This is a day with many possible variations, and the one shown here is the toughest and best. It's possible to skin straight up to the Refuge de la Blanche via a jeep track which leads from Saint-Véran village but this is only really worth doing if the weather is poor. If at all possible, ski tour to the summit of the Pic de Château Renard and, if skills, conditions and weather permit, ski the North couloir. The line here is drawn taking in the north couloir but if you or it aren't in suitable condition, there's still a lovely ski to be had by skiing south-east from the summit.

Ride the Saint-Véran lift system to the top of the Téléski du Grand Serre and then from there skin up the beautiful broad ridge which leads to the summit of the Pic de Château Renard. Ski south-east off the summit and then swing left and drop into the atmospheric North couloir. It's not super steep (a shade under 40 degrees) and is wide enough that it never feels too technical. Ski down, enjoying every turn, and then when it opens up drift out right and ski down to the foot of a shallow valley. Put skins on again and climb easily up to the Col de Longet.

Ski south-east from the col down lovely open slopes to reach the jeep track from Saint Véran. Follow this easily up to the Refuge de la Blanche via the fascinating Chapelle de Clausis, which is generally locked but looks amazing even from the outside. Pilgrims really must have been dedicated to build a chapel in such an isolated spot!

Speaking of isolated spots, the Refuge de la Blanche is in an amazing position and is surrounded by great looking ski terrain. If you arrive in the hut with time and energy remaining, there are plenty of options for a short tour in the afternoon. Regardless of how you pass the afternoon, enjoy the peaceful ambience of the hut and then get an early night before the crossing to the Refuge Agnel.
