The Ice Cathedral

Currently inaccessible because entirely buried under the snow

This ice cave delights lovers of atypical landscapes and photos, who can access it easily, but under their own responsibility.

Also called "the Mill" or "the devil's hole", the natural ice cave of Glacier 3000 was created as a result of a syphon effect. In spring and summer, this cavity fills up with water. The melting ice and the accumulation of residues block the evacuation and thus a lake is formed.  In autumn, the plug disappears, the water spins out as in a syphon (hence the name "Mill") and gives way to a cave, which is different from one year to another. This natural cave of about twenty meters long is a unique show, the lights are reflected on the ice walls and give images from another world.

Access under everyone's responsibility

The cave can be reached in 15 minutes from the bottom of the Ice Express chairlift. A signposted path will take you safely to the cave. Its location is indicated but its access remains under everyone’s responsibility. The ground being made of ice, it is important to visit it with caution. The uncertainty of the weather during the winter and the accumulation of snow in front of its entrance, do not guarantee its accessibility during all the season. It is very rare to be able to visit such a cavity, so you should not wait too many time to plan you visit.
