Four ways to approach Mont Blanc
Climbing Mont Blanc, hiking around it or running around the massif are four distinct projects, each with its own gear, its own calendar and its own level of demand. The summit at 4,805.59 m requires crampons, an ice axe and roped travel; the Tour du Mont Blanc (170 km) is a hike with no technical gear; the Marathon du Mont-Blanc and the UTMB are two separate races, organized by different bodies at two different times of year.
Summiting — mountaineering
Reaching 4,805.59 m via the Goûter route, Trois Monts, Gonella or Grands Mulets. A mountaineering route graded PD− to AD, crampons and ice axe mandatory, 2 to 3 days with a night at a high-altitude refuge.
The Tour du Mont Blanc — hiking
170 km and 10,000 m of cumulative elevation gain around the massif, crossing France, Italy and Switzerland, over 7 to 11 days. No technical gear: the TMB circles the massif without ever reaching the summit.
The Marathon du Mont-Blanc — trail running
Held in late June in Chamonix, 8 races from the Mini-Cross to the 90 km, organized by the Chamonix Sports Club. Entry by lottery for the longer formats, no UTMB Index required.
The UTMB — ultra-trail
Held in late August, 8 races from 15 to 300 km around the massif. Mandatory qualification: a UTMB Index in the right category and at least one Running Stone earned within the last 24 months.

Frequently asked questions
What everyone wonders before setting out
What is the real difficulty of Mont Blanc ascent?
Mont Blanc ascent is rated AD (Fairly Difficult) on the normal Goûter route. It requires excellent physical fitness, experience on glaciated terrain and altitude acclimatization. This is not a hike: it is a high-altitude mountaineering route.
What is the price of a Mont Blanc ascent with a guide?
In group format (2 days, 1 guide for 2 clients), the guide service alone is around €800–950 per person. All-inclusive packages including refuges and mountain railways (e.g., Chamonix Guides Company) start around €2,580/person. Add: refuges (~€143/night at Goûter), TMB (€40). Indicative total budget: €1,150–2,700.
Is Mont Blanc ascent accessible to a beginner?
Not without preparation. Mont Blanc ascent requires prior experience on glaciated terrain (crampons, ice axe), high physical fitness and ideally one or two 4,000 m peaks beforehand. For a motivated beginner: allow 9 to 12 months of training, use a certified UIAGM guide and first climb Grand Paradis (4,061 m) or Breithorn (4,164 m).
How long does it take to climb Mont Blanc?
Two full days minimum on the Goûter route: Day 1 ascent to Goûter refuge (3,835 m), Day 2 summit and descent. Some add an extra night at Tête Rousse for acclimatization.
Do you need a guide for Mont Blanc?
No, there is no mandatory permit or guide requirement in France. But for anyone without confirmed glaciated terrain experience, using a certified UIAGM mountain guide is strongly recommended. Between 15,000 and 20,000 attempts are recorded each summer according to the Compagnie des Guides de Chamonix, with a success rate of 40 to 65% depending on weather and support.
What is the difference between climbing Mont Blanc, the Tour du Mont Blanc and the UTMB?
Three distinct projects. The climb reaches the summit at 4,805.59 m: this is mountaineering, with crampons, ice axe and roped travel, over 2 to 3 days. The Tour du Mont Blanc (TMB) is a 170 km hike that circles the massif in 7 to 11 days, without ever reaching the summit and without technical gear. The UTMB is a timed foot race held in late August, with mandatory qualification.
Are the Marathon du Mont-Blanc and the UTMB the same race?
No. The Marathon du Mont-Blanc takes place in late June, organized by the Chamonix Sports Club, and requires no UTMB Index. The UTMB is run in late August under a different organization and requires a valid UTMB Index plus a Running Stone. Only the Marathon's 90 km race is listed as a UTMB Index qualifying race.
