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 delle Anguane is a fascinating cave in the rock with a natural balcony overlooking the Chiampo Valley: a place of mystery and legends, in ancient folk tales it was the home of the anguane, evil creatures that attracted men with their comely appearance. https://it.wikipedia.org/wiki/Anguana The path to reach the cave is quite impervious and challenging, not very visible and not signposted along the asphalt road.

The Cascata dei Papalini suddenly appears in a small clearing in the heart of the forest, along the path: over time the falling water has formed a columnar deposit of gray limestone that descends like a drape and that partly acts as a springboard for the jet. But the peculiarity and spectacular nature of this waterfall is the possibility of seeing it even from behind the scenes: in fact, by climbing to the left on a short but steep path, you reach a natural roof of the rock from which you can observe the forest below through the curtain of water, without getting wet! The passage is not protected and is wet, so you need to pay particular attention. Like all torrential waterfalls, it is not always full and active: you need to look for the right period, perhaps after heavy rains, to visit it in all its thunderous splendor.

Point quite easy to reach unless it has rained recently, in which case I would advise caution. Very suggestive view from inside the "Buso"

This path runs along a long and steep edge of the Civillina, but the climb is greatly eased by a large number of hairpin bends (42) and therefore is never difficult or too tiring. It is called the Sentinello because it is nothing more than a mule track that connected all the firing positions of the Great War along its entire length.
