Tour du Mont Blanc - Itinéraire principal

The Tour du Mont Blanc is a 170-km loop trail circling the Mont Blanc massif across France, Italy and Switzerland, gaining roughly 10,000 m of cumulative elevation over 7 to 11 days. Rated challenging, it is one of Europe's most famous long-distance treks, crossing high passes and eight valleys with constant views of the continent's highest peak.

About the Tour du Mont Blanc - Itinéraire principal

The Tour du Mont Blanc (TMB) is the classic circular route around the Mont Blanc massif, the highest mountain in Western Europe at 4,808 m. Following waymarked Grande Randonnée paths, the main itinerary covers approximately 170 km and accumulates around 10,000 m of vertical ascent — and the same descent — as it threads through three countries: France, Italy and Switzerland. As a designated Regional Walking Network (RWN) route of significant standing, it forms a complete loop, meaning you finish exactly where you began.

The trail was first established as an official GR route in 1951, though shepherds, smugglers and early alpinists had used these valley-to-valley passes for centuries before. Today it is one of the most walked long-distance trails on the continent, drawing tens of thousands of hikers each summer. Most walkers travel anticlockwise, starting and finishing at Les Houches in the Chamonix valley, but the circular nature means you can begin at any of the major access points, including Les Contamines-Montjoie, Courmayeur in Italy or Champex-Lac in Switzerland.

What makes the TMB exceptional is the variety packed into a single circuit. You cross from the glaciated French Pays du Mont-Blanc into the dramatic, sun-baked Italian Val Veny and Val Ferret, then over the Grand Col Ferret into the gentler pastoral landscapes of the Swiss Val Ferret, before returning to France via the Col de Balme. Each day delivers a high mountain pass, a new valley and a change of language, cuisine and culture. The highest point on the standard route is the Col des Fours at 2,665 m, with the Fenêtre d'Arpette (also 2,665 m) offering an equally high but tougher Swiss variant.

Route Overview & Stages

The main itinerary is typically broken into nine to eleven stages, depending on fitness, refuge availability and how many high variants you take. The table below shows a popular nine-stage anticlockwise schedule starting from Les Houches. Distances and elevation gains are approximate and vary slightly with the exact accommodation chosen each night.

Hikers who want shorter days commonly split the route into ten or eleven stages, adding overnights at Refuge des Mottets, Rifugio Bonatti or Tré-le-Champ. Whichever schedule you choose, logging each stage's distance and ascent in a tool like the HikeLoad route planner keeps your daily effort realistic.

Highlights & Points of Interest

• Col de la Seigne (2,516 m) — the dramatic high-pass border between France and Italy, with a sweeping panorama down into Val Veny and the south face of Mont Blanc.

• Chamonix-Mont-Blanc — the historic French alpinism capital and birthplace of mountaineering, easily reached for the start or finish.

Best Time to Hike the Tour du Mont Blanc - Itinéraire principal

The TMB season runs from late June to mid-September, dictated by snow on the high passes and refuge opening dates. In early summer, the Col des Fours and Fenêtre d'Arpette often hold steep snowfields into early July, which can force lower variants if you lack an ice axe and traction. By contrast, late September brings the risk of the first autumn storms and many refuges closing for the season.

The single best month to hike the Tour du Mont Blanc is July. By then the high passes are usually clear of snow, wildflowers carpet the alpine meadows, daylight is at its longest, and every refuge is fully staffed. Expect daytime valley temperatures of 18–25°C and cool nights near freezing at the highest huts. The trade-off is crowds: July is peak season, so refuges must be booked months ahead.

If you prefer quieter trails, early September is an excellent alternative, with stable weather, fewer walkers and golden larch colour beginning in the Swiss valleys — though check that your chosen refuges are still open. As of 2026, the Espace Mont-Blanc authorities and refuge operators continue to recommend reserving accommodation as early as January for July departures, as demand routinely exceeds bed capacity on the most popular stages.

Practical Information

Accommodation

The TMB is a true hut-to-hut trek. Mountain refuges (refuges in France, rifugi in Italy, cabanes in Switzerland) line the route roughly a day's walk apart. A bed in a shared dormitory typically costs €25–€45 per person, while half-board — dinner, bed and breakfast — runs €55–€90 depending on the country and altitude; Swiss huts are generally the most expensive. Many hikers prefer half-board because carrying multiple days of food is heavy and valley resupply points are limited.

Camping is possible but tightly regulated. Wild camping is largely prohibited within the protected zones, though bivouacking above the treeline between dusk and dawn is tolerated in some areas. Designated campsites exist near Les Houches, Les Contamines, Courmayeur and La Fouly, charging roughly €10–€18 per night. Booking dormitory beds well in advance is essential in July and August; a reliable hiking calorie and weight plan via the HikeLoad food planner helps you decide how much to carry between huts.

Getting There & Back

The standard start point, Les Houches, sits in the Chamonix valley in France. The nearest major airport is Geneva (GVA), roughly 1 to 1.5 hours away by road; frequent shuttle services and buses connect the airport directly to Chamonix and Les Houches. By rail, the Mont-Blanc Express line links Saint-Gervais-le-Fayet to Chamonix and Les Houches, connecting onward to the French TGV network at Saint-Gervais. From Italy, Courmayeur is reached via the Mont Blanc tunnel or bus from Aosta; from Switzerland, Champex-Lac connects by postbus to Orsières and the Swiss rail network at Martigny.

Permits & Fees

No permit is required to walk the Tour du Mont Blanc — the trail is freely open to all hikers. There are no entry gates or trail fees. Your main costs are accommodation, meals and the occasional cable car or bus if you shortcut a stage. Cross-border travel between France, Italy and Switzerland needs no special documentation for the trail itself, but carry your passport or ID card, as Switzerland is outside the EU customs union. Full route and refuge information is published by the regional tourism authority at Autour du Mont-Blanc, and high-mountain safety and weather guidance is available through the Météo-France mountain bulletin.

Gear & Packing List

Because the TMB is a refuge-based trek, you can travel surprisingly light — most walkers carry 7–9 kg with half-board bookings. A 35–55 litre pack is the sweet spot: large enough for layers, a sleeping bag liner (required in most refuges) and a day's food, without tempting you to overpack. Comfortable mid-cut boots or sturdy trail shoes are essential for the rocky descents off the passes, and trekking poles save your knees on the long drops into each valley.

For a comfortable hut-to-hut load, the Abisko Hike 35 is a great mid-size option, while ultralight hikers carrying a tent for the campsites often choose the 2400 Windrider or the larger 3400 Windrider. Whatever pack you pick, weigh every item — our roundup of the best ultralight backpacks of 2026 walks through how the leading models compare on weight and carry comfort.

Alpine weather changes fast, so pack a waterproof shell, an insulating midlayer, sun protection and a warm hat even in midsummer. Track your pack weight and load distribution in the HikeLoad gear database before you leave so nothing surprises you on the first 1,400 m climb.

Frequently Asked Questions

When is the best time to hike the Tour du Mont Blanc?
July is the best month, when the high passes such as the Col des Fours are clear of snow, all refuges are open and daylight is at its longest. Early September is a quieter alternative with stable weather, though some huts begin closing. Avoid June and late September, when snow or autumn storms can block the highest sections of the route.

How difficult is the Tour du Mont Blanc?
The TMB is rated challenging. The hiking itself is non-technical — no ropes or climbing — but you face roughly 10,000 m of cumulative ascent over 170 km, with a major mountain pass nearly every day. Good cardiovascular fitness, comfort on steep rocky descents and several training hikes beforehand make the daily 800–1,400 m climbs far more manageable.

How many kilometres per day will I walk?
On the standard nine-stage schedule you cover around 13 to 21 km per day, averaging about 19 km, with five to eight hours of walking depending on the pass crossed. Splitting the route into ten or eleven stages reduces daily distance to a gentler 10–15 km, which suits hikers carrying heavier packs or wanting time to enjoy the views and villages.

What accommodation is available on the trail?
The TMB is walked hut-to-hut, sleeping in mountain refuges spaced about a day apart. A dorm bed costs €25–€45, while half-board with dinner and breakfast runs €55–€90, with Swiss huts being priciest. Designated campsites near the main villages charge €10–€18. Book refuges months ahead for July and August, as beds sell out quickly on popular stages.

Do I need a permit to hike the Tour du Mont Blanc?
No permit or trail fee is required — the route is freely open across France, Italy and Switzerland. You only pay for accommodation, meals and any optional cable cars or buses. Carry a passport or national ID card, since Switzerland sits outside the EU customs union, but there are no checkpoints or paperwork specific to walking the trail itself.
