves. The Bus of Tacoi in Val Seriana and the Bear's Cave near Como are significant underground destinations in Lombardy that offer unique exploration opportunities for those looking to venture beyond the main attractions.
The caves in the Laghi region are primarily a result of the area's geological makeup, characterized by fractured and dissolvable limestone. This landscape was significantly shaped by glaciations that occurred between 80,000 and 12,000 years ago, which carved deep incisions and created features like glacial wells, gorges, and the conditions for karst cave formation. Some, like the Caves of the Dream of San Pellegrino Terme, are of tectonic origin, formed millions of years ago.
Visitors often highlight the unique blend of natural beauty and historical significance. The 'great thrill of discovering an unknown and wonderful world' below the surface, coupled with the tangible history of WWI fortifications and command posts, makes for a compelling experience. The impressive scale of tunnels, like the WWI Fort, and the natural formations are frequently praised.
