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

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

The answer is yes. But there's a price to pay.

Without a buffer day, a thunderstorm or a pass lost in fog can knock out a stage and throw your whole plan sideways. And in the mountains, pushing through bad weather just to stick to a schedule is a decision that safety won't allow.

Before you go, you need to understand what this express pace actually involves, and above all what you won't have time to see.

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

Why do the TMB in 5 days?

The reasons tend to be the same: a tight gap between two working weeks, a smaller accommodation budget (two fewer nights does make a difference), or simply the pull of a physical challenge. The standard duration for the Tour du Mont-Blanc is 7 to 10 days. The 5-day TMB draws trail runners who want to experience the route at a strong hiking pace, without crossing into full-on racing.

All of those reasons are fair enough. The issue isn't wanting to go fast. It's not grasping what the clock takes away from you.

Tour du Mont-Blanc 5-day itinerary

To squeeze 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 (compared to 170 km for the full TMB) comes from the Swiss Val Ferret being replaced by a bus and the shortcuts that merging stages creates.

Some agencies sell a "TMB in 5 days" that only covers the northern half of the circuit (Courmayeur to Chamonix, roughly 75 km), with van transfers skipping the French sections. That's a different trek entirely. The itinerary below covers the full loop.

Day 1: Les Houches → Les Chapieux

Two stages merged into one. From Les Houches, climb to Col de Voza (1,653 m), descend to Les Contamines-Montjoie, then keep going 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 by far. Two passes above 2,300 m in a single day, starting from 1,010 m. Getting away at dawn is non-negotiable. You'll almost certainly want 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 immediately: Beaufortain pastures give way to the south face of Mont-Blanc, with vertical rock 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)

The crossing of Col de la Seigne is the highlight of the day. If you find yourself ahead of time, 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 sightline. The trail continues to Grand Col Ferret (2,537 m), the Italy-Switzerland border, then descends to La Fouly. From La Fouly, postal buses bring you to Champex-Lac in 45-50 minutes (changing at 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 choices from Champex: the classic route via Bovine (more accessible) or the Fenêtre d'Arpette (2,665 m, more committing). Both lead to Trient. Then carry on 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 steadier rhythm 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

Last 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 crosses 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're done!

The Flégère-Brévent traverse gives you 12 km of balcony trail facing the Aiguille Verte, Les Drus, and the Aiguille du Midi. If the legs are gone, 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 left behind:

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

The Col du Tricot variant (stage 1). By merging the first two stages, you'll most likely pick Col de Voza (quicker) over Col du Tricot. You'll miss the suspended footbridge over the Bionnassay torrent and the view straight down onto the glacier 200 m below.

Time to stop. Watching an ibex on the ridge of Mont de la Saxe, sitting on the Refuge Bonatti terrace while the sun catches the Grandes Jorasses. All of that takes time, and in 5 days, time is scarce.

Recovery. With stages of 25 to 36 km and 1,500 to 2,400 m of ascent each day, fatigue stacks up quickly. By day 3, your knees and feet are letting you know the body isn't a machine.

Required fitness level

The 5-day TMB is not a beginner's trek. To take it on:

• Experience: you should have done multi-day treks with stages of 20 km+ and 1,200 m of ascent
• Training: able to hike 8 hours in the mountains without trouble, for 5 consecutive days
• Feet and knees: well used to 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 changing plans for your own safety

In 5 days, there's no room for a rest day. If the weather closes in on a pass, you don't have a spare day in your pocket.

Budget: 5 days vs 7 days

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

All in, the 5-day TMB done independently costs between 400 and 600 EUR per person (half-board accommodation, not including return travel or packed lunches). For 7 days, expect 500 to 750 EUR. The difference is real but modest when set against the overall investment (flights, gear, time off work).

Our view: why we prefer 7 days

We wouldn't put you off if 5 days is all you've got. The shorter TMB is still a grand experience. But when there's a choice, 7 days changes the nature of the trek entirely. I did my first TMB in 3 days with a full pack. Job done, but I was more than happy to go straight back and do it again with a group. The stopwatch didn't leave nearly as many lasting images.

In 7 days, stages drop from 28-36 km to 15-20 km. Daily elevation comes down 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 running yourself into the ground. You sleep better, eat better, and have the 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 achievable if you have experience of multi-day alpine treks and can read a 1:25,000 topographic map. You handle the route, refuge bookings, and weather calls yourself.

With a mountain guide, the 5-day format becomes far more comfortable: no navigation to worry about, pace adjusted in real time, and the hard decisions when fatigue or weather complicate matters fall to a professional.

Go with whatever suits you best.

How to reach the start (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-stay parking is available at the trailhead (Prarion car park or Bellevue car park). From Chamonix, the Chamonix-Les Houches bus runs throughout the day in season.

When to go and refuge bookings

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

On the French side, the TMB doesn't pass through a National Park but crosses nature reserves (Aiguilles Rouges, Contamines-Montjoie) and communes with specific by-laws. In practice, bivouacking is channelled to designated areas near refuges (Croix du Bonhomme, Balme) or communal zones (aire de la Rollaz in Les Contamines, Les Chapieux). Check the rules commune by commune before heading off. 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 refuges. 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 go.

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 ascent per day demand specific preparation. Allow at least 2 to 3 months of training with long mountain outings (20 km+, 1,000 m ascent) before you go. The gym is a decent start but won't fully prepare your joints for what they'll face on varied terrain.

Do you need to book refuges in advance?

Yes, it's essential in summer. TMB refuges (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, not including return travel or packed lunches). A mountain guide for a private group is an additional cost, but it's split among participants.

Is the 5-day TMB dangerous?

The TMB isn't a technical route, but the 5-day format narrows safety margins. Without a buffer day, a thunderstorm on a 2,500 m pass or a knee injury on day 3 can put the rest in jeopardy. Accumulated fatigue also raises the risk of falls on steep descents.

Can you do the 5-day TMB with children?

No, this format isn't suitable for children. Days of 8 to 12 hours of hiking and the daily elevation gains are well beyond what a child can manage. For a family TMB, look at a 10 to 12-day format or selected sections.
