Tour du Mont Blanc
Europe's iconic alpine trek circling the majestic Mont Blanc massif through France, Italy, and Switzerland
Destination Overview
The Tour du Mont Blanc (TMB) is one of the world's most famous and spectacular long-distance hiking routes. This approximately 170km (105 mile) circuit encircles the entire Mont Blanc massif, passing through three countries – France, Italy, and Switzerland – and offering unparalleled views of Mont Blanc (4,809m) and surrounding peaks.
The classic route crosses numerous high mountain passes, winds through alpine meadows bursting with wildflowers, descends into forested valleys, and connects picturesque mountain villages with distinct cultural flavors. Typically completed in 11 days, though variations from 7 to 14 days are common, the TMB combines challenging hiking with surprising comfort, as trekkers can stay in mountain refuges, small hotels, or campgrounds along the way.
When to Visit
The standard hiking season for the Tour du Mont Blanc runs from mid-June to mid-September. July and August offer the warmest weather and the most reliable access (all mountain passes are generally snow-free), but also bring the largest crowds and require booking accommodations months in advance. The shoulder periods (mid-June to early July and September) offer fewer crowds, beautiful wildflowers in early season, and autumn colors in September, though there may still be snow on higher passes in June, and some refuges begin closing in mid-September. Weather in the Alps can change rapidly in any season, with snow possible even in August at higher elevations.
Getting There
Most hikers begin the Tour du Mont Blanc in Les Houches or Chamonix, France. Geneva International Airport (Switzerland) is the closest major airport, located about 100km from Chamonix, with regular shuttle services making the 1-1.5 hour journey. Alternatively, hikers can reach Chamonix by train from Paris (via Saint-Gervais-les-Bains) or from various cities in Switzerland and Italy. The circular nature of the trek means you'll end where you started, simplifying transport logistics. While most hikers traditionally trek counterclockwise, either direction is possible.
Highlights
Col de la Seigne
This historic 2,516m mountain pass marks the border between France and Italy, offering breathtaking panoramic views of the southern side of the Mont Blanc massif. As you cross from one country to another, the landscape transforms dramatically, revealing the rugged Val Veny with its glaciers and towering peaks. The col has served as an important alpine crossing for centuries, used by local traders and pilgrims.
Lac Blanc
Perhaps the most photographed spot on the entire Tour du Mont Blanc, this stunning alpine lake sits at 2,352m above the Chamonix Valley. The still waters perfectly reflect Mont Blanc and the jagged Aiguilles Rouges (Red Peaks), creating a mirror image that captures the essence of Alpine beauty. The surrounding area is home to ibex and marmots, adding wildlife spotting opportunities to the incredible scenery.
Grand Col Ferret
Marking the border between Italy and Switzerland at 2,537m, this pass delivers spectacular views of Swiss Val Ferret and the Grand Combin massif. The descent into Switzerland reveals a landscape of perfectly maintained green pastures dotted with grazing cattle and traditional chalets, offering a striking contrast to the wilder terrain on the Italian side. The Swiss precision becomes immediately apparent as you cross this significant cultural boundary.
Things to Do
Classic 11-Day Trek
Complete the entire 170km circuit around Mont Blanc through France, Italy, and Switzerland over 11 days of challenging but rewarding hiking. This traditional approach allows time to acclimatize to the altitude, fully appreciate the changing landscapes and cultures, and enjoy the camaraderie that develops among hikers tackling this iconic route together.
Fast-Packing
Experience the TMB as a challenging 7-day trek for those with excellent fitness and limited time. This compressed itinerary covers the same route with longer daily distances (20-30km) and requires superior physical conditioning, but rewards with a sense of accomplishment and the full TMB experience in a condensed timeframe.
Alpinism & Glacier Experiences
Add mountaineering elements to your TMB experience with guided glacier excursions or summit attempts on accessible peaks along the route. Chamonix and Courmayeur offer opportunities to hire certified mountain guides for side adventures ranging from basic glacier walks with crampons to more technical climbs on peaks like Mont Blanc du Tacul.
Cultural Exploration
Immerse yourself in the distinct Alpine cultures of France, Italy, and Switzerland through their architecture, cuisine, and traditions. Each country offers a unique experience: French alpine farm cuisine, Italian hospitality and coffee culture, and Swiss precision and dairy specialties, creating a cultural journey alongside the physical one.
Where to Stay
Mountain Refuges (Refugios/Rifugios/Hüttes)
Mid-rangeThe classic TMB experience involves staying in mountain huts situated at strategic points along the route. These range from basic facilities with dormitory-style accommodations to more comfortable lodges with smaller rooms. Most offer half-board service (dinner and breakfast) and pack lunches. The social atmosphere of shared meals and dormitories creates lasting connections with fellow hikers from around the world.
€50-80 per night (half-board)
Alpine Villages & Town Accommodations
LuxuryThe TMB passes through several charming alpine villages and towns where hikers can find comfortable hotels and guesthouses offering private rooms, hot showers, and sometimes wellness facilities to soothe tired muscles. Notable stops include Chamonix and Les Contamines in France, Courmayeur in Italy, and Champex-Lac in Switzerland, providing welcome luxury interludes during the trek.
€80-200 per night
Camping Options
BudgetFor the more adventurous and budget-conscious, camping is possible at designated sites along much of the TMB. Some refuges offer camping spaces with access to facilities, while official campgrounds in valleys provide more amenities. This option requires carrying more gear but offers the most authentic connection with the alpine environment and significant cost savings.
€10-20 per tent
Travel Tips
Book Accommodations Early: Refuges and hotels along the route fill up months in advance, especially for July and August. Reserve your accommodations at least 6 months ahead, or consider using a booking service that specializes in the TMB.
Physical Preparation: The TMB involves approximately 10,000m of cumulative ascent and descent over its length. Prepare with regular hill training, carrying your planned pack weight, for at least 3 months before your trek. Focus on endurance and downhill strength, as descents can be particularly challenging.
Pack Efficiently: Weather in the Alps can change rapidly. Bring waterproof layers, warm clothing regardless of season, sun protection, and proper hiking boots with ankle support that are well broken-in. Keep your pack as light as possible while ensuring safety.
Currency Considerations: The route passes through both Euro (France and Italy) and Swiss Franc (Switzerland) territories. Carry some of each currency, though many places accept cards. Mountain refuges in remote locations may only accept cash.
Trail Variations: Numerous alternative high and low routes exist. Research options like the Grand Balcon Sud above Chamonix or the Mont de la Saxe ridge above Courmayeur for spectacular variant routes that can enhance your experience depending on weather and fitness.
