Lunsen is one of Sweden's finest areas of orienteering that you just have to experience. The terrain is as it's if taken from a fairy tale with a myriad of small-cut heights, mosses covered by tussle frames and pure-lined cliffs.
Despite its nearness to Uppsala, Lunsen consists largely of untouched wilderness. In the northern part and in the area around the arena there are a large number of paths that will be used for the MTBO courses.
Stage 4 for MTBO is a long distance.
