Etna lava caves
Etna’s caves are natural formations that are created during the eruption.
As the magma flows, we notice a cooling on the outside that reduces the flow until it stops, but in the inner part instead happens the reverse process. The magma becomes more and more liquid and flows much faster. At the end of the eruption, this process causes the solidified part to remain perfectly as it had stopped, but the inner part empties completely creating these tunnels.
Most of these caves are visitable, it is recommended to always do it with an experienced guide. Consider that they have lengths ranging from 50 meters up to 1 km, and several meters deep.
Centuries ago, the people of Etna used the caves of Mount Etna to store snow. Then with the mules the ice was transported to the villages and from this were born the delicious granite!
