La Jonction: One of the Chamonix Mega-Classics
Out and backs aren't always ideal, but in this case, you get twice the viewing time
Θ Out & Back
La Jonction is one of the Chamonix runs you send people to if they have limited time in the valley, want heaps of vertical, and hope to see the big mountains up close. As mountain runners, often times our goals are summits, but with La Jonction, the goal is the end of the trail, the edge of the glaciers. You are still far below the summit, feeling tiny, and standing in awe at the ice flowing from high on Mont Blanc.
La Jonction is also a huge amount of vertical in a short distance that is commonly done as an out and back. The trail starts at 1000 meters in Les Bossons, and meets its end 8km higher, 1600 meters above at La Jonction. There, you’ll give your legs a rest on a rocky island splitting the massively wide glacier sweeping down Mont Blanc into the Glacier de Taconnaz and Glacier des Bossons.
You’ll start this tour with some time switching back and forth in the forest before trees thin to bushes and you start to get glimpses of what you are surrounded by, which is mostly ice.
Finally, you reach the alpine world where just below the top you scramble up some rock and pull on a few cables before the last bit of talus to the flat finish. The last bit of dry ground is flat where rock meets ice, gaping crevasses and some seracs.
Take a dry shirt, something warm to slip on, and a snack to enjoy as you sit stunned by the landscape.

There is a small hut about half way up the route, the Chalet des Pyramides, where you can typically get food and drinks.
Have extra food & drink for a good long sit at La Jonction.
- While it is a great trail, this route really is all about what you'll see, save it for the right conditions.
