A guided ridge day sits between hiking and technical alpine climbing: a long line of granite, short approaches, and a guide moving you along it efficiently. The climbing is rarely hard — most of these traverses sit around grade III with short steps of IV — but the exposure is continuous, and comfort on a narrow crest in mountaineering boots matters far more than your climbing grade.
Here are some of our most popular ridges:
Frêtes des Charmoz. Reached from the Montenvers railway, this is the longest and most forgiving of the classics — a broad crest with easy scrambling and only short sections of real climbing. It looks straight across at the Drus and down onto the Mer de Glace, which is arguably the best view from any ridge in the valley. Often the first one a guide suggests if you have not done this kind of day before.
Aiguilles Crochues Traverse. From the Flégère lift, an hour's approach leads to a traverse of two summits on excellent Aiguilles Rouges granite. It is a step up from the Charmoz in sustained difficulty and exposure without becoming serious, and the descent drops off the back on a good trail. Probably the most-climbed ridge on this side of the valley.
Perrons Traverse. On the border of France and Switzerland, above Vallorcine, reached by road toward Emosson. The approach is an hour and a half, and the day is the longest of the three, with beautiful views on the blue water of the Emosson dam as well as the Mont Blanc massif.
Beyond these, guides run the Chapelle de la Glière from Flégère, and across the tunnel the Aiguilles Marbrées and the Aiguille d'Entrèves traverses from the Skyway — higher, glaciated approaches at around 3,500 m.
Ratio is one to two on almost all of these routes, and several guides charge per rope team rather than per person — so a pair typically pays around half each. Most parties are back at the lift by mid-afternoon.
