The Grotta della Volpe is a classic example of a lava flow cave on Etna on the lavas of 1892, the same ones that originated the Silvestri Craters. The peculiarity of this cavity, which makes it interesting to visit, is the consistent recirculation of fresh air that can be felt even outside especially in the summer period and the presence of animal bones at the bottom of the cave, presumably the remains of a fox's banquet, hence the name given. The lava tube winds for 82 meters on a single channel. The entrance is made up of the ephemeral mouth of the lava river and is easily accessible. The bottom is made up of AA type lava. After about twenty meters there is a concretion of translucent white minerals. More or less after having traveled 50 meters from the entrance there is a collapse that has thinned the vault to the point of creating an air passage that creates the recirculation we spoke about above. After having overcome a narrowing of a few meters, the vault rises back up to its average height of a couple of meters. Nearby there are other similar caves detected and inserted on the Open Street Maps by the same authors, among which we point out the Grotta dei Penitenti, included in the census and the Grotta Garbage, a small cavity in which unfortunately there are several bags and plastics, transported by the wind, from the Rifugio Sapenza.
