Col d'Izoard

Col d'Izoard is a mountain pass in the Alps at an altitude of 2,361 m. It is connecting Briançon on the north and the valley of the Guil in Queyras, which ends at Guillestre in the south. There are forbidding and barren scree slopes with protruding pinnacles of weathered rock on the upper south side. Known as the Casse Déserte, this area has formed a dramatic backdrop to some key moments in the Tour de France, and often feature in iconic 1950s black-and-white photos of the race. From the south, the climb starts at Guillestre from where it is 31.5 km in length, at an average gradient of 4.8%. The climb proper starts at the junction with the D947, near Chateau Queyras from where the ascent is 15.9 km long. Over this distance, the climb gains 1,095 m at an average of 6.9% and a maximum gradient of 10%. The climb from Briançon to the Col is 20.0 km in length, climbing 1,141 m at an average gradient of 5.7 % and a maximum gradient of 9.4%. In general, the col is closed from October to early June.
