Roc du Blanchon Map

The Roc du Blanchon is a 2747m summit which gives a great day tour in its own right from Pralognan, or an easy day on the way in to or out of the Roc de la Pêche refuge as part of a multi-day tour in the Vanoise. The route described starts from the spring-time parking which is normally just before the Pont de Gerlon. In the winter months the start will be made from Pralognan itself, following the cross-country tracks to reach the same point, adding 2 kms and 150m of extra uphill.


From the Pont de Gerlon follow the main road to just beyond the obvious gorge of the Torrent des Nants (opposite the hamlet of Les Prioux) - head generally south-east from here up Les Béveriers (some bush-whacking may be necessary depending on snow cover) trending slightly rightwards until at about 2200m you enter an open bowl - follow this to the summit. The views onto the west face of the Dome des Nants and over to the skyline above the Roc de la Pêche are great and worth the effort on their own.

It is also possible to reach the summit by following the Nants valley - for this break left at either 2000m or 2100m (look for the claw of rock) as you skin up Les Béveriers. Follow the general line of ascent on the way down. Although north-west facing it is usually possible to play with the aspects to find cold snow. If you are going to (or coming from) the Roc de la Pêche) then you can hang a left at about 2200m and take a diagonal line toward the Plan des Bôs and Montaimont to then cross the river a few hundred metres upstream, with a very short climb out to the refuge.



Slopes become slightly steeper at around 25-30 degrees.
