Les Grandes Jorasses is one of the most famous peaks in the Mont Blanc Massif, rising to 4,208 m on the border area of Italy and France. It is best known for its dramatic north face, steep ridges, and serious alpine character. The mountain is a major objective for experienced climbers rather than casual hikers.
The Italian side is reached from the Val Ferret above Courmayeur, with classic approaches starting near Planpincieux and mountain huts in the upper valley. The area offers outstanding views of glaciers, granite walls, and the surrounding high Alps, making it a landmark of alpine mountaineering.
Routes on Les Grandes Jorasses vary from demanding glacier approaches to highly technical climbs on mixed rock and ice. Weather, snow conditions, and crevasse hazards can change quickly, so the mountain requires solid experience, proper equipment, and careful planning. It is one of the most respected summits in the region.

There are no true trekking routes to the summit of Les Grandes Jorasses, but several scenic alpine walks in Val Ferret provide excellent views of the mountain. The most popular is the trail from Courmayeur to Planpincieux and onward toward Rifugio Bonatti. It is a well-marked mountain path with forest sections, open meadows, and wide panoramas of the glacier basin.
Another classic option is the approach from Arnouva toward the upper valley huts. These routes are moderate in difficulty, suitable for fit hikers in summer, and are mainly used to admire the north side of the massif rather than to reach the summit. Expect long walking times, changing weather, and alpine terrain.
The most famous line on Les Grandes Jorasses is the Walker Spur on the north face, a legendary mixed route with steep rock, ice, and sustained exposure. It is a serious objective for expert alpinists and demands excellent conditions, strong route-finding, and efficient movement on difficult terrain. The climb is long, committing, and highly weather dependent.
Other notable routes include the Croz Spur and the Hirondelles Ridge, both requiring advanced alpine skills. On the Italian side, approaches often cross glaciers and snow slopes before reaching technical sections. These climbs are not recommended without prior high-altitude experience, rope work, and crevasse rescue knowledge.
The nearest major populated area is Courmayeur, a well-known resort town in the Aosta Valley. Most Italian approaches begin in Val Ferret, commonly from Planpincieux or Arnouva. From there, climbers and hikers continue on foot toward mountain huts such as Rifugio Bonatti or higher glacier access points.
To reach the area, travel by car or bus to Courmayeur from Aosta or via the Mont Blanc Tunnel from France. In summer, local shuttle services may operate in the valley. Parking is available near trailheads, but access can be limited during peak season and in bad weather.
For guided ascents, the most reliable option is the Courmayeur Alpine Guides office, which offers certified mountain guides for technical climbs and glacier travel. Prices vary by route, group size, and duration, but a private guide for a demanding ascent in the Mont Blanc Massif often starts around EUR 450 to EUR 700 per day, excluding hut fees and equipment rental.
Other well-known providers in the area include UIAGM-certified independent guides and local alpine schools in Courmayeur. For a full expedition-style climb, total costs can exceed EUR 1,000 per person when guide fees, hut accommodation, and logistics are included. Always confirm current rates directly with the guide office before booking.
The best season for climbing Les Grandes Jorasses is usually from late June to September, when snow conditions are more stable and mountain huts are open. July and August offer the most reliable access, but they can also bring crowded huts and afternoon thunderstorms. Early season may still have winter snow on the upper mountain.
For technical routes like the Walker Spur, many climbers prefer a short weather window with firm overnight freeze and dry rock. Spring and autumn are generally less suitable because of avalanche risk, unstable snow, and colder temperatures. Conditions can change quickly, so a flexible schedule is important.
Climbing Les Grandes Jorasses requires full alpine gear: helmet, harness, rope, crampons, ice axe, glacier travel kit, and protection for mixed terrain. For technical routes, bring rock protection, ice screws, slings, carabiners, and belay devices. Warm layered clothing, waterproof shell, gloves, goggles, and a headlamp are essential.
Hikers on the lower valley trails need sturdy boots, weatherproof clothing, water, sun protection, and a map or GPS. Because the mountain environment is remote and exposed, emergency gear such as a first-aid kit, bivouac layer, and charged phone or satellite device is strongly recommended for all serious alpine outings.
Check the weather forecast and glacier conditions before setting out, and start early to avoid afternoon storms. In Val Ferret, trail access and parking can be busy in summer, so arrive early or use local transport. Mountain huts should be booked in advance during peak season, especially for multi-day climbs.
Do not underestimate the altitude and the length of the approaches. Even the scenic hiking routes involve significant elevation gain and changing terrain. For summit attempts, hire a certified guide if you lack advanced alpine experience. Mobile coverage is patchy in the upper valley and often unreliable on the mountain.
Les Grandes Jorasses is one of the iconic peaks of the Mont Blanc Massif and has long been a symbol of difficult alpine climbing. Its north face is among the most famous in Europe, attracting elite mountaineers for more than a century. The mountain has several summits, with the highest point on the Point Walker ridge.
The peak is also notable for its dramatic glacial setting above Val Ferret. From the Italian side, the mountain appears as a massive wall of rock and ice, especially at sunrise. It is a classic subject for alpine photography and a benchmark for high-level mountaineering skill.
How long does it take to climb Les Grandes Jorasses? A summit climb usually takes 1 to 3 days depending on the route, conditions, and whether you use a hut approach. Technical north-face routes often require an overnight stay or a very early start.
How long does it take to approach Les Grandes Jorasses? From the Italian side, the approach from Courmayeur to upper valley huts can take 2 to 5 hours on foot, while glacier access for climbing objectives may take longer.
Is there cell service and internet on the Les Grandes Jorasses? Coverage is limited and unreliable in the upper valley and on the mountain. Some signal may be available near Courmayeur and lower trailheads, but do not depend on it.
How difficult is it to climb Les Grandes Jorasses? It is a very difficult alpine peak. Most summit routes require advanced mountaineering skills, glacier travel experience, and comfort on steep mixed terrain.
Can beginners hike Les Grandes Jorasses? Beginners should not attempt the summit routes. However, they can enjoy lower-level hikes in Val Ferret with good views of the mountain.
How many people climb Les Grandes Jorasses? Numbers vary by season and route, but far fewer climbers attempt it than easier Alpine peaks. The most technical routes attract a relatively small number of experienced alpinists each year.
