Departure from Pinsot (Isère)
Starting from the village of Gleysin, from the Bourgeat Noire car park, this beautiful loop in Belledonne connects several iconic sites in the Haut Bréda valley.The route passes by the Chalet du Bout, then climbs up to the Croix du Léat, before descending to the peaceful Lac du Léat, ideal for a quiet bivouac with views of the Chartreuse and the Bauges. The route continues to the Refuge de l'Oule, a small, friendly alpine lodge where you can also spend the night, then descends back to the starting point. We did this hike over two days with a night at the lake, but it can also be done in a day for the more experienced. A beautiful and varied loop, between forests, alpine pastures, open ridges and wild waterways.

The area remains particularly dangerous due to the high risk of further rockfall and falling boulders. Following this incident, the municipality of Saint-Pierre de Chartreuse has issued a by-law to close several hiking trails (for walking, snowshoeing and ski touring). For an ascent of the Dent de Crolles, it is possible to take the route via the Pas de l’Oeille.
