Posettes Loop (BLUE) Col des Posettes 17km 750m/-850m. From Chamonix take the number 2 bus to Argentiere and then change on to the number 21 to Col des Montets.
Do not be tempted to use the main road as it is very busy with blind bends. From Col des Montets the route descends through meadows to Vallorcine.
From Vallorcine there is a steady climb following the ski pistes to the Col des Posettes, before heading down towards Le Tour.
From Le Tour you can follow the road back to Montroc, and on to Argentiere if you wish, or follow the routing along the river trail, which has one steep rocky pitch.
The routing is non-technical but fairly long hence the Blue rating. (GPS routing starts at the Col des Montets and ends at Montroc Day8Posettesloop.gpx).
