Do you need to book the Tour du Mont Blanc? What happens without a booking

For a refuge bed in July or August: yes, book. The official TMB site calls booking strongly recommended, even essential in high season, and two days after summer 2027 opened, the Refuge des Mottets already showed 21 of its 31 July nights as full. Without a booking you are left with a tent and the few campsites that take walkers as they come, under bivouac rules that change by commune and by country. And the French communes on the route plan to require a booking for every night from spring 2027.

What the official site says

The platform of the TMB refuge wardens’ association, montourdumontblanc.com, answers the question in its FAQ: booking is strongly recommended, even essential in high season. Its home page adds that in high season the refuges and other places are often full several months ahead. Its booking guide says that between mid-July and mid-August you really have to book early, and that June and September can be more flexible.

The same guide notes that cancellations do happen, especially several weeks before a date, so a refuge that shows full today is worth checking again later.

What happens if you turn up without a booking

No page we read says what a refuge does when a walker arrives unbooked on a full night, and none promises a bed. What the sources do say:

Who takes the booking

Most beds are on one platform. A few classic nights are not.

Every night in order, with the places in each village: the TMB huts in order.

Book in the right order

The TMB 2027 booking plan tells you which bed opens when and in which order to book, so the scarce nights come first: every night of the classic eleven-day tour, how it books, a fallback in the same valley, and a calendar file that reminds you on the right days. PDF in English, Dutch and French, €29 once. It books nothing and holds no beds.

2027: a booking for every night on the French side

On 16 September 2026 the seven French communes on the route, Vallorcine, Chamonix, Les Houches, Saint-Gervais, Les Contamines-Montjoie, Beaufort and Bourg-Saint-Maurice, unanimously approved the principles of a charter with the refuge wardens, campsites, guides, transport companies and the State:

The aim is to have it working in spring 2027. It is not a rule yet: the final text was due in mid-October 2026, and the communes expect to sign before the end of 2026. It is a French charter: every commune in the press release is on the French side of the tour.

Booking in time, from today

  1. On the platform, now. Book the night with the fewest options first, as the platform itself advises. On the classic stages that is the night around the closed Croix du Bonhomme: Nant Borrant, La Balme, Les Chapieux or Les Mottets.
  2. By email, now: Rifugio Elisabetta, which has published no 2027 date.
  3. Keep checking Bonatti’s form, which on 19 October 2026 took only its winter season.
  4. In January: La Flégère on 5 January 2027 at 00:01, the Chalet des Contamines during the month.
  5. Before you pay: the platform refunds 80% of the deposit if you cancel more than 30 days ahead, and nothing within 30 days unless you took its insurance.
  6. Hold one fallback for a night that is not confirmed yet, and let it go the day the real booking comes through.
