The Krokskogen adventure is the classic long trip through a wild and gorgeous part of Oslomarka. A long walk through Krokskogen is the classic «Nordmarka» tour. Here you will see a protected natural preserve with untouched nature, high peaks and mysterious lakes. And not least, experience the good feeling of being under the stars at night, and feeling the very special atmosphere of the forest. The area is home to stories and legends and the sorceress Gygri (some people think she is still there, in the mountainside). Krokskogen is a part of the cultural heritage and is often mentioned in the Norwegian sagas.
