The Devil's Nest, the deepest ground erosion in Europe

Finland has the deepest karst failure in Europe with a depth of 23 meters, called the Devil's Nest. It's creation took more than 1 million years and went through 4 ice ages. Glaciers moved the rock and filled the hole with granite, sand and other materials. All this was cleared at the end of the 20th century and the failure opened to visitors.




The temperature at the bottom is significantly different from the surface and this created its own special microclimate.




A 21-meter tower was built near the failure, it can be climbed.






Opening hours: from May to August, from 12 to 20.

Getting there: only by car, parking N 62 23.935 E 22 53.785. The last sections of the road are dirt and very dusty.
