The Wild Side
A spectacular alpine route circling the massif of Mont Blanc — the roof of the Old Continent — and crossing the borders of Italy, France and Switzerland. Once considered a horrific place, inhabited by demons and dragons, turns out to be an incredible display of alpine beauty where sheer granite walls rise between impending glaciers, long gravelly moraines, meadows and enchanted valleys.

The mountains before the 18th century were considered arcane places, full of dangers, inhabited by monstrous creatures, where huge white dragons (i.e. glaciers) descended from the heights to haul away and devour those who wished to violate their territory. The conquest of Mont Blanc in 1786 marks the beginning of a different approach to the mountains, still an unknown place yet to be explored — the birth of Alpinism.

A different approach is also necessary when bikepacking the Tour du Mont Blanc (TMB), one of the most popular long-distance circular treks in Europe. The urge to pedal must meld with the attitude of the mountains and to all that it involves. The Tour du Mont Blanc is an alpine voyage that fills the heart and empties the lungs.

  • Amazing views on Val Veny and Val Ferret, two beautiful glacial valleys that run along the entire italian side of the Mont Blanc Massif.
  • The monuments of the conquest of Mont Blanc (1786) in the Chamonix square. The first of 1887 is dedicated to Balmat De Saussure and the second was opened 100 years later to return M.G.Paccard about who was the real soul of the undertaking.
  • The bearded vulture (Gypaetus barbatus) it’s one of the biggest vulture which nesting in the old continent. It’s possible to spot this rare bird of prey, recently reintroduced on the Alps, in the most mountainous areas of the route.
  • The Marmot (Marmota) a sort of large squirrel, will accompany you along most of the route with its typical whistle. It’s a warning signal used to communicate your presence to the others marmots. It’s indeed the cutest animal of the TMB.
  • Weird wooden sculptures along the trail in the wood after Champex-Lac, in Switzerland.
  • This route of TMB deviates from the classic route and requires good physical preparation. However, there are several paths to reduce the total ascent and bypass some of the toughest climbs.
  • The best time to face the TMB is from mid-June until mid-September. In June the higher mountain passes may still be snow-covered. During July and August the trails are crowded with hikers, while in later September you can experience the TMB in amore intimate way.
  • The TMB can be ridden clockwise or counterclockwise. Many people choose to start from Chamonix or Les Houches in France, others from Courmayeur in Italy, but you can choose any point along the route.
  • Take high mountain clothes with you. Abrupt changes in weather can lead to sudden snowfalls even in the summer months.
  • Don’t’ forget to wear sunscreen.
  • The long, steep descents and the weight of the bike in bikepacking mode devour the brake pads. Take with you at least one spare pair.
  • In the towns of Chamonix and Les Houches, there are some well-stocked bike shops.
  • Wild camping is not generally encouraged, but is tolerated. Set up camp in responsible places. Be discreet. #leavenotrace
  • For those who don’t want to have a self-supported adventure there are many shelters along the route where you can sleep and eat. In the summer months, given the turnout, it’s recommended to book, while from mid-September many of them are already closed.
  • The massif of Mont Blanc with its glaciers and permanent snow ensures a steady supply of water along the route. (Rivers and creeks in the mountain/ fountains in the villages).
  • You can resupply at the general stores in Courmayeur (Italy), Les Houches and Chamonix (France) and in the small village of Le Fouly (Switzerland).

Trail Description

The TMB starts in a clockwise direction from Courmayeur, a small italian town located at the foot of the southern side of Mont Blanc. It quickly reaches 2,000 meters in altitude and the majestic scenery offered by the Aiguille Noire de Peuterey and the mighty glacier of Brenva that flows down valley from the summit of Mont Blanc. By way of a hike-a-bike trail you reach the Mont Favre at 2400mt before falling back to the most spectacular area of the Val Veny, where Dora of Vény river, the incredible Miage glacier, lake Combal, Aiguille des Glaciers and the unmistakable silhouettes of Calcaires Pyramides on the horizon paint an ice-age setting of incomparable beauty.

A comfortable gravel road runs through the valley and after passing some dilapidated military barracks, reaches the high Val Veny, a vast isolated plateau that allows you to catch your breath before start to climb again along a trail that leads to the Col de la Seigne (2512mt) on the border between Italy and France. Arriving here just before sunset means you will enjoy the most beautiful descent of the whole Tour immersed in a surreal atmosphere: the sweet flowing singletrack, the Vallée des Glaciers and peaks on the horizon, all is dyed of gold. After losing about 1000 mt in altitude and passed the small village of Les Chapieux, it rises again to face one of the toughest stretches of the TMB, the climb to the Col du Bonhomme (2,483mt) where the narrow, steep and often rough track will make you curse every the added grams loaded on your bike. However, the Alpine environment and the scenic views offered by the surrounding valleys will reward the effort.

The singletrack descent, initially tight and technical, becomes smoother and comfortable as you get closer to the valley where a gravel road leading into the town of Les Contamines. From here you’ll climb a steep fire road to reach Col de Voza, then cross the tracks of the Tramway du Mont Blanc to go down to the village of Les Houches, along an old school crumbly downhill track. The route continues on singletrack through the forest, running along the north side of the Arve valley, where through the branches of the pine trees, you see the majestic Glacier du Bossom and overhanging peaks of the Aiguille du Midi and the Aiguille du Dru.

After the traditional alpine village of Chamonix, you will reach the town of Le Tour where a jeep road reaches the Col de Balme at 2195mt on the border of France and Switzerland. From here a long, scenic singletrack runs the west side of the Croix de Fer and then enters the forest, where it becomes rocky and very technical. From the valley of Trient you’ll climb to the amphitheater of the namesake glacier to overcome the glacial river through a wooden bridge and reach the pass of the Col de la Forclaz. A steep narrow path climbs to the Alp Bovine becoming increasingly challenging in the final stretch where boulders along the trail force you to lift the front wheel.

The route continues between alpine pasture and forest to reach the valley bottom through a steep descent on loose rock that winds between boulders and ancient trees uprooted by winter avalanches. Back in the valley you’ll climb the swiss side of Val Ferret, cross the village of Le Fouly and with a succession of trails and fire roads you reach the Col du Grand Ferret at 2,537 mt altitude, on the Swiss-Italian border. From here the view of the Italian Val Ferret is breathtaking. The return to Chamonix is done by traversing the mountain side, a panoramic balcony on the northeastern side of the Mont Blanc massif: from Mont Dolent to the Aiguille de Triolet, from the Grandes Jorasses to the Giant’s Tooth, until the 4810mt summit of Mont Blanc.

  • Tom Hughes

    Hi, can this be done on a cyclocross bike? Thanks, Tom


    Hi Tom, a rigid/Plus bike or a classical/front suspended one is the best choice to ride this route. Ciao

  • Bryant

    Hi guys great looking trip, I tried doing this in 2013 but was informed by a couple of guides we came across that bikes were not allowed on the trail, has this changed? Admittedly we started in Chamonix and were at a lot higher elevation than is showing on your gps file.

  • Bob

    I’m surprised you’ve chosen to ride classic bikepacking bikes, with no suspension.
    Why didn’t you use mountain bikes on this mountain loop ?


    Thanks Bryant. Yes, from July to August bikes are not allowed on the north side of the Arve valley, where the classic hiking route passes on the highest part of the mountains. This bikepacking route runs along the valley at a lower elevation (1000 mt) than the official TMB trek.


    Hi Bob, we used mountain bikes with 27,5 x 3″ tires. The “plus” of that size is that it works as a suspension too! ;-)

  • Dave

    Incredible views! Looks hard.


    Thanks Dave! Yes, it’s super hard but it’s worth it!

  • Charles

    Hi, I love the idea. It seems wonderfull. Do you think there would be any possibility to do it end of january or is dealing with snow too much or too dangerous?

  • Suen

    What do you think about doing this route in mid-April? Maybe is to cold? Shelters are open?

  • Sy Bro

    Again Montanus, you make me dream…. wonderful image!!!! i wish you would made a movie about it?

  • Didier Revol

    I will realize this ride with my all-suspended bike. I choose to do it with a trailer (knowing the luggage problems with a all-suspended bike). Is it realistic to make that choice? Or should I continue my research to find the best suit luggage?

  • BojoFred

    Just Forget this crazy idea my friend… it will be impossible to ride properly with a trailer !

  • Anne

    WoW! Amazing! What kind of printed map could you recommend for the trip?

  • sam

    There is still snow in april. Usually, these trails are uncovered of snow around june depending on snow conditions during winter season. Huts open in the same time of snow melting/disapearing : mid june to mid september.

  • Vaibhav Bhat

    Hi! I am planning to do this alone, in 4 days, going counter clockwise from Chamonix. Should be doable, right? That’s only 25 miles per day on a bike. Additionally, since it’s summer I’m not worried about being alone as I’ve been told there will be a sufficient amount of people on the trail at this time of year.


    Hi Vaibhav, we rode the TMB in five days (self-supported), but we stopped a lot of time for taking photos. I think you can ride it in 4 if you are in good shape. Yes, 25 miles per day, but don’t forget the 8.040 m of total ascent and some challenging “Hike-a-bike”. July will be plenty of people, don’t forget a bell! ;-)

  • Vaibhav Bhat

    Well, the way my trip worked out is wacky. I’m doing it this weekend. First day only 20miles, second day 60miles/15000ft, third day only 25 miles. Wish me luck!!!!


    Nice! Have fun and enjoy those incredible landscapes!

  • Alan

    I just rode this route in perfect weather and conditions. All was good until the descent from Col de Voza near the end. There must be a better way down than the derelict DH track that the route takes? The broken wooden sections are very dodgy, it must have been abandoned many years ago.

  • Matt

    Hey guys! looks like a really rad trip!

    It looks like you guys camped and cooked for yourselves- I’m wondering if it’s at all possible to do this route as a hut to hut- save the space of carrying camping equipment/stoves/fuel

  • Matt

    Just saw the camping tab above in which you mention huts. Any info or resources on how to book them or where they are?

  • tadas

    returned from this trip on sunday. hardest in all means trip in my life :) on the third day both me and my companion got stomach infection (most probably from water – filter no matter how good and tasty it looks :) and all went down from this moment :) we did it like in this track, but 2 sections in swiss side are forbidden for bikes, there are signs to rideabouts for mtb. also descend from col de Balme (france/swiss) is forbidden, there’s roundabout on the left side of the mountain

    anyway, fantastic trip, thank you very much

  • tommy

    I am curious to know how you passed that snow patch so close to a ditch! that single track looked pretty narrow, almost like a switchback.

  • Rueben m-g

    Arrived home from my first backpack adventure on this route yesterday, I’d taken the train into Martigny and went anti-clockwise to Chamonix on my AM bike. Although this is, in retrospect, I definitely would’ve taken a full day pack and stayed in the refuges. This way the (extremely tough) hike-a-bike segments would be much easier and taken full advantage of the world class descents without a fully loaded bike. Oh well!
    Unfortunately the weather was far from ideal and I ended up seeing mont blanc for a grand total of 40 mins in the 5 days it took – but thats all part of it! So if your planning this it’ll be worth timing it with the forecast.
    Wonderful write-up guys, you’ve inspired the first adventure!


    In what period of the year did you did the trip. Was it offseason, in September? We are thinking of doing the trip in the last week of September and we ware wandering about the temperature? :D Thanks!

  • S E

    Hi Rueben, would you recommend doing it anti-clockwise or clockwise to optimise the descending fun? I’m planning to leave on Saturday.

  • Rueben m-g

    I would personally recommend going anti-clockwise, although hiking down some descents are required regardless of direction, this way you’ll enjoy the longer, less steep (aka hike-a-bike) descents and gives you the option climb through some valleys via the road. (P.S, take the bellevue lift station up from Les Houches to avoid a gruelling hike a bike, and coming into Courmayer from Val Veny, follow the road! not the TMB signs).
    Good luck!

  • S E

    Thank, much appreciated. I would have gone clockwise (for no reason at all).

  • Richard Sumner

    Firstly thanks Giorgio and Francesco for your story, fantastic photos and information – these inspired me to go and do the route the second week of September. I did it clockwise, self contained and solo. Camped in the valleys where company and a hot shower at the end of day was often well needed after some wild crossings of the cols in snow, horizontal rain and mist. I met some great people along the way – both walkers and bike packers (JJ and Laura? from Nelson NZ please get in touch through FB). The journey was epic, a challange, greatly rewarding and has left me with an enormous sense of achievement. The huts and campsites will soon be closing as snow starts to claim the mountains. So anyone planning on a late season trip would best have experience of travel in the mountains, happy with all that can come your way in such places and carry the appropriate kit. The trails also turn to mud pretty quickly after rain – which slows things down. Looking beyond the details and those moments of hesitation we have about whether or not we commit to a trip – put simply, for me the TdeMB was superb!

  • Darren Clark

    Flights booked and super excited for this trip now – doing it on my fatbike at the end of March, hopefully the snow will make it even more fun! wild camping on the top of peaks for spectacular morning coffee views and even more spectacular sunsets hopefully.

  • Luc Mockridge

    Hi. I was just wondering if i would be able to do this on my regular hardtail and not a fatbike in March due to the snow? If there is some of course. Cheers 🚵🏼‍♀️

  • Martial Herdewyn

    ride the TMB clock wise other wise you will have to face very long hike a bike sections and shity descents for sure! If you ride it conter clockwise, you ll have to hike uphill while you could ride if you ride clockwise.

  • Natalie Jones

    Hi Montanus, thank you for your knowledgeable responses. I am planning to mountain bike the route in August of this year 2018 starting in Chamonix. I was informed that I should be pre booking the Refuges as they can be full. I want to ride it in 5-6 days. I have seen previous comments on the direction. Which direction would you recommend? and are there spots you would recommend to stop at. Im assuming shorter days on the more difficult sections and longer on the easier. Sorry for all the questions but I want to prebook the accommodation as suggested. Many thanks in advance!! Natalie
