The road, starting at Rives, runs peacefully through the plain before increasing slightly in altitude and winding between valleys and forests.
After passing through the villages of St Blaise, St Nicolas de Macherin and St Aupre, the gradient is a little tougher but as you approach the pass, it soon becomes wider and very pleasant. As you ascend at a gentle pace, enjoy the superb views of the Chartreuse, Mont Blanc and the region of plains and hills.
Just a few more kilometres and you’ve arrived at the famous Croix des 1000 martyrs (Cross of 1000 Martyrs), which is the end point of the pass. But what is the origin of the legend associated with this place?
Legend has it that 10,000 soldiers, not 1000, suffered great cruelty and were martyred by 30,000 soldiers of the Roman Army on 22 June 120. It is said that their relics were brought back to a monastery in the region. A story worth delving into. Go back via the same itinerary to enjoy the freshness of the forests along the way.
