❄️ Ice Cave Werfen (Eisriesenwelt): World’s Largest Ice Cave Near Salzburg
Step into a natural wonder just south of Salzburg. Ice Cave Werfen (Eisriesenwelt) is the largest ice cave in the world and a must-see in Pongau. Even on hot summer days, you enter a wintry world of glittering halls and tall ice rooms. It feels new and exciting. The visit also fits neatly into a Salzburg day trip.
🧊 Why Ice Cave Werfen is a top sight
The cave labyrinth reaches more than 42 km into the Tennengebirge. Visitors explore only the first kilometre on a guided tour. There you see giant ice forms that look like natural palaces. In summer the air stays close to 0 °C, so wear layers and sturdy shoes. From the valley you can spot the entrance about 20 m wide and 18 m high, which hints at the size inside.
🧪 A 100-million-year story (how the cave formed)
The rock story of Ice Cave Werfen began around 100 million years ago. Tectonic forces lifted and cracked the limestone. Over long ages, water seeped through the fractures. It dissolved the rock and washed grains away. Bit by bit the voids grew into vast passages. Many Alpine caves still change today. Yet parts of Eisriesenwelt have dried out, so big sections now evolve very slowly.
🔬 Why there is ice here
Eisriesenwelt is a dynamic ice cave. Lower entrances and higher openings create a chimney that moves air through the mountain:
- Winter: Outside air is colder and heavier. It sinks into the lower galleries and chills the rock below freezing.
- Spring: Meltwater drips into these cold zones and freezes, building columns, curtains, and wave-like shapes.
- Summer: Airflow flips. Even so, the interior stays cold enough to preserve much of the ice.
👣 What to expect on a guided tour
- Guided only: Tours cover the first 1 km and last about 70–75 minutes.
- Serious steps: Expect steep walkways and many stairs – pace yourself and pause as needed.
- No photos inside: Focus on the formations and the guide’s stories.
- Chilly, always: Dress warmly and wear grippy shoes, even in July.
- Views outside: Before and after the cave, enjoy broad panoramas over the Salzach Valley.
