FATMAP difficulty grade
##Ascent From the SBB station (park along the road, direction Vallée de Joux), go through the underpass to the refugee centre, and follow the road until about 880 m.
Then take the path on the left to climb the côte de Prailoux, through the forest to the pasture of the same name. Then go up to Prailoux on it by the "road" and pull NE in the valley to reach the CAS hut. Cross the border wall and follow the ridge (not passing to the right of the fence, there are always monstrous ledges) to the top, recognizable by its barrel! ##Descending By the same route to Prailoux below, then follow the "road" to Vallorbe.<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
