Les Bossons

Climbs 258 – Rocktype Granite – Altitude 1140m a.s.l – Faces ?

Crag features
Several marked boulder circuits (yellow to black) on the polished granite boulders beneath the Glacier des Bossons. Excellent for a hot Summer's day as the site is sheltered beneath trees. Mostly good landings, though a crash mat is a good idea. Some of the taller boulders with no easy descents have lower-off bolts!

Note. Some of the boulders in August 09 were quite mossy following the prelonged snowfall of the 08/09 Winter (they're generally under snow from December until April).

Access notes
Take the Les Bossons turn off on the N205. Follow the Route des Rives leading up the hill, past the Gite la Cremerie du Glacier. At the road junction take the Chemin du Cerro and follow this upwards (past 4 junctions) until it finishes at a small parking area 20m before a large pylon. The first boulder is a 1 minute walk through the trees, on the left of the main path.
