Grotta del Vento (Wind Cave) has three natural entrances, at an altitude of 600m, 800m and 1400m asl. The height difference between the entrances and the temperature difference between inside and outside, create a convection stream of air! In winter the cave is warmer than outside, and as the warm air is lighter, it leaves the cave through the upper entrance. In summer the cave is colder than outside, and the cool air being heavier leaves the cave through the lower entrance. The speed of the air depends on the temperature difference between external and internal air. This stong air current is the reason for the name of cave.

At first only a narrow crevice was known, called Buco Soffiante (Blowing Hole) because of the air current. The cold air leaving the cave was used as refrigerator simply by building a hut on top of the crevice. The air temperature of 10°C is not low enough to cool food, a cellar would do the same. But the cavern air has much more carbon dioxide than outside air, and reduced oxigen. This added a second preserving effect and made the hut as effective as modern refrigerators. The hut from the 17th century existed until the beginning of World War II.

The lowest entrance of the cave system is the entrance for the cave tours. During tours an armoured door blocks the air current almost completely. This has about the same effect as the original situation around the entrance. A small brook, dry in summer, becomes a torrent each spring and filled the cave entrance long ago with rubble and earth. So only a small gap at the ceiling of the passage remained. This passage was often blocked, or extremely narrow, which made it difficult to explore.

The cave was first entered by a little girl, forced to do so by some local boys. But even the little girl was not able to crawl in very far. In 1932 the gap was widened by a flood, and an expedition of speleologists was able to get into the cave to a deep siphon. But they were not able to cross it, so the exploration ended after 70m. The cave seemed to be little promising.

How much they erred was discovered in 1961, when another expedition tried to enter during low water. The siphon had fallen dry in this year and it was easy to wade through. The speleologist explored 600m of the cave on this first tour! Now the dam was broken, huge parts of the system were explored and soon the idea came up, to open the cave to the public. This required a way to avoid the siphon, so an artificial tunnel was built high above high water level.

A second important problem was the gravel in the entrance section. It was removed to built the path, but in 1996 a flood destroyed the entrance section, filled it with gravel, and destroyed the nearby ticket office. The entrance was reopened with bulldozers, a new ticket office built, but to avoid repeating destructions during future floods, the whole entrannce sectio was redesigned and protected by a massive concrete wall. This dam diverts the nearby brook and leads it directly into the valley

The developed part of the cave shows three totally different cave sections. The first one has numerous beautiful speleothems, stalactites, shawls, and cave pearls. The second one is lower, at the bottom of a 45m deep pit, and sometimes water filled. It has no calcite speleothems but rather rare clay dripstones. The third part is above the entrance siphon. The narrow path winds up a steep and ragged shaft and shows an astounding vertical section of the cave.

There are three cave tours, which last one, two and three hours. The short tour shows the speleothem-part, the two hour tour shows also the lower part with the clay dripstones. Only the three hour tour shows all three and really recommended for everyone who has enough time.

Most caves in Italy prohibit taking pictures with flash. But this cave is a honorable exception: they allow photography, as long as it does not disturb the tour. The cave is frequented very much by visitors, many of them from foreign countries. So tours are guided in several foreign languages like German, English, and French.
