Tour du Mont Blanc: Route, Stages, Distance and When to Go

Where the Tour du Mont Blanc runs and who it suits

The circuit runs counter-clockwise around the massif through France, Italy and Switzerland, with roughly 170 km (105 mi) of trail and about 10,000 m (32,800 ft) of total ascent on the classic line. It starts and finishes at Les Houches or Chamonix on the French side and passes through Courmayeur in the Aosta Valley. The official route organization frames it as three countries and one identity, with around 60 hours of walking spread over ten days, which matches the effort most hikers should budget for.

It suits hikers with multi-day mountain experience and a solid aerobic base more than climbers looking for technical ground. Most days gain or lose somewhere between 700 m and 1,400 m (2,300–4,600 ft), and sure footing matters more than scrambling ability. If you have done a week of hut-to-hut walking in the Alps before, you are the right audience; if not, plan a training block and consider a half-circuit first. For an overview of the wider massif and its other trails, the mont blanc hiking guide covers the surrounding valleys.

Start, finish and getting to the trailhead at Les Houches and Chamonix

Most hikers begin at Les Houches, a short valley bus ride from Chamonix, because the classic first climb to Col de Voza starts from the village. The circuit finishes either above Chamonix via the Lac Blanc balcony or back down at Les Houches, depending on your variant. Chamonix is the practical base: it has the largest choice of lodging, gear shops and transport links, and it is where you stage your pack the night before. If you want to add rest-day walks from that base, hiking in Chamonix covers the best day hikes and trailheads.

The standard approach is by air to Geneva, then a shared shuttle or bus transfer into the Chamonix valley; package operators list Geneva–Chamonix shared shuttles as a standard add-on. Book your arrival night in the valley rather than trying to reach a mountain hut the same day, because late transfers and afternoon weather do not mix well with a first climb.

There is a useful shortcut on the first day. From Les Houches you can take the cable car to the Bellevue plateau, which skips the initial 667 m (2,188 ft) climb to Col de Voza. It is a fair choice if you arrive late or want a gentler opening day, but you lose the conventional start and the continuity of a full self-powered circuit.

Distance, total ascent and typical duration

Plan on seven to eleven days for the full circuit, with a ten-day split as the common shape. The published figures put the classic route at about 170 km (105 mi) and roughly 10,000 m (32,800 ft) of ascent, which is a serious undertaking even though it requires no technical climbing. Fitness and perseverance matter more than technique.

One widely used ten-day itinerary averages around 16 km (10 mi) and 976 m of ascent per day, with the longest stage at 22.3 km (13.9 mi). Treat that as one valid breakdown rather than the only correct one: splitting the long French stages or adding a rest day in Courmayeur is a normal adaptation. If you want a day-by-day plan to compare against, a full tour du mont blanc itinerary sets out the splits and walking hours.

Direction of travel and main route variants

The standard direction is counter-clockwise from Les Houches or Chamonix, heading south into the Bionnassay valley. That sequencing puts the Italian flanks, Col Ferret and the Swiss valleys in the second half of the trek, when your legs and your mountain judgement have caught up with the route. Clockwise walking is less crowded on some sections, but it throws the steepest ascents at you from the harder side and many hikers find the descents tougher on the knees. Clockwise is also a practical fallback when hut availability in the western French sector is tight.

Two variants deserve to be treated as decisions, not defaults. Col des Fours extends beyond Col du Croix du Bonhomme to about 2,665 m (8,743 ft), the highest point on any standard variant, and is worth saving for a clear day. Fenêtre d'Arpette is a higher, more exposed crossing between Champex and Trient that needs stable weather and sure footing. The Lac Blanc balcony on the final day is the classic finish above the Chamonix valley and one of the most photographed viewpoints on the trail.

On the Swiss side, the path between Prayon and Branche in the Treutsebo sector has been rerouted because of rockfall risk, with the new line open and signposted from Saturday 11 July 2026; the old route is closed and must not be used. Camping and bivouacking are prohibited in that area, and the official page points hikers to the campsites at La Fouly, Les Rocailles and Relais d'Arpette instead. Check signage rather than a cached track when you reach that sector.

The classic stage-by-stage route: passes, valleys and landmarks

In the ten-stage breakdown, Day 1 runs from Chamonix or Les Houches to Auberge du Truc at 14.8 km (9.2 mi) and 1,410 m of ascent, taking five to seven hours over Col de Tricot. Day 2 is the longest at 22.3 km (13.9 mi) and 1,320 m of ascent, seven to nine hours. Both are honest fitness tests placed at the front of the trip, so keep the first days short on ambition and long on steady pacing.

Day 3 covers 14.3 km (8.9 mi) and 990 m of ascent to Rifugio Elisabetta, then Day 4 is a deliberate recovery day of 9.1 km (5.7 mi) with only about 90 m of ascent to Rifugio Monte Bianco. Use that short day to rest before the push toward Courmayeur. Day 5 climbs 1,060 m over 11.3 km to Rifugio Gio Bertone, one of the finest balcony positions above the Italian valley.

The second half opens with Day 6 to Gîte Alpage de La Peule at 20.7 km (12.9 mi) and 1,090 m of ascent, crossing into Switzerland over Col Ferret. Day 7 is a 22.3 km (13.9 mi) traverse with less climbing at 680 m, and Day 8 drops to Trient over 15.4 km (9.6 mi) and 730 m of ascent. Day 9 climbs 1,090 m to Gîte Le Moulin, and Day 10 returns to Chamonix over 17.9 km (11.1 mi) and 1,300 m of ascent via Col de la Balme and the Lac Blanc balcony.

The route is waymarked in all three countries with red-and-white paint flashes, so navigation is straightforward in clear weather. For paper coverage of the French sections, the IGN 1:25,000 sheets 3630OT for Chamonix and 3531ET for Beaufortain are the usual choice, with IGM and Swisstopo equivalents for Italy and Switzerland. Carry a map or offline track anyway; cloud can close the cols quickly and paint flashes disappear under snow.

Huts and accommodation on the circuit

There are more than 110 accommodation options along the circuit, from mountain refuges in France to rifugi in Italy and cabanes in Switzerland, plus valley hotels and gîtes. Dormitories typically hold eight to twenty beds and are the cheapest, most social norm; private rooms exist at some huts and most valley gîtes. Half-board is available almost everywhere and is the sensible default, since arriving to a hot dinner after a long stage saves both weight and time.

The huts that sell out first include Rifugio Elisabetta at the end of the Elisabetta stage, Rifugio Bonatti on the Courmayeur stretch, Gîte Alpage de La Peule after Col Ferret and anything in the Lac Blanc area. If a target hut is full, shift laterally into the valley: Les Contamines-Montjoie and Les Chapieux on the French side, Bourg Saint Maurice or La Thuile as substitutes near Elisabetta, La Fouly below Col Ferret, and Champex-Lac or Trient in Switzerland. A dedicated tour du mont blanc huts page helps you map the beds against each stage.

Booking huts and when the season opens

Popular huts for July and August begin accepting reservations between September and January of the preceding year, so aim to have your full itinerary locked in by February for peak-season dates. Late August and September leave more room, but the best-placed huts on key stages still fill quickly. If you would rather not manage a chain of reservations in three countries, a self guided booking handles the sequence for you.

Luggage transfer is not possible on most mountain stages because the paths are not vehicle-accessible, though it can work between some valley towns on specific stages. For everything else, pack for carrying your own kit and plan resupply in the valley stops.

Camping and bivouac rules along the route

Rules differ by country, so treat this section by section rather than as one blanket policy. In France, bivouacking above a certain altitude and outside protected areas is generally tolerated if you arrive late and leave early, while camping in the Contamines-Montjoie nature reserve is restricted. In Italy and Switzerland, wild camping in national parks and nature reserves is largely prohibited. Designated campsites exist in several valley towns including Les Contamines, Courmayeur, Champex-Lac and Trient.

In the Treutsebo sector between Prayon and Branche, camping and bivouacking are strictly prohibited, and the official page directs hikers to the campsites at La Fouly, Les Rocailles and Relais d'Arpette. The bivouac and wild camping section of the official route site sets out the regulations and good practice for each sector before you commit to a night out.

Best months to hike and what changes through the season

The main season runs from mid-June to mid-September. June still holds snow on the higher passes such as Col de Tricot, Col Ferret and Fenêtre d'Arpette, some huts run limited services, and morning trails can be icy, so it suits experienced alpinists rather than first-timers. July brings the full season with all huts open and trails snow-free, at the cost of afternoon thunderstorms and peak crowds on the popular stages.

Late August is the sweet spot for many hikers: crowds thin after the first week as French school holidays end, temperatures are comfortable and huts are fully operational. The exception is UTMB race week, typically the last weekend of August, when Chamonix and some huts become exceptionally busy. September offers beautiful light and far fewer people, with early snow possible on high passes from mid-September and some huts closing in the first two weeks of the month.

Exposure, snow on the passes and afternoon storms

The real hazards are exposure on the high cols, lingering snowfields early and late in the season, and afternoon storms that build fast in July and August. Col des Fours and Fenêtre d'Arpette raise the stakes, and both should be walked only in stable weather with sure footing. The practical response is to start early, aim to be at your hut by early afternoon, and turn back from an exposed variant rather than race a building storm.

Valley forecasts are unreliable at altitude, so read the weather for the hut you are heading to rather than for Chamonix or Courmayeur. Carry traction for early-season snowfields and know how to use it before you need it on a sloping traverse.

Short versions and half-circuits

The Italian and Swiss halves work as standalone treks when a full circuit does not fit your calendar. The western half from Chamonix to Courmayeur is a complete experience in its own right, and a five-day version averages about 13.6 km (8.5 mi) and 842 m of ascent per day. If you only have a week, choose the half that matches your transport rather than trying to compress the whole loop.

Guided and self-guided formats differ mainly in what is taken off your plate. Guided departures handle navigation, hut bookings and group logistics, while self-guided packages typically pre-book the accommodation chain and leave the walking to you. Both suit hikers who want the route solved in advance; independent hikers who enjoy the planning can book huts directly. A comparison of mont blanc hiking tours shows the formats side by side.

Package operators publish their own day counts and fitness ratings, from five-day comfort loops to eleven-day fully guided circuits. Ask what is included in the price quoted and whether luggage transfer applies on any stage, since it is not possible on most mountain sections.

Fitness, training and pack weight

Build an eight-to-twelve-week programme with four or five walking days a week and at least one back-to-back weekend of five hours on Saturday and three on Sunday. Stair climbing and loaded-pack walking transfer best to the relentless ascents, and you should train descents too, because your quads and knees take the real punishment. Maximum altitude on the classic route is around 2,665 m (8,743 ft), well below the threshold where altitude sickness becomes a concern for most people.

Keep pack weight down by taking half-board at the huts, which removes dinner and breakfast from your load, and by resupplying in valley towns rather than carrying ten days of food. A light shell, warm mid-layer and traction for early-season snow cover the conditions you are likely to meet.

Fees, permits and trail rules

Your costs are beds, meals, transfers and any lift you choose to ride. The official route site carries trail conditions, diversion notices and mountain-safety guidance in one place, and it is the page to read in the week before you leave. It also hosts the Casermetta Espace Mont-Blanc above Courmayeur, an information centre for hikers that is open daily from 25 June to 13 September in 2026.

Bivouac and camping rules change by country and by sector, and the Treutsebo reroute shows why you should read the official conditions page rather than relying on a printed guide. Mountain-safety advice from the local rescue organizations is published alongside the route information and is worth ten minutes before departure.

Plan Your Visit

The Tour du Mont Blanc rewards planning more than most trails because the decisions come early: which direction, how many days, which huts and which month. Settle the direction and the itinerary length first, then book the accommodation chain, then train for the climbing. The walking itself is straightforward; the logistics are what make or break the trip.

Read the official trail conditions page in the final week for diversions and sector rules, and carry a map or offline track even with red-and-white waymarks underfoot. Cross-check hut availability before you commit to a start date, and keep one flexible day in the plan for weather.
