TMB in 5 Days: Possible, but at What Cost?

Five days off, not one more. That's often where the thinking starts: can you really complete the 170 km Tour du Mont-Blanc in five days without having to run?

The answer is yes. But it comes with trade-offs.

Without a buffer day, a thunderstorm or a fog-covered pass can wipe out a stage and throw your entire plan off track. And in the mountains, pushing through bad weather to stay on schedule is a decision that safety simply doesn't allow.

Before you commit, you need to know what this express pace actually means, and especially what you won't have time to see.

At Altimood, we've hiked the TMB and all its variants. We've tested every pass, every shortcut, every possible transfer. This article lays it out honestly: here's the realistic 5-day itinerary, the sections you'll have to sacrifice, the fitness level required, and why, as professionals, we'd rather take you on the 7-day format.

Why hike the TMB in 5 days?

The reasons are usually the same: a tight window between two work weeks, a smaller accommodation budget (two fewer nights adds up), or simply the desire for an athletic challenge. The standard duration for the Tour du Mont-Blanc is 7 to 10 days. The 5-day TMB attracts trail runners who want to discover the route at a sustained hiking pace, without crossing into racing territory.

All of these reasons are valid. The problem isn't wanting to go fast. It's not realizing what the clock takes away from you.

Tour du Mont-Blanc 5-day itinerary

To fit everything into 5 stages, you need to merge certain days and use transfers (bus or taxi) on the least alpine sections. Here's a realistic itinerary, tested on the ground. The 138 km total (versus 170 km for the full TMB) is explained by the Swiss Val Ferret being replaced by a bus ride and shortcuts from merging stages.

Some agencies offer a "TMB in 5 days" that only covers the northern half of the circuit (Courmayeur to Chamonix, ~75 km), with van transfers to skip the French sections. That's not the same trek. The itinerary below covers the complete loop.

Day 1: Les Houches → Les Chapieux

Two stages in one. From Les Houches, climb to Col de Voza (1,653 m), descend to Les Contamines-Montjoie, then continue straight to Notre-Dame-de-la-Gorge and the Col du Bonhomme (2,329 m) and Croix du Bonhomme (2,479 m).

• Distance: ~36 km
• Elevation: +2,400 m / -1,850 m
• Hiking time: 10-12h
• Accommodation: Auberge de la Nova, Les Chapieux

This is the longest day. Two passes above 2,300 m in a single day, starting from 1,010 m. An early-morning start is mandatory. You'll most likely need to arrive in Les Houches the evening before.

• Distance :↔ 34.9 km
• Dénivelé positif :↗ 2286 m
• Dénivelé négatif :↘ 1709 m

Day 2: Les Chapieux → Courmayeur

Combining stages 3 and 4. Col de la Seigne (2,516 m) marks the Italian border. The landscape shifts instantly: Beaufortain alpine pastures give way to the south face of Mont-Blanc, with vertical walls and hanging glaciers. The descent crosses Val Veni, follows Lac Combal, and reaches Courmayeur.

• Distance: ~28 km
• Elevation: +1,450 m / -1,700 m
• Hiking time: 8-9h
• Accommodation: hotel or guesthouse in Courmayeur (1,226 m)

Crossing Col de la Seigne is the highlight of this day. If you're ahead of schedule, stop at the Rifugio Elisabetta terrace for a caffè with a view.

• Distance :↔ 28.5 km
• Dénivelé positif :↗ 1445 m
• Dénivelé négatif :↘ 1784 m

Day 3: Courmayeur → Champex-Lac (with transfer)

The climb to Refuge Bonatti (2,026 m) is steep, but from the terrace, the Dent du Géant (4,013 m) and Grandes Jorasses (4,208 m) stand less than 10 km away with nothing blocking the view. The trail continues to Grand Col Ferret (2,537 m), the Italy-Switzerland border, then descends to La Fouly. From La Fouly, postal buses take you to Champex-Lac in 45-50 minutes (connection in Orsières), skipping the Swiss Val Ferret stage.

• Distance on foot: ~24 km
• Elevation on foot: +1,600 m / -1,300 m
• Hiking time: 7-8h + bus transfer
• Accommodation: hotel or gîte in Champex-Lac (1,466 m)

• Distance :↔ 30.4 km
• Dénivelé positif :↗ 1771 m
• Dénivelé négatif :↘ 1389 m

Day 4: Champex-Lac → Trè-le-Champ

Two options from Champex: the classic trail via Bovine (more accessible) or the Fenêtre d'Arpette (2,665 m, more demanding). Both lead to Trient. Then continue over Col de Balme (2,204 m), back into France with the Chamonix valley spread out below. Descent to Trè-le-Champ.

• Distance: ~28 km (via Bovine) or ~30 km (via Arpette)
• Elevation: +1,700 m / -1,800 m (Bovine) or +2,000 m / -2,100 m (Arpette)
• Hiking time: 9-10h
• Accommodation: gîte in Trè-le-Champ or bus down to Argentière/Chamonix

A turning point day. The Fenêtre d'Arpette is tempting, but after three days of serious effort, Bovine offers a more sensible pace without giving up the Col de Balme panorama.

• Distance :↔ 28.4 km
• Dénivelé positif :↗ 1791 m
• Dénivelé négatif :↘ 1822 m

Day 5: Trè-le-Champ → Les Houches

Final day. Climb to the Refuge de la Flégère then traverse the south balcony of the Aiguilles Rouges, facing the Mont-Blanc chain. The Grand Balcon trail passes over Le Brévent (2,525 m) before the long descent to Les Houches.

• Distance: ~22 km
• Elevation: +1,400 m / -1,700 m
• Hiking time: 7-8h
• Accommodation: you've made it!

The Flégère-Brévent traverse rolls out 12 km of balcony trail facing the Aiguille Verte, Les Drus, and the Aiguille du Midi. If fatigue hits, the Brévent or Flégère cable car can shorten the descent.

• Distance :↔ 21.6 km
• Dénivelé positif :↗ 1352 m
• Dénivelé négatif :↘ 1788 m

What you miss in 5 days

The 5-day TMB is Mont-Blanc on fast-forward. You'll see all three countries and the major passes. But here's what gets cut:

The Swiss Val Ferret (stage 7). The trail between La Fouly and Champex crosses flowering meadows, follows the Dranse river, and passes through timber hamlets darkened by age. It's the most "Swiss" stage of the TMB, the one where the pace drops a notch. In 5 days, it gets replaced by a bus.

The Col du Tricot variant (stage 1). By merging the first two stages, you'll probably choose Col de Voza (faster) over Col du Tricot. You'll miss the suspended footbridge over the Bionnassay torrent and the plunging view of the glacier 200 m below.

Time to stop. Watching an ibex on the crest of Mont de la Saxe, lingering on the Refuge Bonatti terrace while the sun colors the Grandes Jorasses. All of that takes time, and in 5 days, time is a luxury.

Recovery. With stages of 25 to 36 km and 1,500 to 2,400 m of elevation gain per day, fatigue builds fast. By day 3, your knees and feet are reminding you that your body isn't a machine.

Required fitness level

The 5-day TMB is not a beginner trek. To attempt it:

• Experience: you should have completed multi-day treks with stages of 20 km+ and 1,200 m of elevation gain
• Training: able to hike 8 hours in the mountains without difficulty, for 5 consecutive days
• Feet and knees: conditioned for long descents. The 1,800 m of descent on day 4 is brutal on unprepared joints
• Self-sufficiency: able to read a map, manage your pace, anticipate weather, and accept adapting your plans for safety

In 5 days, there's no margin for a rest day. If the weather turns bad on a pass, you don't have a buffer day to reschedule.

Budget: 5 days vs 7 days

Five days means two fewer nights of accommodation. In a mountain hut, count on roughly 60 to 80 EUR per night for half-board. That's a savings of around 120 to 160 EUR. Add the La Fouly-Champex bus transfer (around 15 EUR).

Overall, the 5-day TMB done independently costs between 400 and 600 EUR per person (half-board accommodation, excluding round-trip transportation and packed lunches). For 7 days, count on 500 to 750 EUR. The difference is real but modest relative to the total investment (transportation, gear, time off work).

Our take: why we prefer 7 days

We won't discourage you if 5 days is all you have. The short TMB is still a powerful experience. But when you have the choice, 7 days changes the very nature of the trek. I completed my first TMB in 3 days with a full pack. Performance done, but I was perfectly happy to do it again right after with a group. The stopwatch didn't leave as many lasting images.

In 7 days, stages go from 28-36 km down to 15-20 km. Daily elevation drops from 2,000 m to 1,000 m. You shift from "performance mode" to "contemplation mode." You have time to take the variants (Col du Tricot, Col des Fours, Fenêtre d'Arpette) without redlining. You sleep better, eat better, and have time to look up.

TMB in 5 days: with or without a guide?

Doing the Tour du Mont-Blanc in 5 days without a guide is doable if you have experience with multi-day alpine treks and can read a 1:25,000 topographic map. You handle the route, hut reservations, and weather adjustments on your own.

With a mountain guide, the 5-day format becomes more comfortable: no navigation to manage, pace adjusted in real time, and the tough calls when fatigue or weather complicate things fall to someone with professional judgment.

Make the choice that fits you.

How to get to the trailhead (Les Houches)

Les Houches is accessible by train via the Saint-Gervais-Les-Bains-Le Fayet station, then a local TER connection to Les Houches (10 min). By car, long-term parking is available at the trailhead (Prarion parking lot or Bellevue parking lot). From Chamonix, the Chamonix-Les Houches bus line runs all day during the season.

When to go and hut reservations

The ideal window is between late June and mid-September. In July and August, TMB huts fill up several months in advance. For a 5-day departure, book at least 3 to 4 months ahead, especially for Les Chapieux (Auberge de la Nova) and Refuge de la Flégère, which are the most in-demand stops on this itinerary.

On the French side, the TMB doesn't cross a National Park but passes through nature reserves (Aiguilles Rouges, Contamines-Montjoie) and municipalities with specific regulations. In practice, bivouacking is limited to designated areas near huts (Croix du Bonhomme, Balme) or municipal zones (aire de la Rollaz in Les Contamines, Les Chapieux). Check the rules municipality by municipality before you go. In Italy (Aosta Valley), bivouacking is strictly prohibited below 2,500 m altitude. In Val Veni and the Italian Val Ferret, you must use official campsites or sleep in huts. In Switzerland, regulations vary by canton: in the Swiss Val Ferret (Valais), bivouacking is tolerated above the tree line but prohibited in nature reserves. Check before you leave.

Frequently asked questions

Can you do the TMB in 5 days without training?

No. Stages of 28 to 36 km with 1,500 to 2,400 m of elevation gain per day require specific preparation. Count on at least 2 to 3 months of training with long mountain outings (20 km+, 1,000 m elevation gain) before departure. The gym is a good start but doesn't fully prepare your joints for what they'll face on varied terrain.

Do you need to book huts in advance?

Yes, it's essential in summer. TMB huts (especially on the French and Italian sides) fill up fast. Book 3 to 4 months ahead for a July-August departure.

What budget should you plan for the 5-day TMB?

Between 400 and 600 EUR per person for an independent trip (half-board accommodation, excluding round-trip transportation and packed lunches). A mountain guide for a private group is an additional cost, but it's shared among participants.

Is the 5-day TMB dangerous?

The TMB isn't a technical route, but the 5-day format reduces safety margins. Without a buffer day, a thunderstorm on a 2,500 m pass or a knee injury on day 3 can compromise everything. Accumulated fatigue also increases the risk of falls on steep descents.

Can you do the 5-day TMB with kids?

No, this format is not suitable for children. Days of 8 to 12 hours of hiking and the daily elevation gains far exceed what a child can handle. For a family TMB, go with a 10 to 12-day format or selected sections.
