Tour Du Mont Blanc

While you can technically start the circuit anywhere, the traditional starting and ending point is Les Houches, a village just down the valley from the adventure capital of Chamonix, France.

Spend a day in Chamonix before your trek to pick up last-minute gear and acclimatize to the alpine air. Take the dizzying Aiguille du Midi cable car up to 3,842 meters for a terrifyingly close view of the Mont Blanc summit. The first day of the trek out of Les Houches immediately hits you with a steep ascent over the Col de Voza, testing your legs and introducing you to the massive scale of the Alps.

Around day three or four, you will cross the Col de la Seigne pass, leaving France and entering the Aosta Valley of Italy. The landscape abruptly shifts; the Italian side of Mont Blanc (Monte Bianco) is sheer, rocky, and far more imposing than the rounded French side.

The trail descends into the chic Italian mountain town of Courmayeur. This is the perfect halfway point to take a "zero day" (rest day). Trade your trail snacks for incredible Italian espresso, fresh pasta, and pizza. Many hikers mail a resupply box to their hotel in Courmayeur to swap out gear or pick up fresh clothes.

Crossing the border out of Italy, the W-Trek enters Switzerland. The scenic highlight of the Swiss sector is Champex-Lac (1,466 meters / 4,809 feet), a tranquil alpine lake village affectionately nicknamed "Little Canada" due to its dense spruce and pine forests, wooden chalets, and crystal-clear waters.

Trek along the peaceful Swiss farm meadows of Val Ferret, passing traditional wooden barns and stone farmhouses overflowing with bright pink geraniums. Spend a restful afternoon in Champex-Lac, renting a wooden rowboat to paddle across the calm, mirror-like lake or enjoying a fresh Swiss fondue in a lakeside café.

To complete the legendary Mont Blanc loop, head to Trient (1,300 meters), a quiet Swiss hamlet famous for its striking pink stone church and close proximity to the massive Trient Glacier. Trient serves as the launchpad for the final mountain crossing back into France.

Embark on the challenging climb up to the Col de Balme (2,191 meters). The border between Switzerland and France runs directly through the ridge of this high alpine pass. Stand at the stone border marker and look down over the entire Chamonix Valley, treated to a monumental, clear view of the massive Mont Blanc massif.

To ensure you complete the circuit safely and happily, keep these practical tips in mind:

• Book Refuges Months in Advance: The TMB is incredibly popular. You must book the mountain refuges (especially in France and Switzerland) 6 to 9 months in advance. Wild camping is strictly prohibited in most areas along the route.
• Pack Ultra-Light: Because you are sleeping in refuges that provide dinner, breakfast, and bedding, you do not need a tent, sleeping bag, or stove. Keep your pack weight under 8 kg (18 lbs) to save your knees on the punishing 1,000-meter descents.
• Respect the Alpine Weather: The hiking season is short (late June to early September). Even in July, you can encounter violent thunderstorms or snow on the high passes. Carry high-quality rain gear and always check the local meteorological reports before ascending.

The Tour du Mont Blanc is a rite of passage for hikers worldwide. It is physically demanding, but the reward of walking through three distinct alpine cultures in a single loop makes every blister worth it.
