A selection of ice caves from around the world, from the largest in Germany to arguably the weirdest in California (well, it would be, wouldn't it?). One of the strange facts about some of these caves is that the ice does not melt in the summer, but it does in the winter.
Size, of course, is not everything but let’s start with the largest ice cave on the planet. Translated from the German, the name of the cave is the ‘Word of the Ice Giants’ and to be frank, it is not a piece of Germanic overstatement. Forty kilometers south of Salzburg, Austria in the Hochkogel Mountain the cave stretches for more than forty kilometers. However, the more than two hundred thousand visitors the cave receives each year are restricted to the first kilometer only.
