A Geological Marvel
The formation of Eisriesenwelt Cave began nearly 100 million years ago when the Salzach river carved through the mountain, eroding passages and creating cracks and gaps in the limestone. These gaps grew larger over thousands of years, allowing snowmelt to seep into the cave and freeze in the lower, colder parts of the caverns. This process created the breathtaking ice patterns that visitors can see today.
A Journey Through the Ice Giants
Visitors to Eisriesenwelt Cave can explore its icy wonders through guided tours. The journey begins at Posselt Cave’s entrance and passes through Posselt Hall and Posselt Tower before concluding at Hymir’s Castle. The cave is only accessible via guided tours, which are typically part of scheduled excursions from Salzburg. These tours often include transportation and entrance to the cave, as well as visits to other nearby attractions such as the Golling Waterfall, the Salzwelten Hallstatt salt mines, and the Hohenwerfen Castle.
Eisriesenwelt Cave remained virtually unknown until the end of the 19th century due to its isolated location and the lack of interest in cave exploration at the time. It wasn’t until 1879 that the cave was discovered by a Salzburg-born naturalist named Anton von Posselt-Czorich. Posselt’s discovery was published in a climbing magazine, but the cave quickly faded into obscurity.
In 1912, a speleologist from Salzburg named Alexander von Mörk led multiple expeditions into the caves, sparking renewed interest in the cave’s natural wonders. As more people became aware of the cave’s beauty, its popularity as a tourist destination grew. The first ascent routes to the cave’s peak were developed in 1920, and the construction of the Forscherhütte explorers’ cabin soon followed. The Dr. Oedl House, a second cabin, and pathways from Werfen and Tänneck were also built to accommodate the increasing number of tourists.
