Beautiful and imposing summit located in High Valle d'Aosta, Grande Rochère is the meeting point of three large ridges, which travel in the NE, NO, and SSE directions. The views from Grande Rochère cover the entire Region of Valle d'Aosta. The vista of Mont Blanc, rising in all its majesty between Aiguille des Glaciers and Mont Dolent, is justly famous. Grande Rochère is not well known because it is difficult to see from the valley floor.

Different Views of Grande Rochère
The initial part of your approach depends on where you are coming from:
From Torino, Milano, etc: Motorway A5. Exit at Morgex.
From Switzerland: through the Grand Saint Bernard Tunnel or the namesake pass.
From France, through the Mont Blanc Tunnel or Petit Saint Bernard Pass: It is not necessary to take motorway A5: you can drive on SS.26, in the direction of Aosta.
From the Morgex exit of Motorway A5, continue east for about 1.5 km along state route n° 26 in the direction of La Salle (994m). Take the main street of La Salle and continue along the Regional Route leading to the small Village of Morge (1.625m). After a few switchbacks, and past the Villages of Chatelard (1.061m), Remondey (1.349m) and Morge (1.625m), arrive to Planaval (1.750m), where you leave the car.

Grande Rochère and Bonalé Pass seen from the SW ridge of Aiguille de Bonalé
From the Village of Planaval hike east taking the pack trail that goes up steeply and diagonally. Go past the Pasture of Montagna Casa Bianca (1.871m), climb the following small hanging valley, surmount a steep slope marked by streams, and reach the Rantin Pasture by a wide diagonal road (2.238m, 1h'00 to 1h'30min).
Head west for about 1.5 km, reaching the Pra Barlet Pasture and the Bonalé Hut (2.340m). Cross the floor of the hanging valley on a faint trail, aiming for the grassy slopes to the left of a characteristic beak-shaped promontory above a cliff. Continue in a gully with light-colored rocks aiming for the shoulder that comes down directly from Petite Rochère (not for the scree-filled gully). Past a couple of steep slopes made of calcoschists and grassy turf, reach a faint but very scenic trail that leads, through scree and patches of snow, to the col between Grande Rochère and Petite Rochère. From there, climb scree and broken rocks to reach the summit in about 30 minutes. The route is not difficult, but steep and the trail is discontinuous. The summit trigonometric marker (3.326m) is visible from below. (Three hours from Bonalé Hut; five hours from Planaval.)
From Planaval (1.750m) descend briefly to the bridge and walk along the dirt road along the stream. At first the road is almost flat, and then it goes gently uphill till it reaches the Pasture "Les Eculés" (1.880m). From there, a nice view can be had to the east of the waterfalls. Continue on the trail along the stream to elevation 2.083m, and then surmount a steep gully leading to Alpe Bonalè (2.340m).
It is currently the most frequently used variation. Climb further left (south) the gully between Petite Rochère (3.267m) and Mont de la Varise (3.006m). The gully leads to a saddle (2.990m) with a safer route. From the saddle, an easy climb takes you to Petite Rochère. Keep east and descend on steep rocks to the notch about 100m below. From the notch, continue along the route that leads to Grande Rochère.
The route is rated EEA/F+.
Standard mountaineering equipment.
Remember that free camping is forbidden (except for emergency reasons, above 2.500m, from darkness until dawn).
