Nestled in the Tennengebirge mountains and beautifully overlooking the charming little town of Werfen south of Salzburg, the Eisriesenwelt cave means “the World of the Ice Giants” in German. This gigantic cave is home to a remarkable natural and geological spectacle created when the water of the Salzach River meets the karst rock of the Salzburger Alps. The formation of the Eisriesenwelt cave dates back to the Tertiary era, several tens of millions of years ago, well before the prehistoric period.
The Eisriesenwelt cave is located at an altitude of more than 1,600 metres and contains sprawling labyrinths that run deep into the Prealps. Water from melting snow manages to flow into the mountain through cracks and crevices before dramatically refreezing. Guided tours offer the opportunity to admire impressive natural ice formations (ice chambers and walls, ice waterfalls, ice sculptures, giant stalagmites, ice crystals…) enhanced by a clever play of light. This abyssal network of galleries gives the Eisriesenwelt the title of the largest ice cave in the world.
The cave was revealed to the public in 1879 by the Austrian naturalist Anton von Posselt-Czorich, who ventured to walk the first 200 metres. However, it was not until the beginning of the 20th century that the 42 kilometres of underground passages in the Eisriesenwelt began to be explored (only the first kilometre of the cave is accessible to the public today). It was thanks to the research work of Anton von Posselt-Czorich that the speleologist Alexander von Mörk, together with other pioneers, became interested in this little-known site in 1913. As the Eisriesenwelt began to gain regional importance, the first visitor facilities (including primitive climbing routes and a refuge) were built. An unpaved road was built in 1953. Two years later, a cable car was laid out by the Austrian authorities to make it more accessible. Today, the Eisriesenwelt is one of the most visited attractions in the Salzburg region, along with the nearby Hohenwerfen Castle. As the cave is owned by the Austrian Federal Forests, part of the revenue generated from visits is used to preserve and protect the surrounding forest area.
