||St. Jean de Maurienne
This high mountain pass is located in Savoie, France in the Auvergne-Rhône-Alpes district of the French Alps. Col de la Croix de Fer stands at an elevation 2,067 m (6,781 ft) and connects the southeastern villages of Le Bourg-d'Oisans and Saint-Jean-de-Maurienne. There’s a lot of contrast when it comes to difficulty of this pass - because the incline and the decline of the road varies depending on route is taken. The classic west side approach will take you through the beautiful Lac de Grand Maison; it has two vertical stretches and two declines. Col du Gladon is a less challenging route (a short 200 meter decline) and is located on the edge of Col de la Croix de Fer. The east region of this pass is a least favorite for cyclists (due to the high mountain hairpins and having a bit of traffic during certain times of the day), but there’s a variation in this route and if travelers take a right turn after exiting the three tunnels - it puts you on a route marked St-Sorlin-d’Arves & Panoramique, which is exquisitely panoramic and serene.
