The Col de la Croix de Fer (2,067 meters) connects the Isère and Savoie regions. The area – on both sides – attracts many cyclists, as there are many famous climbs to be found, besides this one.
In Isère – centered around Bourg-d’Oisans – these include the Lautaret, Les Deux Alps, la Bérarde and “the most famous of them all”, the Alpe d’Huez.
In the Savoie region, centered around Saint-Jean-de-Maurienne, you’ll find – among others – the Glandon, Télégraphe / Galibier and the Madeleine.
At the time I published this page, the Croix de Fer had featured in the Tour de France 17 times since 1947, most recently in 2017.
In 2015 it was included in 2 stages: stage 19 via the Col du Glandon from la Chambre and stage 20 from Saint-Jean-de-Maurienne.
The latter stage was the result of an alteration, since the original stage route over the Télégraphe / Galibier was blocked because a landslide had made descending the Lautaret unsafe.
In stage 18, the climb from Rochetaillée was included too, but that took the left turn over the Glandon…
