Glacier - Rosazza-Savoie Bivouac

Just before you get to Glacier, in the municipality of Ollomont, take route 3, near the crossroad between the paved and dirt roads, which goes up to Pont, Crottes then continues to By where it turns left near a church and heads for the small wall that acts as a barrage. Cross it and head for a farm road, which winds several times then leads to the Porchère alp (2102 m). Continue along the route that starts at the dwellings, and, after intersecting the same road several times, leads to Tsa di Porchère (2290 m). The trail that turns off from the alp leads to the Rosazza-Savoie bivouac.
