This is a challenging track for mountain lovers, you will discover swiss landscape through roads, villages and pastures. First part is going up for 1km on a road through old villages to join Champoussin. You will then continue through a quiet forest path. After crossing the road, you will arrive at the place known as "Sur Crête" and run up to reach a beautiful but steep ridge. The place "Frachette" is a nice place to take a break, you can pic-nic there. The run continues along the ridge for 3km. Then the road through the forest is taking you to Champoussin. A technical way down is the last part of this run, just before reaching the road and arrive at the Crosets village.
