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/

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.

An extremely evocative and interesting site, hidden and unexpected, almost surreal: it surprises with its vastness and the slender square columns supporting the titanic ceiling... it feels like being inside a temple in ancient Mesopotamia or in the mines of Moria from Tolkien's memory! The Priàre (from 'pria', meaning stone in the Venetian dialect) are a complex of underground quarries and tunnels for the extraction of the renowned "soft Vicenza stone," active from Roman times until the mid-20th century. During the bombings of World War II, the quarries were used by the inhabitants of Montecchio as a refuge; between 1972 and 1985, they were exploited as a mushroom farm, thanks to the humidity and constant temperature throughout the year; Afterwards, they were abandoned until their redevelopment and safety measures in 2000. Vicenza Stone is a highly prized material, always highly appreciated and sought after in architecture and construction: beyond its aesthetic appeal, it is soft and malleable when freshly quarried, but upon contact with air, it "seasons," hardening and becoming extremely resistant over time. This rock was used to build the Montecchio fortresses and by Andrea Palladio for his works. It has always been quarried strictly by hand, using the same technique for millennia, in square blocks; this is why the quarries have such a geometric appearance. Open Sunday afternoon; entry is only possible with a (very interesting) guided tour lasting about 40 minutes; admission is €3. Please note that payment by POS is not possible due to the lack of signal. https://www.prolocoaltemontecchio.it/cosa-vedere/le-priare/

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.

The underground sites around Castelgomberto are primarily historical quarries, known locally as "priare," where the famous Pietra di Vicenza was extracted for centuries. These excavations showcase traditional stone extraction methods, some dating back to Roman times, and were crucial for constructing many important buildings in the Veneto region, including works by Andrea Palladio. Sites like Le Priare di Montecchio Underground Complex offer a direct look into this rich history.
While many sites are man-made quarries, the region also features natural karst formations. The Pietra di Vicenza itself is a soft limestone rich in fossils and marine sediments, formed from an ancient coral reef. Natural karst cavities like Lucio's Hole demonstrate the area's geological activity, with fresh air currents creating a unique 'dragon's breath' phenomenon. The Buso della Rana Cave is a prime example of an intricate natural karst system with tunnels, chambers, and underground streams.
For families, exploring the historical quarries like Le Priare di Montecchio Underground Complex can be an educational and atmospheric experience, though guided tours are often required. The Strada delle Lore is a well-beaten military road with shelters in caves, offering an easier walk through nature and history that can be suitable for families.
Inside the caves and underground complexes, temperatures remain constant, typically between 10 and 12°C year-round, even in summer. It's advisable to wear layers, including a jacket or sweater, and sturdy, comfortable shoes with good grip, as surfaces can be uneven or damp. For natural caves like Buso della Rana Cave or Buso del Sojo, a headlamp or flashlight is essential, and for more adventurous explorations, proper caving gear might be necessary.
The underground sites maintain a consistent temperature year-round, making them suitable for visits in any season. For exploring the surrounding trails and enjoying the natural landscape, spring and autumn generally offer the most pleasant weather for hiking around Castelgomberto, with milder temperatures and beautiful scenery. Summer can also be good, especially for the cooler underground environments, but be mindful of potentially hotter temperatures on outdoor trails.
Yes, guided tours are often available and recommended for many of the underground sites. For instance, Le Priare di Montecchio Underground Complex is typically accessible only with a guided tour. For natural karst systems like Buso della Rana Cave, while the entrance is freely accessible, exploring beyond the initial section requires specialized knowledge or an adventurous guided tour organized by speleological associations due to the complex and potentially treacherous conditions.
The duration of your visit depends on the specific site. A guided tour of Le Priare di Montecchio Underground Complex, for example, lasts about 40 minutes. For natural caves like Buso del Sojo, you can spend anywhere from 30 minutes to an hour exploring the main passage. If you combine a cave visit with a hike on nearby trails like the Strada delle Lore, your total exploration time could extend to several hours.
The area around Castelgomberto offers various outdoor activities. You can find numerous hiking trails, such as those detailed in the Hiking around Castelgomberto guide, with routes like the moderate 'Ponte de Fero (Iron Bridge) – Chiesetta Regina Pacis loop'. There are also options for cycling, including gravel roads and scenic loops, as highlighted in the Cycling around Castelgomberto guide, and challenging MTB trails for mountain biking enthusiasts, found in the MTB Trails around Castelgomberto guide.
Castelgomberto and its surrounding villages offer various local cafes and restaurants where you can enjoy traditional Italian fare and refreshments. While specific cafes might not be directly adjacent to every cave entrance, you'll find options within a short drive or walk in the nearby towns, perfect for a break before or after your underground exploration.
Parking availability varies by site. For popular locations like Le Priare di Montecchio Underground Complex, there is usually designated parking nearby. For more remote natural caves or trailheads, parking might be less formal, often along roadsides or in small village squares. It's always advisable to check specific access information for each site you plan to visit.
Some sites, like the initial section of Buso della Rana Cave or the main passage of Buso del Sojo, can be accessed independently, though caution and appropriate gear (like a headlamp) are essential. However, for deeper or more complex sections of natural caves, or for historical quarries that are managed sites, guided tours or special permits from local associations may be required for safety and preservation reasons. Always verify access requirements before your visit.
