Many people come to see it every year. About 200,000 tourists visit the cave annually.

How does a cave like this form? The Salzach river helped make it. The river wore away the limestone rock. This created long passageways through the mountain. The ice inside forms in a special way. Snow melts and drains into the cave. During winter, chilly winds blow inside. These winds freeze the snow into ice. In summer, cold wind blows out of the cave. This keeps the ice from melting away.

People did not always know about this cave. Local people used to be afraid of it. They thought the cave was an entrance to Hell.

Anton Posselt was the first to officially find it. He was a scientist from Salzburg. He explored the cave in 1879. He only saw the first 200 meters. Later, a man named von Mörk led more trips. He began his work in 1912. He died in World War I in 1914.

Many things have changed since those early days. In 1920, people built a cabin called Forscherhütte. They also made paths from Werfen and Tenneck. A cable car was built in 1955. This ride takes only 3 minutes. Before that, the climb took 90 minutes. Today, the Salzburg Association of Cave Exploration manages it. They have leased the cave since 1928. The Forest Commission still gets some of the fees.

Walking through the cave is like a journey.
