This glacier expedition in the Tré-la-Tête massif explores an authentic high-mountain environment, away from the main routes of the Mont Blanc massif. Over five days, the itinerary links several iconic huts and traverses varied terrain: glaciers, rocky sections, long snow ridges, and panoramic summit ascents.
The ascent of Mont Tondu, followed by the Dôme des Glaciers, offers a gradual immersion into a magnificent glacial environment. The final day, devoted to the traverse of the Dômes de Miage, is a highlight: an elegant, airy, and fluid line, with views of the Mont Blanc massif.
Led by a mountain guide, this trip highlights the coherence of the Tré-la-Tête area: a wild, technical yet accessible space, ideal for continuous progression in glacier mountaineering. A rich, balanced, and deeply aesthetic itinerary.
For groups: every Sunday from mid-June to mid-September, depending on mountain conditions.
For private bookings: daily from mid-June to mid-September, depending on mountain conditions and hut availability.

One guide for 4 participants for the first 4 days, then 1 guide for 2 participants for the Dômes de Miage. For groups: departure with 4 participants.
Basic mountaineering experience is required (crampon use, roped walking). Good physical preparation is necessary for this expedition, which is aimed at fit individuals. You will be walking between 6 and 10 hours per day, so you should prepare by doing long-duration cardiovascular activities.
Endurance sports: cycling, running, and hiking. Remember that for 5 days you will be carrying an 8 kg backpack, which significantly increases the effort required, so train with this extra weight during your outings.
You will be traveling on an unmarked high-mountain route and must be aware of the hazards associated with this activity (crevasses, serac falls, rockfall, avalanches, very low temperatures).
We are available to answer any questions you may have.

Repatriation

Cancellation
We also offer optional “cancellation” insurance at a rate of €12/day. This insurance does not take into account the sporting nature of our trips. It must be purchased at the time of registration to take effect.
As a reminder, cancellation insurance covers you from the moment you register until the start of your trip if something happens and you cannot attend. We apply cancellation fees as specified on our registration form and in our terms of sale. These fees may be reimbursed by the cancellation insurance if your reason for cancelling is covered.
If you pay by credit card, feel free to check the insurance included with it.
As a reminder, in the event of cancellation you must file your claim with the insurer within 5 days of the accident or reason for cancelling, otherwise it will not be valid (then check whether the reason for cancellation is covered).
