Tour du Mont Blanc Hike: All You Need To Know

The Tour du Mont Blanc trail forms a complete loop around the Mont Blanc massif. Most hikers tackle it counterclockwise, starting from Les Houches or Chamonix and heading south into the Bionnassay valley. This is the standard direction because it puts the most dramatic alpine scenery (the Italian side, Col Ferret, and the Swiss valleys) later in the trek, when your legs and mountain sense are better calibrated.

Counterclockwise (standard direction): You begin with a stiff climb over Col de Voza and Col de Tricot, cross into Italy via Col de la Seigne, pass through Courmayeur, traverse Col Ferret into Switzerland, and return to Chamonix over Col de la Balme and via Lac Blanc. If you start from Les Houches, you can also take the cable car to the Bellevue plateau, skipping the initial 667-metre climb to Col de Voza — a useful option if you arrive late or want an easier first day.

Clockwise direction: Less common and slightly better for crowd avoidance on certain sections. It means the steepest ascents fall on stages you approach from the opposite side, which some hikers find harder on the knees. If hut availability on the western (French) side is tight, starting from Courmayeur clockwise is a practical alternative.

Short versions: Because Chamonix and Courmayeur are connected by the Mont Blanc Tunnel (see closure note below), it is straightforward to hike only the western half (Chamonix to Courmayeur, 5 days, ~68 km) or the eastern half (Courmayeur through Switzerland back to Chamonix, 6 days). Both partial routes retain the core highlights of the circuit.

Variant routes worth considering include the Fenêtre d'Arpette (a higher, more exposed alternative to the Bovine route between Champex and Trient), Lac Blanc (a stunning balcony route on the final day back to Chamonix), and Col de Tricot (already on the standard counterclockwise route but with an alternative via Bionnassay valley). For route navigation, use the Bookatrekking app, which shows your daily trail, waypoints, and per-hut weather forecasts based on exact hut coordinates.

The Tour du Mont Blanc hike is rated moderate to challenging. The trail is well-marked and does not require technical climbing, but the cumulative elevation gain of around 10,000 metres over 10 days demands real aerobic fitness and experience with multi-day mountain walking. Anyone who walks regularly and builds up their fitness in advance can complete it. But going in underprepared will not be enjoyable.

Here is the honest stage-by-stage picture, based on our Full Tour du Mont Blanc 10-day itinerary:

Hardest days: Days 1 and 2 hit you early with over 1,300 metres of ascent each. Day 1 climbs to Col de Tricot (+1,410 m), and Day 2 covers 22.3 km with a crossing via Col du Croix du Bonhomme. Day 6 and Day 10 are the other serious endurance stages. If you find any of these days difficult, the pacing tips below apply directly.

For preparation: Start training at least 8 weeks out. Walk 4-5 days per week, with at least one long day (5+ hours) wearing your actual boots and a loaded pack. Stair climbing is one of the best single exercises for the TMB's relentless ascents. Practice descending: your quads and knees take the real punishment on the way down.

If you want an extra day: The 12-day Full Tour du Mont Blanc package with accommodation splits the hardest stages and includes arrival and departure days, making it the better choice for first-timers or those who want a more relaxed pace.

The total cost of hiking the Tour du Mont Blanc depends on how you travel, where you sleep, and whether you book independently or through a service. Here is a realistic 2025 breakdown:

Accommodation (per person per night):

• Dormitory bed in a refuge or rifugio: £30–£50 / €35–€55
• Private room in a refuge or gîte: £65–£100 / €70–€110
• Hotel in a valley town (e.g., Bourg Saint Maurice, Courmayeur): £80–£140 / €90–€150

Most huts offer half-board (demi-pension): dinner and breakfast included in the price. This typically adds £20–£35 / €25–€40 per night on top of the room price but is strongly recommended. Carrying five days of food adds weight and removes one of the genuine pleasures of this trek: sitting down to a hot meal after eight hours in the mountains.

Meals (if not on half-board):

• Refuge dinner: £20–£35 / €22–€38
• Lunch at a mountain hut or village: £12–£20 / €14–€22
• Self-catering from a supermarket (valley towns): £5–£10 / €5–€12 per day

Transport:

• Geneva to Chamonix shuttle: £35–£60 / €40–€65 (shared), £90–£150 / €100–€165 (private)
• Stage shuttle (e.g., Les Chapieux to Bourg Saint Maurice): ~£25–£40 / €28–€45 per person
• Cable cars (optional): £12–£25 / €14–€28 per ride

Equipment: If you need to buy boots, a pack, and waterproofs from scratch, budget £300–£600. If you already have gear, a typical top-up (poles, first aid kit, buffs) costs £50–£120.

Travel insurance: Mountain rescue in the Alps is not free. A policy with helicopter evacuation coverage costs approximately £50–£90 for a 14-day trek.

Rough totals for a 10-day trek (per person):

• Budget (dorms, half-board, shared transfers): £900–£1,200 / €1,000–€1,350
• Mid-range (mix of private rooms and dorms): £1,300–£1,700 / €1,450–€1,900
• Comfortable (private rooms throughout, hotels in valley towns): £1,900–£2,500 / €2,100–€2,800

The Tour du Mont Blanc is a summer trek. The main season runs from mid-June to mid-September, but the quality of your experience varies significantly by month.

June: Snow lingers on the higher passes, particularly Col de Tricot, Col Ferret, and Fenêtre d'Arpette. Some mountain huts are still closed or operating on a limited basis. Trail conditions can be icy in the morning. June suits experienced alpinists comfortable with snow travel, but it is not ideal for first-timers.

July: Full season is underway. All huts are open, the trails are snow-free, and the weather is generally warm and sunny in the mornings. The downside is afternoon thunderstorms, which are common in the Alps in July. Plan to be at or near your hut by early afternoon. July is also peak season for crowds: popular refuges like Rifugio Elisabetta and Rifugio Bonatti fill up months in advance.

Late August (the sweet spot): Crowds thin out noticeably after the first week of August as the French school holidays end. Weather tends to be stable, temperatures are comfortable for walking, and huts are still fully open. This is the period most experienced TMB hikers recommend.

September: Beautiful light, far fewer people, and crisp mornings. The risk is early-season snow on the high passes, which can arrive from mid-September onwards. Some huts begin closing in the first two weeks of September. If you go in September, check hut closing dates carefully before booking.

Weather tip: Mountain weather in the Alps changes fast. The Bookatrekking app shows the current weather forecast for each individual hut, based on that hut's GPS coordinates. Check it every evening for the next day's stage. Do not rely on valley forecasts for high-altitude conditions.

There are 110+ accommodation options along the Tour du Mont Blanc, from basic dormitory refuges to comfortable valley hotels. The key challenge is not finding accommodation; it is securing it in time.

When to book: Popular refuges for July and August dates begin accepting reservations between September and January of the preceding year. If you plan to hike in peak season, aim to have your full itinerary booked by February at the latest. For late August and September, you have more flexibility, but even then the best huts along key stages fill up fast.

Most in-demand huts: Rifugio Elisabetta, Rifugio Bonatti, Gîte Alpage de La Peule, and the Lac Blanc area accommodation consistently sell out earliest for peak dates. Have alternative huts in mind for each stage in case your first choice is full.

Half-board: Most huts offer dinner and breakfast as a package. We strongly recommend taking it. After a full day of mountain walking, arriving at a hut with a warm meal already arranged is genuinely worth the extra cost, and it means one less thing to carry.

Backup strategy: If a hut is full, look for the next village or hut on the same stage. The route passes through enough settlements that a few kilometres more (or less) can unlock availability. Flexibility in your end-of-day target makes booking much easier.

At Bookatrekking, we handle all accommodation booking for you. Our Full Tour du Mont Blanc 10-day self-guided package includes pre-arranged huts and hotels along the entire route, so the only decision you need to make on the trail is which view to stop and admire.

The 10-stage itinerary below follows the classic route, crossing all three countries and covering the full 162.7 km. It is the basis of our Full Tour du Mont Blanc 10-day trek.

Day 1: Chamonix / Les Houches to Auberge du Truc (14.8 km, +1,410 m) You climb steadily out of the Chamonix valley via Col de Voza and Col de Tricot, with glacier views opening up on the approach to the col. The descent to Le Truc is rewarding. This is one of the harder days — treat it as a wake-up call for what the TMB demands.

Day 2: Auberge du Truc to Hotel Base Camp Lodge, Bourg Saint Maurice (22.3 km, +1,320 m) The longest day in distance and the second biggest climb. You pass Notre Dame de la Gorge, cross Col du Croix du Bonhomme, and descend to Les Chapieux, from where a shuttle takes you to Bourg Saint Maurice.

Day 3: Bourg Saint Maurice to Rifugio Elisabetta (14.3 km, +990 m) A shuttle returns you to the mountains. From Refuge des Mottets, the trail climbs to Col de la Seigne — the border with Italy — with extraordinary views of the Mont Blanc massif from the Italian side.

Day 4: Rifugio Elisabetta to Rifugio Monte Bianco (9.1 km, +90 m) The easiest day on the trail. Mostly downhill along the Dora di Veny river, with views of the Miage and Brenva glaciers. Use the shorter day to rest your legs.

Day 5: Rifugio Monte Bianco to Rifugio Gio Bertone (11.3 km, +1,060 m) Down to Courmayeur (a welcome town stop) and then a sharp ascent to Rifugio Giorgio Bertone, with one of the finest views of Mont Blanc from the Italian side.

Day 6: Rifugio Gio Bertone to Gîte Alpage de La Peule (20.7 km, +1,090 m) A long, rewarding day. You pass Rifugio Bonatti, cross Col Ferret into Switzerland, and descend into the Swiss Val Ferret. The Grand Combin dominates the skyline.

Day 7: Gîte Alpage de La Peule to Relais d'Arpette (22.3 km, +680 m) Through the idyllic village of La Fouly and along the shores of Lake Champex to Relais d'Arpette, where you sleep at the foot of the Fenêtre d'Arpette for the next day's crossing.

Day 8: Relais d'Arpette to Trient (15.4 km, +730 m) Over Col de Portalo and down through forests to the village of Trient, with views over the Martigny valley. A moderate day with a satisfying descent.

Day 9: Trient to Gîte Le Moulin (14.6 km, +1,090 m) Col de la Balme returns you to France. From the top, you look back at the Swiss Alps and ahead to the Chamonix valley. Descend to Tré le Champ.

Day 10: Gîte Le Moulin to Chamonix (17.9 km, +1,300 m) The grand finale. The Southern Balcony route above the Chamonix valley passes Lac Blanc, one of the most photographed spots on the entire TMB. Note: the chairlift from the valley stops at 5 pm; plan your descent accordingly.

If you prefer a slightly more relaxed pace, the 12-day Full Tour du Mont Blanc package with accommodation included splits the toughest stages and adds arrival and departure days, making the overall experience less pressured.

Not everyone has ten days. The TMB divides naturally into two halves, separated by Courmayeur and the Mont Blanc Tunnel.

Western half (Chamonix to Courmayeur, 5 days, ~68 km): Covers the Bionnassay glacier, Col du Croix du Bonhomme, Refuge des Mottets, and Col de la Seigne. Dramatic from the start. Our Western Tour du Mont Blanc 5-day self-guided trek covers this section. If you want accommodation before and after included, the Western Tour du Mont Blanc 7-day package adds an arrival and departure day.

Eastern half (Courmayeur to Chamonix via Switzerland, 6 days): Takes in Rifugio Bonatti, Col Ferret, Lake Champex, Fenêtre d'Arpette, and Lac Blanc. When availability on the western section is tight, this is an excellent alternative. Neither half is easier than the full circuit, just shorter.

Most hikers fly to Geneva (GVA), which is 103 km from Chamonix. Direct shared shuttles run year-round and take approximately 1 hour 15 to 1 hour 30 minutes. Private transfers are also available. Lyon (LYS, ~220 km) and Chambéry (CMF, ~140 km) are reasonable alternatives if Geneva flights are expensive.

By train: TGV to Saint-Gervais-les-Bains, then a local TER service to Chamonix (around 45 minutes). From Switzerland, the scenic Martigny to Vallorcine to Chamonix route is slower but spectacular.

Good to know: The Mont Blanc Tunnel was completely closed for renovation works between 1 September and 12 December 2025 and has since fully reopened, so road and bus connections between Chamonix and Courmayeur run as normal again. Further multi-week closures are planned in the coming years as the renovation programme continues, so check the tunnel's official travel information when planning your trip.

The vast majority of hikers complete the Tour du Mont Blanc self-guided. The trails are extremely well-marked with consistent red-and-white waymarks throughout France, Italy, and Switzerland. In good visibility, the risk of getting lost is low.

That said, self-guided does not mean unplanned. You need to:

• Book all accommodation well in advance (months, not weeks, for July/August)
• Plan realistic daily distances and elevation gains
• Carry basic navigation tools for foggy or poor-visibility conditions
• Know emergency numbers for each country (France: 112 / PGHM Chamonix +33 0 4 50 53 16 89; Italy: 118 or 112; Switzerland: 144)

If you want the freedom of a self-guided trek but without the logistical headache of researching and booking each hut individually, Bookatrekking's self-guided packages handle all itinerary planning and accommodation booking for you. You arrive, you walk, we have taken care of the rest.
