Tour du Mont Blanc - FAQs

The Tour du Mont Blanc (TMB) is one of the most iconic long-distance treks in Europe, circumnavigating the Mont Blanc massif and covering approximately 170 km (105 miles) through France, Italy, and Switzerland. It offers breathtaking alpine scenery, diverse landscapes, and a mix of cultural experiences. The Tour du Mont Blanc features in the World’s top ten 'must do' treks.

The TMB is a challenging trek with significant daily ascents and descents. It requires good fitness and stamina. Guided treks offer the support of a guide, while self-guided options require strong navigation skills and self-sufficiency.

TMB TREK GRADING - GRADE 3: DIFFICULT

Treks are graded 1-4 (low to high) with 1 being relatively easy and 4 being the toughest. The Tour du Mont Blanc is a grade 3 trek. Described as difficult, the TMB is hard and physically demanding. You will be travelling over rugged and mountainous terrain with a sustained amount of ascent and descent on a daily basis. You can expect to hike roughly 15km (10 miles) each day with a height gain and descent of 1,000 metres (4,000 ft).

The TMB Full Guided Trek takes 10 days with 12 nights accommodation.

Shorter treks - A ‘Best of’ trek, Easterly or Westerly trek routes are available and take between 4-6 days.

The trek is best done from mid-June to mid-September, when the mountain passes are snow-free and accommodations are open. Early-season treks (June) may have some lingering snow, while late-season treks (September) offer quieter trails and cooler weather.

If you feel, for whatever reason, you are unable to fully complete the trek, it will be necessary for you to return to your start or finish hotel, using public transport. If you inform the Mont Blanc Treks office, we will try and help with your arrangements. This will incur extra charges for any extra accommodation that may be necessary and unfortunately will result in you forfeiting any already booked accommodation on the trek which you may not have used.

We run our guided treks with between 2 and 10 people. We don't oversubscribe our groups to ensure that each client enjoys their time with the guide and the group and that the group remains safe.

Col du Bonhomme & Col de la Croix du Bonhomme (France)

A long and sustained ascent from Les Contamines (1,150m) to Col du Bonhomme (2,329m), followed by another steep climb to Col de la Croix du Bonhomme (2,483m). The climb is exposed, often snowy early in the season, and followed by a long descent to Les Chapieux.

Col de la Seigne (France - Italy)

A long ascent from Les Chapieux (1,549m) to Col de la Seigne (2,516m) marking the border between France and Italy. Strong winds, unpredictable weather, and a steep final push to the top.

Grand Col Ferret (Italy - Switzerland)

A long climb from Rifugio Elena (2,062m) up to 2,537m, with some of the most sustained elevation gain on the TMB. Cold temperatures, strong winds, and snow possible early in the season. The descent into Switzerland is long and tiring.

You don't have to carry all the gear you need for your guided trek as we offer, for an extra charge, a bag transfer service. You will need a suitable rucksack to accommodate your daily clothing/equipment, food and drink and any other items you wish to have with you during the day. On ALL our treks some nights are spent in mountain refuge accommodation that have no vehicular access and so cannot be accessed by the baggage transfer team. On those days it is necessary to carry an overnight bag. See our Bag Transfer page for further information.

Breakfast:

This varies depending on accommodation. You can expect at least cereal, milk, break and jam and hot drinks. Our hotels on the treks offer a more substantial breakfast including yogurt, cheeses, cold meats, eggs and pastries.

Picnic lunch:

This is not included and you will need to purchase a picnic to carry with you each day. This is easily bought from local bakeries or supermarkets and when staying in more remote locations it can be ordered from the refuge on the night of arrival. Allow approx. 10 euros each day for your picnic. Make sure you take plenty with you and don’t rely on stopping for lunch en-route. Although on some days this will be possible it’s always good to have your own provisions in case the refuge or café is closed or busy.

Evening meal:

When on the trek, this is always provided and will consist of 3 courses, typically you will have soup or a salad for the starter, a meat or vegetarian option for the main course and a home-made dessert or cheese.

Some of the hotels offer a laundry service (e.g. the hotel in Courmayeur at the halfway point on the Tour du Mont Blanc). We recommend that you take clothing that can be washed by hand and dries quickly.

• Waterproof jacket and trousers

• Warm layers (fleece, down jacket)

Medical

Your own insurance is crucial.

If you are unsure of your insurance cover, please ask us before the trek, rather than at the time when you may require assistance.

Possessions

Equipment can easily be lost or left behind on a trek and Mont Blanc Treks cannot be held responsible for your private possessions. During transfers, bags are left for collection and again after delivery, in some relatively public places within the hotels we use. Please make sure possessions, bags and equipment are adequately insured and kept safe. Suggestions for trekking insurance companies that have been used by previous clients are:

Most TMB treks start in Les Houches (France) or Courmayeur (Italy). The nearest airports are:

Geneva (Switzerland) – The most common arrival point, with transfers available to Chamonix/Les Houches.

Turin or Milan (Italy) – Suitable for starting in Courmayeur.

Airport transfer can be booked online. See www.mountaindropoffs.com and by using our promotional code MBTCHX you will receive a discount off their flexi fare. The flex fare gives you peace of mind if your flight is delayed as they will transfer to the next available transfer unlike the supersaver which if missed, will be recharged. This would cost approx. 45€ per person each way. If you are a group of 4 or more, we can get preferential rates for you.
