The Wild Side
The Tour des Combins begins at the Gran San Bernardo, a historically rich, windswept pass in the heart of the Pennine Alps. From there this three day trans-alpine loop alternates between lush valleys full of streams, marmots and majestic coniferous forests to more rugged and rocky mountainsides, where glaciers paint spectacular views of most impressive 4000 meter alpine peaks.

Despite being one of the most scenic trans-Alps routes, Tour des Combins is one of the least known. Lodged between the Mont Blanc massif and the Matterhorn, the TdC circumnavigates the slopes of the Combins Range (4,314m) starting from the Gran San Bernardo Pass (2,473m), on the border between Italy and Switzerland. After the pass the route crosses the Gran San Bernardo valley on the Italian side using panoramic singletrack. For a short stretch it overlaps the ancient Via Francigena, a medieval 1800km pilgrim trail from Canterbury UK to Rome. The route continues on singletrack trails and doubletrack roads between the beautiful valleys of the Valle d’Aosta, the Menouve, and the Conca di By. From there, working counterclockwise, the TDC pushes into alpine meadows and coniferous woods, dominated by the snowy peaks of Mont Vèlan, Gelè, and the Grand Combin.

The TdC has a few challenging hike-a-bikes, such as that leading to the Fenêtre de Durand (2,797 m), a border crossing to enter Switzerland and the highest point of the route. Here, in the most remote area on the TdC, the landscape changes radically. Waterfalls, glacial rivers and sharp peaks offer epic high mountain scenery. However, the difficult push to reach the Fenêtre de Durand pass is rewarded by a magnificent singletrack descent towards the turquoise lake of Mauvoisin with another amazing backdrop.

After passing the town of Fionnay the Tour Du Combins climbs among typical alpine meadows, first on a steep but rideable gravel road and then on singletrack to reach the Col de Mille, another alpine pass at an altitude of 2,472m. From here the view is extraordinary with the eastern side of the Mont Blanc Massif as a background for the descent that leads to the small village of Bourg Saint Pierre. The TdC continues through Val d’Entremont to reach the border crossing with Italy, where stands the outline of the Grand Saint Bernard Hospice, which is home to the famous St Bernard dog (see highlights).

Difficulty: This route has been assigned an 7.5 due to the high altitude gain and a couple of very challenging hike-a-bikes. The first one you meet, on the mountain above the village of Saint-Rhémy-en-Bosses, is very steep and forces you to either shoulder the bike or climb step by step with the bike in front of you. There are also two other short stretches both in the Conca di By. The first is a very narrow passage between the rocks where you have to pass the bike keeping it vertically on the rear wheel, the second is an easy stretch of via ferrata where you have to proceed with caution due to the weight of the loaded bikes.

Note that this loop can be easily connected to the most famous Tour du Mont Blanc to create an incredible and challenging bikepacking route.

  • The Hospice du Grand Saint Bernard was built by Saint Bernard around 1050 A.D. to provide assistance pilgrims and travelers who ventured over that fearful pass. From the mid-seventeenth century, the monks of the Hospice began to use big mountain dogs to rescue travelers or pilgrims who had been lost in the snow or fog, or those who were caught in an avalanche. Thus was born the myth of the Saint Bernard rescue dog.
  • 60 meters of ancient Roman road dug directly into the rock between 41-54 A.D., commissioned by Emperor Claudius. You will ride this section after passing the statue of San Bernardo on the hill with the same name.
  • The astonishing view of the Mont Blanc massif from the Col du Mille.
  • Fantastic singletrack descent from the Fenêtre de Durand pass to the Drance du Bagnes river. Incredibly fun in the first part, however it becomes steep and technical in the latter half.
  • Epic views from Fenêtre de Durand towards the glacier d’Otemma.
  • Old Swiss customs house in Bourg Saint Pierre dating back to 1901. Cigarette smugglers are depicted on the front side.
  • A trail bike such as a plus-hardtail is recommended for this route. A suspension fork is highly recommended as there are several technical descents.
  • The route is only rideable from mid-June to mid-September, when all the passes are free from snow. Because of the abundant snowfall at high altitude, even the paved road to the San Bernardo pass remains closed for 8 months a year. However, as Alexander mentioned in the comments, “… refrain from doing this trip until July. Last winter for instance saw little snow, yet around mid-June Fenetre de Durand on the Swiss side was full of snow with strong water streams hidden.”
  • Carry mountain weather clothing and gear with you and be prepared as snow and sudden temperature drops are all but rare on the high passes… even in the summer months.
  • We recommend to do the Tour du Combins counterclockwise.
  • Most of the route is marked with a yellow diamond with black outline, which sometimes bears the letters “TDC” in the center.
  • In Switzerland wild camping is not generally encouraged, but is tolerated. However, according to the Swiss Apline Club, camping above treeline is accepted. So set up late, strike early, be discreet, and leave it as you found it.
  • If necessary, on the Col de Mille there is the Cabanne de Mille refuge, where you can eat and sleep.
  • There is an official camping spot in Foret des Melezes.
  • Water is never a problem: it’s plenty of streams and rivers along the route, and fountains with drinking water are frequent in the villages.
  • If necessary, you can refuel in a market in the small village of Lourtier (Switzerland).
