Route North / South

↗ 1576m ↘ 1783m

After crossing Briançon, the route climbs rapidly up towards the Col de l'Izoard pass (2360m), via Cervières, for c.19km, at an average gradient of 6.5%. The slopes are relatively regular. Approaching the top, as you ride past the Refuge Napoléon, you’re only 1km from the summit.  After the Col de l’Izoard, you enter the Queyras area, crossing the extraordinary geological formations of the Casse Déserte. Continuing on, enjoy exploring this splendid traditional mountain area, declared a Parc Naturel Régional. Stop off at Arvieux and Château-Queyras before descending to Guillestre, set on the edge of the Forêt Blanche ski area, which includes Risoul + Vars.

Route South / North

↗ 1783m ↘ 1576m

From Guillestre, on the edge of the Forêt Blanche ski area, which includes Risoul + Vars, cycle via Château-Queyras to Arvieux. Crossing the Queyras Range, protected as a Parc Naturel Régional, you reach the foot of the difficult climb to the Col de l'Izoard pass (2360m). While you may have found the first 17km of this stage from Guillestre easy, that won’t be the case with the ensuing 15km, the stretch at Brunissard punishingly steep. A few hairpin bends further up, you cross the extraordinary geological formations of the Casse Déserte, before taking on the final two kilometres, which prove exceptionally challenging. After passing in front of the Refuge Napoléon, enjoy the lovely, steady 19km descent via Cervières to Briançon.
