|---|---|---|
| Total distance | ~170 km | autourdumontblanc.com |

| Technical skills | None required on standard route | Cicerone |
| Permit | None — but refuge booking IS the de facto permit | montourdumontblanc.com |
The distance discrepancy in the literature (165-170 km depending on the source) arises from variant routes and how town-centre waypoints are measured. The honest number is approximately 170 km.
11-stage breakdown (counter-clockwise)
The classic itinerary starts and ends at Les Houches. Counter-clockwise is traditional; clockwise is equally common and avoids afternoon sun on the Italian stages.
| Stage | From | To | Dist. | Ascent | Descent | Key feature |
|---|---|---|---|---|---|---|
| 1 | Les Houches (1,007 m) | Les Contamines-Montjoie | 16 km | 646 m | 633 m | Gentle opener through the Montjoie valley |
| 2 | Les Contamines | Les Chapieux | 18 km | 1,316 m | 929 m | Col du Bonhomme (2,329 m), Col de la Croix du Bonhomme (2,483 m) |
| 3 | Les Chapieux | Rifugio Elisabetta | 15 km | 1,004 m | 258 m | Col de la Seigne (2,516 m) — France/Italy border |
| 4 | Rifugio Elisabetta | Courmayeur (1,224 m) | 18 km | 460 m | 1,560 m | Long descent into Val Veny. Courmayeur is the Italian hub. |
| 5 | Courmayeur | Rifugio Bonatti (2,025 m) | 12 km | 860 m | 101 m | Mont de la Saxe ridge; Grandes Jorasses panorama |
| 6 | Rifugio Bonatti | La Fouly (1,593 m) | 20 km | 895 m | 1,410 m | Grand Col Ferret (2,537 m) — Italy/Switzerland border |
| 7 | La Fouly | Champex-Lac (1,466 m) | 15 km | 420 m | 565 m | Valley walk through Swiss Val Ferret |
| 8 | Champex-Lac | Col de la Forclaz (1,526 m) | 16 km | 742 m | 682 m | Bovine route or Fenetre d'Arpette variant (2,665 m) |
| 9 | Col de la Forclaz | Tre-le-Champ (1,417 m) | 13 km | 1,069 m | 1,178 m | Re-enter France via Col de Balme (2,191 m) |
| 10 | Tre-le-Champ | Refuge La Flegere (1,877 m) | 8 km | 733 m | 257 m | Grand Balcon Sud; Lac Blanc spur |
| 11 | Refuge La Flegere | Les Houches | 17 km | 772 m | 1,546 m | Brevent traverse; final descent |

Compression options
Not everyone has 11 days. Here are the realistic compression strategies:
7-8 days: Combine stages 1+2, 6+7, and/or 10+11. This produces 25-30 km days with 1,500+ m of ascent. Requires good fitness and early starts.
Classic 10 days: Split the longest stages by adding intermediate refuges — Refuge de la Croix du Bonhomme (between stages 2-3) and Rifugio Elena (between stages 5-6).
Comfort 11+ days: Add rest days in Courmayeur and Champex-Lac. Both have proper restaurants, shops, and hotels.
Clockwise vs. counter-clockwise
Counter-clockwise (traditional): The Italian section comes early, Switzerland is in the middle, and the final stages traverse the Aiguilles Rouges with continuous views of the massif. Most TMB literature describes this direction.
Clockwise: Fewer people walking in this direction means less trail congestion. The Italian stages come later, so the food improves as the legs tire. The Col de la Seigne descent into Italy is walked as an ascent — steeper but with views opening ahead.
Neither direction is objectively better. If you are booking late and peak-season refuges are full in one direction, try the other — different stages fill on different dates.
Refuge booking
This is the single most important logistics decision on the TMB.
The booking system
The TMB's primary booking platform is montourdumontblanc.com. This centralized system covers 50+ affiliated shelters across all three countries.
Key facts for 2026:
- Bookings opened October 15, 2025 (the portal had technical issues on launch day)
- Peak season (mid-July to mid-August): book 6-9 months ahead. Popular refuges sell out within days of the portal opening.
- Shoulder season (late June, September): 2-3 months ahead is usually sufficient.
- Modifications allowed up to 48 hours before arrival.
- Cancellation: free up to 7 days before arrival (travel credits); policies vary by refuge — confirm at booking.
Refuges NOT on the portal
These must be booked directly by email or phone:
- Rifugio Bonatti (Stage 5) — one of the most popular refuges on the circuit
- Rifugio Elisabetta (Stage 3)
- Refuge du Lac Blanc (Stage 10 spur)
- Refuge Miage

Why booking IS the permit
The TMB has no formal hiking permit. But wild camping is prohibited or heavily restricted in most sections:
| Country | Wild camping rule |
|---|---|
| France | Bivouac allowed above treeline between 7 PM and 9 AM (one-night max). Some reserves prohibit it entirely. |
| Italy | Rules vary by commune. Val Ferret generally prohibits camping. |
| Switzerland | Bivouac tolerated above treeline in non-protected areas. Cantonal rules apply. |
Without confirmed refuge reservations, completing the TMB in peak season is effectively impossible. The booking is the access control.
Half-board pricing by country
Half-board (dinner + breakfast + dormitory bed) is the standard booking unit at mountain refuges. Prices vary substantially by which side of the border you are on.
| Country | Half-board range | Dorm-only range | Notes |
|---|---|---|---|
| France | EUR 75-100 | EUR 30-45 | Paid showers common (EUR 2-4). Wine is extra. |
| Italy | EUR 60-85 | EUR 25-40 | Best food of the three countries. Showers usually included. |
| Switzerland | CHF 100-130 (~EUR 100-130) | CHF 50-70 | Everything costs more. |
Source: recency.md; 2025/2026 published pricing. Hut prices are rising 5-10% per year due to energy and staffing costs.
The CHF shock: crossing into Switzerland
The TMB crosses into Switzerland at Grand Col Ferret (Stage 6) and exits at Col de Balme (Stage 9). This covers stages 6 through 8 — roughly three days.
| Item | France/Italy | Switzerland | Multiplier |
|---|---|---|---|
| Dorm bed + half-board | EUR 60-100 | CHF 100-130 | 1.3-2.0x |
| Beer (50cl draft) | EUR 5-7 | CHF 8-12 | ~1.7x |
| Simple lunch | EUR 12-18 | CHF 20-30 | ~1.7x |
Swiss huts increasingly accept cards, but carry CHF cash as backup. Champex-Lac has an ATM. La Fouly does not (confirm locally). Budget an extra EUR 50-80 total for the Swiss stages compared to equivalent French stages. See full cost guide.
Variants worth considering
Fenetre d'Arpette (Stage 8 alternative)
The standard Bovine route from Champex-Lac to Col de la Forclaz follows a relatively gentle contour. The Fenetre d'Arpette variant (2,665 m) is the highest point on any TMB variation — a steep scree col with panoramic views of the Trient Glacier. Physically harder, but avoids the road section through Trient. Check conditions at La Chamoniarde — snow can persist into early July on north-facing approaches.
Col des Fours (Stage 2 alternative)
At 2,665 m, the Col des Fours adds a high-altitude detour above the standard Col du Bonhomme route. Views of the Mont Blanc massif from the east.
Lac Blanc spur (Stage 10)
Not a variant so much as a mandatory detour — the trail to Lac Blanc (2,352 m) departs from the Stage 10 path and offers arguably the finest reflection of Mont Blanc and the Aiguilles in the Alps. The Refuge du Lac Blanc operates July-September. See day hikes from Chamonix.
Gear
The TMB is not technical. All paths are non-glacial.
| Item | Required? | Notes |
|---|---|---|
| Crampons / ice axe / rope | No | Not needed on any standard TMB path |
| Trekking poles | Recommended | Stage 4 descends 1,560 m; Stage 11 descends 1,546 m |
| Rain gear (full waterproof) | Essential | Afternoon storms frequent July-August |
| Warm layers | Essential | Passes at 2,200-2,665 m; near-freezing in bad weather, even in July |
| Sleeping bag liner | Required | All refuges provide blankets but require a personal liner (silk or synthetic) |
| Headlamp | Essential | Early starts, refuge after-dark protocol |
| Sun protection | Essential | High UV at 2,000+ m; hat, sunscreen, sunglasses mandatory |
For the Fenetre d'Arpette variant in early July: microspikes may be needed on north-facing snowfields. No crampons in normal conditions mid-July through September. Source: Cicerone; La Chamoniarde.
Lift shortcuts
Bad weather or tired legs? Cable cars can shortcut or bypass several stages.
| Cable car | Elevation | TMB stage | Use case |
|---|---|---|---|
| Le Brevent | 2,525 m | Stage 11 | Skip the final descent to Les Houches |
| La Flegere | 1,877 m | Stage 10 | Skip the ascent from the valley floor |
| Balme-Charamillon | ~2,270 m | Stage 9 | Shortcut the Col de Balme descent |
The TMB in context
The TMB is not "Europe's greatest trek" by physical challenge (the GR 20 in Corsica, with 12,000 m of gain over 180 km, is harder) or by remoteness (the Walker's Haute Route from Chamonix to Zermatt is more isolated). It is Europe's greatest trek by historical density per kilometre — Roman trade routes, Enlightenment science, Victorian grand tourism, the professionalization of mountain guiding, three-country diplomacy, and real-time glacial retreat, all packed into a 170 km loop.
