Alps — Mont Blanc, Chamonix, Aiguilles Rouges and Val Ferret

Regional overview

This region is one of the densest high-alpine hiking areas in Europe: the north side of the Mont Blanc massif above Chamonix, the Aiguilles Rouges balcony opposite Mont Blanc, the upper Chamonix valley around Le Tour and Vallorcine, and the Italian Val Ferret above Courmayeur.

The walking character is strongly shaped by cable cars, cog railways, glacier views, high balcony paths, and steep but non-technical mountain trails. The main hiking centres are Chamonix, Les Praz / La Flégère, Argentière, Le Tour, Vallorcine, Montenvers, Courmayeur and Val Ferret.

Many classic walks are lift-assisted, but they still cross serious mountain terrain. Snow, thunderstorms, exposure, lift timetables and sudden weather changes matter. For mid- and high-mountain outings, hikers should check current mountain conditions before departure.

The Aiguilles Rouges Nature Reserve has specific restrictions. Dogs and other pets are prohibited, camping and campfires are restricted, and walkers should remain on the main paths. Swimming is prohibited at Lac Blanc and the Lacs des Chéserys.

Selection rationale

These five hikes were selected to give a balanced picture of the region: Lac Blanc from La Flégère for the iconic Aiguilles Rouges lake-and-Mont-Blanc panorama; the Grand Balcon Nord for the classic Mont Blanc-side balcony traverse; the Aiguillette des Posettes for a compact summit and ridge viewpoint above Le Tour; Refuge Albert 1er from Col de Balme for a high-alpine glacier-view hut walk; and Lavachey – Rifugio Bonatti – Col Entre-deux-Sauts for the Italian Val Ferret side of the Mont Blanc massif.

Summary table

1. Lac Blanc from La Flégère

Snapshot

Itinerary

From the La Flégère upper station, the path descends into the Combe de la Chavanne, then climbs past the Chalets et Lac de la Flégère at 2,027 m. It continues below the Tête du Aubuy, skirts a ridge, joins the path coming from Argentière, and reaches Lac Blanc in a high rocky basin opposite the Mont Blanc massif. The Chéserys lakes make a possible descent variant, but the official 7 km statistics correspond to the Flégère–Lac Blanc return route.

Why it is essential

Lac Blanc is the emblematic Aiguilles Rouges viewpoint: a high mountain lake directly opposite Mont Blanc, the Aiguille Verte, the Drus and the Chamonix aiguilles. It is the most recognisable lake walk in the Chamonix valley.

Equipment

• Sturdy hiking boots
• Weatherproof layer
• Warm layer
• Water and food
• Map or GPS
• Sun protection
• Navigation backup
• Trekking poles recommended
• Microspikes or crampons may be needed if snow remains

Hazards and notes

High mountain weather exposure and early-season snow may remain on the upper path. Dogs are prohibited in the Aiguilles Rouges Nature Reserve, and swimming is prohibited at Lac Blanc and the Lacs des Chéserys. Current trail status should be checked before publication or departure.

2. Grand Balcon Nord: Plan de l’Aiguille to Montenvers

Snapshot

Itinerary

From the Plan de l’Aiguille cable-car station, the path drops towards the Refuge du Plan de l’Aiguille, then traverses across the slopes below the Blaitière and Nantillons glaciers. It continues across the Grépon torrent, reaches the fork below Signal Forbes, and follows the panoramic line rather than the steep shortcut through couloirs. The final section descends to Montenvers, with views changing from the Aiguilles de Chamonix to the Drus, Aiguille Verte, Grandes Jorasses and Mer de Glace.

Why it is essential

This is the classic Mont Blanc-side balcony walk. It gives close views of the Chamonix aiguilles and then a dramatic arrival above the Mer de Glace, linking two of the valley’s best-known mountain transport sites.

Equipment

• Sturdy hiking shoes or boots
• Weatherproof layer
• Warm layer
• Water and food
• Sun protection
• Map or GPS
• Plan for lift and train timetables
• Trekking poles useful for the descent

Hazards and notes

The steep shortcut to Montenvers crosses dangerous couloirs in snow; use the standard panoramic path when conditions are uncertain. Lift and railway schedules are essential. Avoid in thunderstorms, hard snow or poor visibility.

3. Aiguillette des Posettes from Le Tour

Snapshot

Itinerary

From Le Tour, the route climbs from near the bridge on the right bank of the Arve. It enters light forest, reaches the Pierre-Fendue junction at about 1,950 m, then climbs right past avalanche-protection structures and old slate quarries. The final section follows the ridge to the Aiguillette des Posettes, with views towards Mont Blanc, the Tour Glacier, Le Buet, Les Perrons, Vallorcine and the upper Chamonix valley.

Why it is essential

Aiguillette des Posettes is one of the most efficient summit walks in the Chamonix area: steep, compact and panoramic. It represents the Le Tour / Vallorcine end of the valley and gives a different angle on the Mont Blanc massif.

Equipment

• Sturdy hiking boots
• Weatherproof layer
• Warm layer
• Food and water
• Sun protection
• Map or GPS
• Trekking poles recommended

Hazards and notes

Steep climb with weather exposure on the ridge. Avoid the ridge in thunderstorms or strong wind. Early-season snow or wet grass can make the route more serious.

4. Refuge Albert 1er from Col de Balme

Snapshot

Itinerary

From the Autannes chairlift arrival area, the path heads right, passes near the outlet of Lac de Charamillon, and traverses the mountainside towards the Glacier du Tour. It rounds a spur, crosses a slope above a tricky ravine protected by ramps, then reaches the moraine below Refuge Albert 1er. The hut stands near the Glacier du Tour and is a starting point for higher alpine routes, but this day-hike stops at the refuge and avoids glacier travel.

Why it is essential

This is the most accessible non-glacial day hike in the selection for close views of the Glacier du Tour. It gives a high-alpine atmosphere without requiring ropework in normal summer conditions, provided the hiker remains on the marked path and does not continue onto glacier terrain.

Equipment

• Sturdy hiking boots
• Weatherproof layer
• Warm layer
• Hat and gloves outside stable midsummer weather
• Water and food
• Navigation backup
• Trekking poles
• Microspikes or crampons may be needed in early season if snow remains

Hazards and notes

The route includes a traverse above a ravine and moraine terrain near a glacier. Do not continue onto glacier terrain without proper alpine equipment and skills. Snow on the ravine section can make the route significantly more serious. Avoid in low visibility or unstable weather.

5. Lavachey – Rifugio Bonatti – Col Entre-deux-Sauts

Snapshot

Itinerary

From Courmayeur, the access road enters Val Ferret. The walking route begins beyond Lavachey, just before the Malatrà stream, where trail 42 leaves the road on the right. It climbs to Rifugio Bonatti, continues through the pastures of Malatrà Inferiore and Malatrà Superiore, ignores the left branch towards Col Malatrà, then crosses a broad upper basin before climbing to Pas / Col Entre-deux-Sauts at about 2,520 m.

Why it is essential

This route gives the Italian counterpart to the Chamonix-side classics: a Val Ferret balcony and pass route beneath the Grandes Jorasses side of the Mont Blanc massif, with Rifugio Bonatti as a key landmark on the Tour du Mont Blanc and Alta Via context.

Equipment

• Sturdy hiking boots
• Weatherproof layer
• Warm layer
• Food and water
• Sun protection
• Map or GPS
• Trekking poles recommended

Hazards and notes

Lingering snow possible in early summer and rapid weather changes in the upper basin. Follow route 42 carefully where it divides from the Col Malatrà branch. Confirm hut services and Val Ferret transport before departure.

• The GPX and KML links included here are source-route links. They will later be replaced with newly created route files.
• The Lac Blanc official Chamonix page showed a temporary closure during the source check. Current trail status should be rechecked before publication.
• For the Val Ferret hike, the official page gives outward distance and time only. The return distance is derived by doubling the official one-way length.
• Lift schedules, Montenvers railway operation and Val Ferret shuttle timetables are seasonal and should be checked again close to publication.
• Snow conditions can materially change the seriousness of all five hikes, especially early in the season.
