What Is the Tour du Mont Blanc?
The Tour du Mont Blanc (TMB) is a 170-kilometre trek that circumnavigates the Mont Blanc massif, passing through France, Italy, and Switzerland. It's one of the most popular long-distance hikes in the world — and for good reason. The scenery is extraordinary, the infrastructure is excellent, and the cultural variety of crossing three countries on foot is unmatched.
When Should You Go?
The TMB season runs from mid-June to mid-September. Each window has trade-offs:
- Mid-June to early July: Snow patches on high cols, fewer crowds, wildflowers in bloom. Some refuges may not yet be open.
- July to mid-August: Peak season. All refuges open, trails fully clear, but expect crowds and full huts. Book 3-6 months ahead.
- Late August to mid-September: Thinning crowds, cooler temps, autumn colours starting. Some refuges begin closing after September 10.
The sweet spot for most hikers is late June or early September.
Do You Need a Permit?
No permit is required for the TMB itself. However, wild camping is restricted in many areas (especially in France and Switzerland). You can bivouac (set up camp after 7pm, break down by 7am) in most places, but designated campsites are the safest bet.
How Fit Do You Need to Be?
The TMB involves roughly 10,000 metres of cumulative elevation gain over 7-12 days. That's the equivalent of climbing from sea level to the summit of Everest — and back down — over the course of a week.
You don't need to be an athlete, but you should be comfortable hiking 15-20km per day with a loaded pack on hilly terrain. An 8-week training plan focusing on uphill walking with a weighted pack is enough for most people.
What Does It Cost?
Budget €80-150 per day depending on your accommodation style:
- Refuges (dorm): €50-80/night including half-board (dinner + breakfast)
- Hotels/gîtes (private room): €80-150/night
- Camping: €10-20/night plus food costs
Total budget for 10 days: €800-1,500 for accommodation and food, plus travel to/from the trailhead.
The One Mistake That Ruins Most Treks
Not booking refuges early enough. Popular huts like Refuge Les Mottets, Rifugio Bonatti, and Refuge de la Croix du Bonhomme fill up months in advance. If you're hiking in July or August, start booking in March. September hikers should book by June at the latest.

Clockwise or Anti-Clockwise?
The traditional direction is anti-clockwise, starting from Les Houches or Chamonix. This puts the sun at your back in the morning and saves some of the most dramatic scenery (the Italian side) for the middle of your trek.
Going clockwise is equally valid and has the advantage of fewer crowds on some stages, since most guided groups go anti-clockwise.
Getting There
Most hikers fly into Geneva (GVA), then take a bus or shuttle to Chamonix. The journey takes about 90 minutes and costs €20-40 depending on the service.
Final Advice
Start planning early, train consistently, pack light, and don't over-schedule. The TMB is meant to be enjoyed, not endured. Build in at least one rest day, and leave room for the unexpected — a spontaneous dip in Lac de Combal, a long lunch in Courmayeur, or an extra hour at a viewpoint because the light is perfect.
