Great decision!
Organizing it yourself is still the best way to make the tour your own, and the breakdown above is a solid starting point. On the TMB, the number one constraint isn't your fitness, it's booking: July and August huts fill up as early as January. Contact details and booking methods for the tour's fifty-odd accommodations are on our dedicated page. Enjoy the loop!

Go with a guide
Our guides take small groups around Mont Blanc every summer, in comfort format with luggage transport. Leave your details and we'll send you our upcoming departures.
One July evening at the Refuge Bonatti, two tables compare notes. On the left, a group is finishing the tour in 7 days: they left Chamonix by cable car, took two buses on the Swiss side, and are sleeping in hotels. On the right, another group is on day nine of twelve, carrying a 12 kg pack, on foot the whole way from Les Houches. Both are doing "the Tour du Mont-Blanc." It isn't the same trek.
How many days, or how much time, does the Tour du Mont-Blanc take? The short answer circulating everywhere is 7 to 10 days. It isn't wrong, just incomplete, because it lumps together two very different things: the number of walking days, and the number of tour days. Between the two sit transport and variants.
Here are the main duration benchmarks, and the tool at the top of the page works out yours by placing your nights at real accommodations:
10 to 12 days for the full loop on foot, with no transfers at all
10 days at the classic pace, the most comfortable format
7 to 9 days with tramway, bus, and cable car shortcuts
5 days in condensed form, for very well-trained hikers
3 to 5 days if you're aiming for half the tour rather than the full loop (or running it)
These five benchmarks are just entry points: combining variants, shortcuts, direction of travel, and starting point, the tool produces 6,453 distinct breakdowns, 811 of them without using a single transport link.
At Altimood, we guide Tour du Mont-Blanc trips every summer, and this question opens every single project. It deserves better than a round number.
The TMB is the most popular trek for a first big trip on foot, and that's exactly where it gets tricky
The Tour du Mont-Blanc is by far the most walked trek in the Alps. Many people who set out on it have never done a multi-day hike longer than two or three days. That's entirely doable, but it shifts the real question.
For an experienced hiker, the question boils down to "how much elevation gain can you handle per day?" When you're prepping your first big hike, you simply have no idea, and if you're coming from running or cycling rather than the mountains, even less so. That's why the tool at the top of the page doesn't ask that question first: it asks what you're doing today, whatever the sport, and works out the rest from there. By contrast, our GR54 calculator starts directly with the elevation gain you can handle per day: you don't stumble onto the Tour des Écrins by accident, and anyone taking it on generally already knows what elevation gain means.
One useful nuance if you're coming from another sport rather than hiking: the engine transfers, the rest much less so. A regular runner or cyclist has the lungs to climb a pass, but not necessarily the thighs or posture for a three-hour descent, or the shoulders for an eight-kilogram pack. Yet it's the descents and the carrying that produce the third-morning soreness, not the climbing. Hence the "I'm active, but rarely in the mountains" line in the tool: it's worth notably more than "I walk a little, nothing more," without being worth as much as "I hike every week." The full breakdown of what transfers and what doesn't is in our article on daily elevation gain to aim for when you're starting out.
The order of magnitude worth remembering: the TMB means 9,000 m of cumulative climbing. Divided across 12 days, that's 750 m a day, a manageable figure for a regular hiker. Divided across 7 days, that's 1,300 m a day for a full week, pack on your back, which is a whole different commitment.
What the TMB actually measures: 158 or 170 km?
Across our eleven GPX tracks, joined end to end: 158.5 km and 9,089 m of elevation gain. Other tracks available online also come out around 160 km. Depending on the hiker, an iPhone or a GPS watch will show a higher or lower figure.
Where does the gap come from? Two different places, and it's worth not mixing them up:
On distance, track sampling slightly cuts corners on switchbacks, shaving off a few hundred meters per stage. The rest comes from breakdowns that add up stages rounded up and fold in variants.
On elevation gain, it all depends on smoothing. The same track gives 11,151 m unsmoothed (GPS noise inflates every micro-bump) and 9,089 m smoothed. The 10,300 m figure sits between the two. None of these numbers is dishonest, they simply don't measure the same thing.
These gaps aren't trivial: 12 km is half a day's walking, and 1,200 m of elevation gain is a full day. On a 7-day schedule, that matters. The tool calculates from the measured values, and you'll know where they come from and how to read the difference once you're on the ground.
Shortcuts: the lever other treks don't have
This is what really sets the TMB apart from the GR54 or the traverse of the Vercors Hauts-Plateaux. On those routes, if the days are too tough, the only lever is to walk more or wild camp. Around Mont Blanc, the tour crosses three well-equipped countries: a tramway, Swiss postal buses every quarter hour, cable cars. Skipping a section isn't cheating, it's common practice, including on organized trips.
The four shortcuts offered in the tool correspond to real, bookable services:
Shortcut
What it skips
Saving
Tramway du Mont-Blanc
the climb from Les Houches to Col de Voza, up the ski runs
−6.8 km, −708 m
Postal bus La Fouly → Champex
the flat floor of the Swiss Val Ferret, easy and effortless
−15.4 km, −443 m
Postal bus Champex → Trient
the Bovine alpine pasture and the Col de la Forclaz
−15.2 km, −726 m
Flégère cable car
the long final descent to Chamonix
−15.5 km, −660 m
Together, the four remove 53 km and 2,500 m of elevation gain, roughly three to four days. That's exactly what lets a regular hiker complete "the Tour du Mont-Blanc" in a single week of vacation.
A point of honesty: our own 7-day trip works the same way, but it relies on private transfers. Stages of 4 to 6 hours, elevation gains of 600 to 1,200 m, hotel nights, luggage transported, and four transfers. A 7-day TMB with no transfers at all takes around 1,300 m of elevation gain a day, pack on your back: that's an entirely different exercise.
The corollary is worth saying out loud: if you see "TMB in 7 days" advertised somewhere with no mention of transfers, ask for the stage-by-stage detail before booking.
Which shortcuts should you pick? The ones that cut the least varied or most developed sections, not the high balcony trails. The first three in the table replace a climb up ski runs, flat valley floor, and the Bovine pasture. The balcony route between Refuge Bertone and Refuge Bonatti, facing the Grandes Jorasses, or the climb to the Grand Col Ferret: those are the reasons you came. Don't skip them, unless you're genuinely pressed for time (and if you are, why not spread it over two years?).
The full TMB on foot: 10 to 12 days
The entire loop, on foot, without stepping into a single vehicle: that's what the tool calculates first. For a regular hiker who can handle 1,100 m of elevation gain a day, that comes to 12 days with days of 4 to 6 hours. For someone who has already done several consecutive trek days and can absorb 1,400 m, that tightens to 10 days, but the days stretch to 7 hours of walking.
Where does the gap with the eleven stages everyone quotes come from? From the fact that those eleven stages aren't days. It's a descriptive grid, built around the accommodations, and its days are very uneven: from 3 hours to more than 8. Almost no one walks it exactly as laid out, and confusing the two leads to missed bookings.
The other reason for the gap comes down to how you count. Elevation gain alone is misleading: 1,350 m of pure climbing tires you less than a day of 1,100 m up followed by 1,100 m down, where your thighs pay twice. So the tool calculates a walking time, with climbing and descending counted at different speeds, then looks for the breakdown that best balances the days between accommodations that actually exist. The stages we detail one by one in the full article on the tour follow the classic grid. The tool, on the other hand, rebuilds yours, and it factors in the eleven TMB variants if you want to see what they do to your breakdown.
One constraint nothing can smooth away: bed availability. The loop counts around fifty addresses, and the most sought-after fill up as soon as booking opens, often six months ahead. So you don't build your ideal breakdown, you build with what's left. One day stretches because the halfway hut is full, the next shortens because the following one is too, a variant gets dropped because it passes far from the only place you had a bed. Book first the nights where only one or two addresses exist: those are what lock everything else in place. Our roundup of the Tour du Mont-Blanc mountain huts maps them out with altitude, comfort level, and opening dates, so you can spot the tight sectors right away.
One last piece of advice, and it's the one we give most often: plan shorter than you think you can manage. A comfortable day can always be stretched on the spot, just add a high-altitude variant when the weather and your legs allow it. The reverse can't be undone. A breakdown built around your best day leaves no room for a storm rolling in at 2pm, a knee that starts complaining, or the third day in a row catching up with you. All that's left then is the transport shortcut, and it's better if it's a treat you give yourself rather than an emergency exit.
Finally, it's the most demanding format in terms of vacation time: allow two full weeks including travel from home to the Arve valley.
The TMB in 10 days: the classic pace
At 15 km and 900 m of elevation gain a day on average, days last 5 to 7 hours. You reach the hut in mid-afternoon, there's slack left on mornings when a storm forces an early start, and you can afford variants like the Lac Blanc without watching the clock.
It's the format we recommend most often to regular hikers who want to see the tour, not just cross it. We've detailed it stage by stage, along with the variants this pace makes accessible, in our article on the Tour du Mont-Blanc in 10 days.
One or two shortcuts are then enough to bring the trip down to 8 or 9 days if your vacation time is limited.
The TMB in 5 days: the condensed version
25 to 30 km a day, transfers to skip entire sections, and days that run past 8 hours. This format exists, it works, but it's for very well-trained hikers who know exactly how their body handles four big consecutive days.
We've detailed what it really costs, and what it makes you miss of the tour, in our article on the Tour du Mont-Blanc in 5 days.
Not enough vacation time? Do half the tour
It's the advice we give most often, and the one people follow the least. If you have four or five days and don't walk much otherwise, a half-loop taken at an easy pace will leave you with a far better memory than the full loop rushed through.
The tour splits naturally in two at Courmayeur and Chamonix, both well served and linked by the tunnel:
French and Italian side (Les Houches → Courmayeur): the Col du Bonhomme and Col de la Seigne, the Val Veny, the south face of Mont Blanc. Four to five days.
Italian and Swiss side (Courmayeur → Chamonix): the Grandes Jorasses balcony route, the Grand Col Ferret, the Swiss alpine pastures, Col de Balme. Four to five days.
One summer each, and you'll have done the full tour without ever taking two weeks off in one go. It's also the best way to gauge yourself before committing to the full loop.
If your main goal is to prepare, a shorter multi-day hike remains the best test run, and it's day 3 that tells you the most. Our article on the daily elevation gain to aim for gives ranges by profile, and a 3-day hike with hut stays is enough to place yourself.
What can derail your schedule
Fully booked huts. By far the number one cause of a derailed schedule on the TMB, ahead of fitness. In high season, the tour's huts show full from early in the year. Book before you lock in your stages, not the other way around. The full accommodation list gives contact details and booking methods.
Early-season snow patches. In late June and early July, the Col des Fours and the Fenêtre d'Arpette can still hold snow. Our page on when to do the TMB breaks down the windows month by month.
Summer storms. The rule of crossing passes before 1pm can shorten a stage planned as a double day. A spare day in the schedule isn't a luxury in July and August.
Pack weight. Self-sufficient with tent and stove, progress slows noticeably, especially downhill. Note that wild camping is regulated across a large part of the route: see our page on bivouacking around Mont Blanc before building a schedule around it.
Three currencies. France, Italy, Switzerland. Swiss huts cost noticeably more, and not all of them take cards.
Doing the tour with a guide
The number of days also depends on who's handling the logistics. On a guided trip, the stages are calibrated, huts and transfers booked before departure, and luggage follows by road. A few variants get added in to take in an edelweiss patch or a spot where chamois can regularly be seen.

Frequently asked questions
How many kilometers per day on the Tour du Mont-Blanc?
On a full 12-day tour, the average works out at around 13 km and 750 m of elevation gain per day. Over 10 days, it rises to around 16 km and 900 m. Over 7 days with transfers, stages run around 15 to 18 km for 600 to 1,200 m. Distance alone is misleading: an 11 km stage crossing a pass demands more than an 18 km stage along a valley floor.
Does the Tour du Mont-Blanc really cover 170 km?
Our eleven tracks joined end to end give 158.5 km for 9,089 m of elevation gain. The 170 km figure often quoted comes down to three things: stage rounding, variants folded into the breakdown, and above all elevation smoothing. The same track gives 11,151 m unsmoothed and 9,089 m with standard 7-point smoothing.
Can you do the Tour du Mont-Blanc in 7 days without transfers?
It's possible but very demanding: you need to hold around 1,300 m of elevation gain and 23 km a day for a full week, pack on your back, meaning days of 8 to 9 hours. Almost every 7-day package on the market, including ours, actually uses bus or cable car transfers to skip sections. If a 7-day offer doesn't detail its transfers, ask for the stage-by-stage program.
Does the TMB take more days than the GR54?
No, fewer. The TMB can be completed in 10 to 12 days on foot, while the GR54 takes 12 to 13 days: the Écrins loop is longer (188 km) and climbs 11,000 m over more technical terrain, with fewer resupply points. The TMB does have one thing the GR54 doesn't: public transport all along the route, which lets you tighten the trip without lengthening the days.
Should you plan a rest day on the Tour du Mont-Blanc?
On formats of 10 days or more, a half-day break at Courmayeur or Champex-Lac often changes the second half of the tour for the better. Both villages let you restock, sleep down in the valley, and do laundry. If your schedule is tight, plan at least one short stage midway rather than a non-stop run.
Which direction should you walk the Tour du Mont-Blanc?
The tour is very predominantly walked counterclockwise, the direction used in guidebooks: it's the smoother waymarked direction, and the one where you climb the Trè-le-Champ ladders rather than descend them. Going clockwise, you meet the crowds head-on instead of following them, which has its charm if you're after some quiet, but you descend the equipped sections, which is less comfortable if exposure bothers you. The number of days doesn't change either way. The detail of exposed sections by direction is in our article on the TMB for those afraid of heights.
