Nature’s Ice Palace (Natur Eis Palace) at the Hintertux Glacier is a natural gem, that is an ideal year-round program destination for the whole family. The ice castle is a crevasse, a deep cave-like crack found in a Hintertux glacier. This natural treasure exists due to a regular ice movement.

The glacial cave is unique worldwide, and well-known all over the world. Not surprising, that it's one of the most desired destinations for visitors in Austria.

With its cold natural beauty, the ice Palace fascinates adult glacier fans as well as families with children. The ice cave is open all year round and accessible in all weathers. A visit to the Nature Ice Palace can also be combined with a day of skiing on the Hintertux Glacier or with a view from the panoramic terrace.

You can visit this phenomenon using handrails and steps carved in the ice. On guided tours, you will experience a beautiful world - deep beneath the ski slopes. You are going to discover a glacial cave with magical ice stalactites, giant sparkling ice crystals, frozen waterfalls, and even a glacial lake.

I advise you to wear hiking boots or ski boots as the surface can be slippery. If you are up for kayaking, SUP or swimming, bring extra-warm clothes and towels to warm up after the fun.

Walking Path Description

The underground castle was carved out of snow and ice by nature over time. The accessible section of the glacial crevasse was divided into various parts. Later, it was partly extended with stairs and ladders.
The entry to this hidden complex of caves and tunnels is a spectacular experience. You pass through a giant hall of sparkling turquoise ice into the center of the hidden gem.

After you put on the safety helmet, a safety harness, and a rope, you are going to plunge deeper into this fascinating natural wonder. You will immediately forget that you are under the slopes of the ski resort. This encapsulated world takes you through crystal chambers and sparkling ice crystals.  You will spend apr. 60 minutes among the eternal ice, in the unique natural phenomenon.

You will pass hundreds of frozen waterfalls across your way, reaching a glacier lake, and an ice chapel lit up in red.

The further you go along the walkway combined with up and down ladders, the more adventurous your journey will be. Many jaw-dropping moments await you.
During your way, you will pass the 15 metres deep glacial chamber, which is located 25 meters below the ski runs.

Probably the most mentionable highlight of the crystal chamber is the floor, which is actually a frozen glacial lake! Bring non-slippery boots with you.


A glacier is never pausing; it always moves and adjusts its shape. No matter if these magnificent ice halls and ice rooms are located twenty-five meters below the surface, no one can foretell how long the ice castle will be there - and open for visitors.

Don't miss out the ice formations, the endless ice formations, the stillness, and calmness of this hidden beauty!  A visit to the ice palace should not be missed.

Take a look at more day activity in Zillertal. Skiing, guided ski tours, or even ice climbings are available with professional, state-certified ski and mountaineering guides.
