Top 6 Caves around Villaverla

The Buso della Rana is the largest cave in the Veneto region and one of the most extensive in Italy, with a network of caves stretching almost 30 km in total (40 km including the Pissatèla complex above, to which it is connected). Located beneath the Faedo-Casaròn Plateau, it is an intricate karst system that collects and channels the plateau's waters into the Rio Rana, which flows at the entrance. It was formed when rainwater seeps into the permeable limestone surface layer and, encountering the underlying impermeable basalt (volcanic rock), flows laterally, eroding the rock. Over millions of years, this has created a complex labyrinth of horizontal tunnels, chambers, chimneys, siphons, and small lakes traversed by underground streams. Because it drains the plateau's waters, the cave is subject to flash floods, making exploration treacherous. Inside, the temperature remains constant between 10 and 12°C year-round. It is freely accessible through the monumental entrance and by proceeding along the Main Branch for about fifty meters, until reaching the first flooded corridor or Siphon, a horizontal constriction that requires crawling. From there, it is the preserve of speleologists or exciting and adventurous guided tours organized by associations like Biosphera (see link). The internal branches are not marked, and one must know the way. The name of the cave has nothing to do with the amphibian, but is an Italianized term from the Cimbrian word "roan," meaning "rocky wall," referring to the cliff at the entrance. https://www.busodellarana.it https://esplora.biosphaera.it/luoghi/buso-della-rana/

Road that leads from Faedo to Monte di Malo

Descent from Faedo towards Monte di Malo

The Buso del Sojo (in Venetian dialect) or Buco del Soglio (in Italian) is a spectacular cave that extends into the bowels of the mountain of the same name, piercing it from side to side, with a main branch that is almost straight and horizontal. You descend into the tunnel via a metal ladder and some steps carved into the rock: the tunnel extends for almost 500 meters, in total darkness, wide enough to be walked through standing up, until the opening on the steep opposite side of the large rocky spur. About halfway along the route, a pair of lateral branches intersect with opposite directions: one leads to a slit that looks towards Monte di Malo, the other continues towards the inside of Monte Soglio, becoming increasingly narrower. To exit, you have to retrace your steps. According to speleologists, this cave is probably connected to the famous and underlying Buso della Rana, but the passages are blocked by landslides: after all, the entire area above Monte di Malo is a Gruyere of karst cavities. During the First World War, after the Strafexpedition of 1916, the cavity was used and profoundly modified by the Italians for military needs, like many natural inlets present on the Faedo-Casaron plateau: it was part of the defensive complex of the Ortogonale 1, the long fortified line that started from Campogrosso and reached Vicenza, along the ridge watershed between the Agno and Leogra Valleys, to defend the Po Valley. The main gallery was enlarged, as evidenced by the holes of the pneumatic hammers, and several slits were opened as observation posts and positions for light weapons, to control the possible enemy advance in the lower Val Leogra. The Buso del Sojo is truly impressive and anxiety-inducing, but electrifying and fascinating! Despite the easy access and easy walkability, it is still a cave, that is, an environment to be approached with due caution and awareness. Not recommended for those who are afraid of the dark, narrow spaces and creatures of the darkness: on the walls, in the first few meters you will encounter spiders and crickets, annoyed and agitated by the light, while proceeding you will find numerous bats hanging from the ceiling.

To admire this curious phenomenon, a detour from the main road is necessary. Once you reach the place, just look out into the well (with a diameter of about 50 cm) from which what is sometimes called "dragon's breath" seems to emerge from. It is nothing more than a karst cavity (characteristic of the Faedo-Casaron plateau) from which fresh air comes out (which varies between 7 and 13 degrees). Especially in the summer period, the typical rustle of the exchange of hot and cold air masses at the mouth of the cave is clearly audible. The cavity, commonly called "Buso del Lucio", was discovered by the Maladense speleologist Lucio Zanini. The valley that you travel along following the Campipiani-Faedo path is called “Valle dei Vischi”. The origin of this name is not known but it probably refers to the sound effects (breathing, hissing, moaning) that the blowing caves produce in particular climatic conditions.
