Hidden within the Austrian Alps near Werfen, Eisriesenwelt is one of Europe’s most extraordinary natural attractions. Its name means “World of the Ice Giants,” and the frozen landscape inside the mountain certainly lives up to that description. Known as the world’s largest ice cave, Eisriesenwelt combines enormous underground passages with spectacular ice formations created naturally over thousands of years.
