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

Five days off, not one more. That's usually where the thinking starts: can you actually knock off the 170 km Tour du Mont-Blanc in five days without having to break into a jog?

The answer is yes. But it's not without trade-offs.

Without a buffer day, a thunderstorm or a fog-covered pass can wipe out a stage and throw your whole plan off. And in the mountains, pushing through bad weather just to keep to a schedule is a call that safety simply won't let you make.

Before you book those flights from Australia, you need to know what this express pace actually means, and above all what you won't have time to see. You've come a long way for this. It's worth understanding the full picture.

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 straight: here's the realistic 5-day itinerary, the sections you'll have to skip, the fitness level required, and why, as professionals, we'd rather take you on the 7-day format.

Why do the TMB in 5 days?

The reasons are usually the same: a tight gap between two working weeks, a smaller accommodation budget (two fewer nights adds up), or just the pull of a solid physical 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 experience the route at a strong hiking pace, without tipping into racing.

For Australians especially, fitting the TMB into a broader European trip often means working with a tight schedule. All of those reasons are fair. The problem isn't wanting to go fast. It's not realising what the clock takes away from you.

Tour du Mont-Blanc 5-day itinerary

To fit 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) comes from the Swiss Val Ferret being replaced by a bus ride and the shortcuts that come from merging stages.

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 to skip the French sections. That's a completely different trek. The itinerary below does the full loop.

Day 1: Les Houches → Les Chapieux

Two stages in one hit. From Les Houches, climb to Col de Voza (1,653 m), drop down to Les Contamines-Montjoie, then push straight on 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 biggest day. Two passes above 2,300 m in a single day, starting from 1,010 m. Getting away at first light is non-negotiable. You'll almost certainly 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 flips: Beaufortain 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 ends in 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 standout moment 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 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 options from Champex: the classic track 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 laid 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 crunch day. The Fenêtre d'Arpette is tempting, but after three days of hard yakka, Bovine offers a more sensible 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've made it!

The Flégère-Brévent traverse delivers 12 km of balcony trail facing the Aiguille Verte, Les Drus, and the Aiguille du Midi. If the legs have had enough, the Brévent or Flégère cable car can cut the descent short.

• 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, and passes through timber hamlets darkened by age. It's the most distinctly Swiss stage of the TMB, where the pace drops back a gear. In 5 days, it gets swapped for a bus.

The Col du Tricot variant (stage 1). By merging the first two stages, you'll probably 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 hits the Grandes Jorasses. All of that takes time, and in 5 days, time is a luxury you don't have.

Recovery. With stages of 25 to 36 km and 1,500 to 2,400 m of elevation gain each day, fatigue stacks up quickly. By day 3, your knees and feet are making it clear your 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 elevation gain
• Training: able to hike 8 hours in the mountains without trouble, for 5 consecutive days
• Feet and knees: well 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 changing plans for safety

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

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 up, the 5-day TMB done independently costs between 400 and 600 EUR per person (half-board accommodation, not including return flights or packed lunches). For 7 days, expect 500 to 750 EUR. The difference is real but modest next to the overall outlay (flights from Australia, gear, time off work).

Our take: why we prefer 7 days

We wouldn't talk you out of it if 5 days is all you've got. The shorter TMB is still a strong experience. But when you have the choice, 7 days changes the nature of the trek entirely. I did my first TMB in 3 days with a full pack. Performance done, but I was perfectly 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 time to look up. Given how far you've travelled to get here, the extra two days are worth it.

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 bookings, and weather calls yourself.

With a mountain guide, the 5-day format becomes a lot more comfortable: no navigation to worry about, pace adjusted in real time, and the tough calls when fatigue or weather complicate things fall to someone who does this for a living.

Go with whatever suits you.

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. If you're flying in from Australia, Geneva is the closest major airport, with bus and train connections to Chamonix taking around 2 hours.

When to go and hut bookings

The ideal window falls 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 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 regulations. In practice, bivouacking is limited 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 you head 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 elevation gain per day require proper preparation. Allow 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 decent start but won't fully prepare your joints for what they'll cop 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, not including return flights or 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 put the rest in jeopardy. Accumulated fatigue also raises the risk of falls on steep descents.

Can you do the 5-day TMB with kids?

No, this format isn't 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.
