The Col de la Croix de Toutes Aures, often referred to as the Col de Toutes Aures, is a road pass on the Chambaran plateau on departmental road 518, located in the Isère department at 628 m altitude. Its name means "passage of all horizons" or "all winds" because its dominant position on the Chambaran plateau subjects it to numerous and changing wind currents, coming from all sides. In France, there are two other steps "de Tous Aures". The first is in the Alpes de Haute Provence and connects the Var valley with Lake Costillon. A second is located in Isère, in the foothills of the Vercors and connects Choranche with Presles. This pass is the meeting place for cyclists and hikers with the start of the Brion walk.

The Col du Buis, culminating at 1196 m, was a mule pass which was paved in the early 2000s and it must be believed that the DDE services did not look for an alternative to soften the slope, especially on the North side. from the hamlets of la Serre and les Venières. Because the pass simply displays an average of 10.6% over almost 4km, with ramps climbing to 17-18%! As much to say to you that you will pass the 4kms which will appear among the longest of your life... It is a really hard climb, which offers little respite. It is difficult to appreciate the landscape of this small wild pass. This is probably the reason why everyone only takes the picture once they have reached the top...
