There are three different ways to climb to the top of the Col de la Croix de Fer. The most famous is the climb from the Verney dam in the Oisans valley, because it is the slope used in the Marmotte (except the last kilometers). It is 27.5 kilometers long with an elevation gain of 1292 meters. The average slope is 4.7% with maximum slopes of 11.1%.

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%

The final ascent is via the Col du Glandon. After the summit of Glandon it remains approximately 2 kilometers to the summit.
