The Grotta del Gelo (Ice Cave) is one of 200 lava tubes which are known on the flanks of Mt. Etna. This one is located high up above the upper circle road at about 2,000m asl. Because of the heigth the average tempperature is rather low and ther is frost and snow in winter. The cave has its opening uphill and is closed by a collapse at the lower end. As a result cold air is trapped in winter and melting water flowing into the cold cave in spring freezes. The ice stay in the cave all over the year, and so the cave is said to cointain the only glacier in the Mediterranean Sea.
The cave is open to visitors but not developed. As it is nacessary to hike to the entrance visitor generally have the right clothes and shoes for a visit. It is advisable to take a lamp, a helmet and warm clothes with you if you plan to visit the cave.
