Eisriesenwelt cave, Werfen, Austria

The Eisriesenwelt is the largest ice cave in the world, located near the town of Werfen in the Austrian state of Salzburg. Nestled in the Tennengebirge mountain range of the Alps, the cave system extends for more than 42 kilometers, although only about one kilometer is accessible to visitors. Formed naturally over thousands of years, the cave is renowned for its spectacular ice formations, including frozen waterfalls, ice stalagmites, and massive chambers of glistening blue ice.

Visitors typically reach the Eisriesenwelt by a combination of car or public transport and a short ascent via a cable car followed by a steep walk up to the cave entrance. From Salzburg, the drive takes approximately 40 minutes along scenic alpine roads, while regional buses connect Werfen to the cave during the tourist season. The path to the cave entrance offers panoramic views of the surrounding mountains and the Salzach valley, enhancing the visitor experience even before entering the cave itself.

From the car park it is a 20-minute walk to the cable car, and another 20 minutes from the upper station to the cave entrance; inside, the tour climbs and descends about 1,400 steps.

In 2026 the cave is open daily from 1 May to 1 November, with tours between 9:30 a.m. and 3:45 p.m.; it is closed in winter. Guided tours last around 75 minutes and are required to ensure safety and preserve the delicate ice structures. The combined ticket for the cable car and the tour costs €45 for adults at the cash desk or €41 online, €32 or €30 for young people aged 15–18, and €24 or €22 for children aged 5–14. Online tickets come with a 30-minute arrival slot. Warm clothing and sturdy footwear are strongly recommended, as temperatures inside the cave remain around 0 °C, regardless of the season, and photography is not allowed in the cave.

Eisriesenwelt is famous not only for its sheer size but also for the ethereal beauty of its ice sculptures, which change and evolve with the seasons. The cave was first discovered in 1879 by the explorer Anton Posselt, and it has since become one of Austria’s most iconic natural attractions. Its combination of geological significance, visual spectacle, and alpine setting draws tens of thousands of tourists each year, making it a highlight of any visit to the region.
