Col d'Izoard


Col d'Izoard is a mountain pass in the Alps in the department of Hautes-Alpes in France.
It is accessible in summer via the D902 road, 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 featured in iconic 1950s black-and-white photos of the race.

Tour de France

The Col d'Izoard is frequently on the route of the Tour de France, where it is frequently classified as an Hors Categorie climb.Warren Barguil won the 2017 Tour de France's Stage 18, becoming the first cyclist to win a Tour de France stage that finished on the Col d'Izoard - it has been on the route 34 times previously in the Tour de France since 1922 but never before had a stage finished there.
Several of the Tour de France's more memorable moments have occurred on the Col d'Izoard, particularly the exploits of Fausto Coppi, Bernard Thévenet and Louison Bobet. A small cycling museum is at the summit, along with a memorial to Coppi and Bobet.
