Chartreuse sector
Outside the PDIPR network of Pays Voironnais, access to the Grande Sure via the Pas de la Miséricorde passage is prohibited by municipal decree. In fact, a geotechnical study carried out in 2010 had detected significant unstable rock masses with a very high risk of failure. A new landslide in September 2025 served as a reminder of the danger of this passage. We recommend taking the Grapillons passage described in the guidebook The Grande Sure mountain pasture – OT Pays Voironnais.
