Aeroporto "Corrado Gex" Saint Christophe (Aosta).
From the Aosta Est exit of the motorway, go towards the City of Aosta. Soon after the Corrado Gex airport turn right toward the Village of Saint Christophe (615m). Follow the signs for Sorreley (790m). Past Sorreley, continue to the Village of Parleaz (1.214m) and on to the Village of Blavy (1.471m). (Be warned that the road, although paved, is very narrow and twisty).
Park at the beginning of the dirt road (which is accessible only to authorized vehicles). Hike along the farm road that leads to the Praperia Pastures (1.737m). After about 10 minutes the road forks: keep right and reach the Viou Pastures at 2.062m after about 1h'30. Right behind the pastures starts the well-marked trail for Colle di Viou (2.716m): a comfortable fixed Bivouac "Penne Nere" (2.730m) was opened recently (Jul 16th, 2005) near the saddle. The wooden building sleeps 14 and can be reached in about 2 hours from the pastures. Keep right (southwest) and once past the initial grassy slopes start the ascent of the rocky ridge staying on the north side of the mountain a short distance from the crest. Climb a few easy slabs and short cliffs to reach the Summit of Mont Mary, marked by a small cairn. Total ascent time from the start of the dirt road is 3h'40/4h'30. Elevation gain: approximately 1300m.
ALTERNATIVE DESCENT ROUTE: descend northwards from Col di Viou: after the Lac d'Arpisson (2.480m) (enchanting reflection of Grand Combin) follow towards Fouillou Ruines (2.092m), Alpe Neuve (2.026m), Arpisson (1.882m). A further long descent will lead you to the valley bottom, not far from Valpelline (1.022m).
This route is an easy walk-up except for the last stretch from the bivouac to the summit, which may be tricky if there is snow.
Normal hiking equipment. A short rope is recommended for the ridge if there is snow.
