Alternative Track if you are staying in Courmayeur for 2 nights: After a climb out of Courmayeur, the path remains flat, walking high on the slopes of Val Ferret with a dramatic panorama of ice and rock on your left. Continue to Rifugio Bonatti before descending to the Bivio Rifugio Bonatti

The climb from Courmayeur zig-zags through pine forest which offers shade but also obstructs the views. It is only as you burst above the tree-line near Rifugio Bertone that you suddenly get a view to Courmayeur and realise how much height you have gained. Moments later, you round a corner onto the upper slopes of Val Ferret and have a stunning vista throughout the entire valley. Sweeping your gaze left you can see Col de la Seigne at the head of Val Veni; you crossed this pass several days ago, and just beyond lies France. Turning right, you can see all the way to Grand Col Ferret marking the border with Switzerland and which you must cross tomorrow. Spanning the distance between these two cols is a panorama of jagged rock and ice that makes up the Mont Blanc massif.

As you walk along the valley, parallel to the Mont Blanc massif the mountains shift slowly beside you which only reinforces how giant they are, however by the end of the day it will be the angular, imposing figure of the Grandes Jorasses that takes centre stage rather than Mont Blanc. Rifugio Bonatti perhaps offers the best possible views to Grandes Jorasses and is perfectly situated to catch those gorgeous sunrise colours hitting the mountain in the morning.

You can shorten today’s walk by taking the bus on the Val Ferret line to Bivio Rifugio Bonatti, which only leaves 400 metres of ascent (perhaps 1-1½ hours) to reach the refuge.

One of the many charms that ensures Rifugio Bonatti is consistently a highlight of the Tour du Mont Blanc is its remoteness and the absence of any road to get there. This means there is no baggage transfer to Rifugio Bonatti, so take only your overnight things with you, and you will be reunited with your full luggage the following night.

Safety information

There are several river crossings. There are always stepping-stones available but these may be slippery, and especially when wet. Take extra caution on these crossings.

Some of the path is along rocky steps; be careful as these may be slippery, especially when wet.

There are some exposed edges; be sure to read instructions carefully, stick to the main path, and don’t wander close to the edge. Use handrails where provided.

In early spring/summer there may still be patches of snow. Walk around where it is possible, and otherwise place your feet carefully and use walking poles if you have them.

This route is above 2,000 metres so bear in mind you may feel a shortness of breath and additional muscle fatigue associated with the altitude.

Tips and hints

Rifugio Bonatti

Walter Bonatti was an Italian climber who relished the challenge of climbing little-known and technically challenging mountains. He achieved several ‘first ascents’ including the Gasherbrum IV (the world’s 17th highest mountain), and pioneered many new routes up already climbed mountains. He was a mountain guide in Courmayeur and has a hut in Val Ferret dedicated to him. Be sure to pop inside to see some of his photos and equipment. 

Duke of Abruzzi Alpine Museum

This museum was started by the Duke of Abruzzi, a titan of the mountaineering world during the early 20th century. The museum houses a wealth of documents, photos, climbing equipment and souvenirs which allow you to uncover 150 years of mountaineering history. The museum is in the Società delle Guide building in Courmayeur.

Bivio Rifugio Bonatti Bus Stop

Turn-by-turn directions

Start in the square in front of the Church of San Pantaleone in Courmayeur and bear uphill between the church and Societá des Guides. Walk along the road until a ‘Stop’ junction after 300 metres, where you bear right to continue uphill passing through the hamlet of Villair. Villair is a peaceful commune of Courmayeur characterised by alpine houses and sleepy, narrow streets.

This road will eventually become unpaved, crossing a bridge over a river at 1.7km. After 100 metres turn right sharply to leave the road and follow a rocky path uphill through the forest, following the TMB sign with yellow arrows. At 2.1km, bear right onto the gravel road, then after 20 metres turn left sharply onto a footpath, following the sign to Rifugio Bertone. This footpath will zig-zag steeply uphill through the trees.

At 4.3km you will burst above the trees to discover Rifugio Bertone. From here you can enjoy a final view to Courmayeur, and also the last opportunity to get some food or drink before Rifugio Bonatti.

At 4.5km, bear left as the path forks to pass under the avalanche barriers and to follow the sign to Rifugio Bonatti and Val Ferret. This path will remain mostly flat, walking high on the slopes of the valley with outstanding views on your left. At 6.3km ignore the left turn downhill as the path forks near some derelict huts and continue straight following the sign for TMB. As you reach the derelict hut of A. Leché at 8.5km, you must bear right to pass above it.

At 9.8km the path continues over a wooden bridge and passes the derelict alpine huts of Arminaz Desot. The path continues along the upper valley flanks, ignoring vague paths heading downhill on your left and uphill on your right.

As the path forks at 11.5 km, bear right to take the worn path that zig-zags uphill. There is no signpost here but after a few minutes, you will see the welcoming structure of Rifugio Bonatti. Does any terrace in the world boast a better view? Why not enjoy a celebratory drink here?

One of the many charms that ensure Rifugio Bonatti is consistently a highlight of the Tour du Mont Blanc is its remoteness and the absence of any road to get there. 

Finish your days walk by descending from Rifugio Bonatti to the bus stop (Bivio Rifugio Bonatti, 400m of descent) and taking the bus on the Val Ferret line back to Courmayeur.
