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 ancient history of this beautiful panoramic peak.

very panoramic peak on the plain

The climb to Monte Summano is always beautiful and interesting and being exposed to the south it can be done practically all year round. From the top there are trails that vary in difficulty and beauty but are always fun and exciting.

Where do we start from? I don't know this area but I would like to go there.

The Bocca Lorenza is nothing more than a cave (which if I'm not mistaken is also used for speleology) be careful not to go too far because you risk slipping
