For the next several years the Mont Blanc Tunnel will be closed from September to December for scheduled maintenance works. This makes the journey from Chamonix to Courmayeur impractical for a short 4-day itinerary, as the alternate driving route would require a very long road detour around Mont Blanc via Martigny and over the Great St. Bernard Pass. For the month of September groups will instead hike the sections of the Tour du Mont Blanc trail from Champex Lac in Switzerland all the way to the end in Chamonix, thereby avoiding the long drive to the Italian side of Mont Blanc, whilst still including some of the major highlights and a full TMB hiking experience. A significant benefit of this alternate route is September groups will be able to visit the beautiful Lac Blanc on day 4, high up on the Aiguilles Rouges, with some of the finest panoramic views of the Mont Blanc massif found anywhere on the entire TMB circuit.
Day 1 - Orsieres to Champex
After meeting your hosts at either Geneva Airport or Les Houches, you'll be driven to Orsieres on the Swiss side of the Mont Blanc massif. From there you’ll hike up the trail up to the lakeside village of Champex, where you’ll join up with the main TMB trail. A short walk further and you’ll arrive at your first mountain refuge of the trip, Gite Bon Abri, in time for a hearty dinner with your fellow hikers. The Gite Bon Abri is located on the edge of Champex, in a quiet spot right off the trail, and is popular with cheese-lovers for its signature fondue.
Hiking: 3hrs - 6.5km - 480m up - 92m down
Day 2 - Champex to Trient
Today you’ll hike up and over the mountains via the classic Bovine route to Trient. This winding forest trail leads you up past mountain streams to the Bovine Refuge and the high alpages, where you are rewarded with spectacular views of the Rhone Valley. Make sure to stop for a slice of the best cake the region has to offer! From the top of Bovine you'll descend down the wooded trail to the Col de la Forclaz. Shortly after you'll be able to enjoy deep valley views from a boardwalk, looking down on Trient and its famous pink church. From there it's a short section down to the village and your well earned rest for the night at La Grande Ourse, a larger property than the night before with hostel style rooms, boot/drying room and wifi.
Hiking: 6-7hrs - 16km - 780m up - 890m down
Day 3 - Trient to Vallorcine
It’s time to hike across the border into France, and get your first views of the Chamonix Valley. Hiking up out of Trient you’ll ascend switchback trails through pine forest, past clear mountain streams and up into the high alpine. Reaching the Col de Balme (2190m), you’ll be rewarded with an expansive vista down the Chamonix Valley towards Mont Blanc and the Aiguille du Midi. You’ll then traverse round to another excellent view point, L'Aiguillettes des Posettes, and take the long descent down to Vallorcine. Tonight you’ll stay at Le Gite Mermoud, with its friendly local owner and traditional Savoyan-style offering the typical Mont-Blanc experience.
Hiking: 6-7hrs - 14km - 950m up - 920m down
Day 4 - Vallorcine to Chamonix
Today begins with gentle climb out of Vallorcine up to the Col des Montets, you’ll then turn right and ascend the trail to Tete aux Vents and onto the Grand Balcon Sud, perhaps the most scenic of all the high alpine paths with panoramic mountain views not surpassed anywhere in the world. From Aiguille du Tour at the eastern end, to the Aiguille du Chardonnet, L’Aiguille Verte and Les Drus, to the towering Aiguille du Midi and the white summit of Mont Blanc in the west, with all their mighty glaciers in between, the full expanse of the Mont Blanc massif is on show. A short detour from the main TMB trail will take you up past Lac des Cheserys to Lac Blanc, where the jagged mountain skyline is reflected in the cold waters of this alpine lake. From there your hike is almost complete, head down the trail to La Flegere Station, rest your legs and enjoy the views from the cable car as you glide back down to the valley floor, finishing off with a stroll into the centre of Chamonix. Usually the hike is finished around 16:00 in central Chamonix. There is just time for a quick celebration drink with the group before your shared bus transfer departs at around 17:00 for Geneva Airport, for those heading off that day.
Hiking: 6hrs - 12km - 1050m up - 500m down
