Eisriesenwelt–The World’s Largest Ice Cave

Apr 12, 2012 4 comments

The Eisriesenwelt (German for "World of the Ice Giants") is a natural limestone ice cave located in Werfen, Austria, about 40 km south of Salzburg. It is the largest ice cave in the world extending more than 42km.

Eisriesenwelt Cave was created by the Salzach river as it flowed through the mountain eroding passageways nearly 100 million years ago. Over the course of thousands of years cracks and crevices in the limestone became more developed as water eroded the rocks away. In winter, when the air inside the mountain is warmer than outside, cold air streams into the mountain and reduces the temperature of the lower areas of the caves to below freezing point. In spring the water from melting snow seeps through the cracks in the rock and when it reaches the colder lower areas of the caves it freezes and turns slowly into the wonderful ice formations visible inside the caves.

Although the cave has a length of 42 km, only the first kilometer, the area that tourists are allowed to visit, is covered in ice. The rest of the cave is formed of limestone. Since the entrance to the caves is open year-round, chilly winter winds blow into the cave and freeze the snow inside. In summer, a cold wind from inside the cave blows toward the entrance and prevents the formations from melting.

Eisriesenwelt was discovered by Anton Posselt, a natural scientist from Salzburg, in 1879. Before his discovery, the cave was known only to locals, who, believing that it was an entrance to Hell, refused to explore it. One year later he published a detailed report of his discovery in a mountaineering magazine, but the caves then slipped back into obscurity.

Alexander von Mörk, a speleologist from Salzburg, was one of the few people who remembered Posselt's discovery. He led several expeditions into the caves beginning in 1912, which were soon followed by other explorers. In 1920, a cabin for the explorers, Forscherhütte, was built and the first routes up the mountain were established. Tourists began to arrive soon after, attracted by the cave's sudden popularity. Later another cabin, the Dr. Oedl House, and paths from Werfen and Tänneck were constructed.

Today the Eisriesenwelt cave is visited by around 200,000 tourists every year.

  2. I wish there would be more facts on why it's such a tourist attraction. Plus the pictures could be more dedicated to showing frozen waterfalls and others?

  4. Unfortunately you are not allowed to take pictures while you're inside. But it's a nice place. And the surroundings too!
