The ice cathédrale

A new all-natural attraction becomes available at Glacier 3000: the Ice Cathedral.

This ice cave delights lovers of atypical landscapes and photos, who can access it easily, but under their own responsibility.
Also known as "the Mill", 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.
