The Col de la Croix de Fer from Saint-Jean-de-Maurienne is 28.2 kilometers with an elevation gain of 1475 meters. The average gradient is 5.23% with maximum gradients of 9.6%

View of Mont-Blanc

Highlight • Summit

A few meters above the top of the pass there is an installation made up of four stone steles - these mark the view of Mont Blanc, which can be seen from here when the visibility is good. The few meters up can be covered with racing bike shoes with due caution.
