Eissenswelt is a natural limestone and ice cave in the northeast of the Salzburg region. The cave was excavated by natural erosion processes in Mount Hokogel, which is one of the mountains of the Alps chain, and is considered the largest ice cave in the world, as it extends over an area of 42 km, and tourists are allowed to visit the first kilometer only without a special permit. Do not miss the opportunity to visit it, as it is one of the most important natural landmarks in the world!
