Le Brévent (2,525 m) is not the highest point on the Tour du Mont-Blanc. It is not the most remote, either. But it is the summit from which you see most clearly what you have just traveled. The entire massif unfolds across the valley, from the Aiguilles de Chamonix to the Dôme du Goûter, with Mont-Blanc dead center. After ten days of hiking around this mountain, you are finally standing face to face with it, barely 8 km away as the crow flies.
Mountain hiking guides, we consider this final stage the last real climb of the circuit. The ascent is honest and steep, the panorama more than repays the effort, and the descent to Les Houches (1,500 m of elevation loss, the longest on the TMB) tests your knees one last time. In this article, we cover the full route, the passage by Refuge de Bellachat, options for shortening the day, and a few stories about the first travelers who stumbled upon Chamonix.

The defining moment: reaching the summit of Le Brévent. Mont-Blanc fills the horizon, 8 km away as the crow flies. Below, the Chamonix valley traces a green ribbon 1,500 m lower. This is where Dr. Michel-Gabriel Paccard, in the 18th century, studied Mont-Blanc through a telescope to plan the route for the first ascent.
You leave the Refuge de la Flégère (1,877 m) heading southwest, in the opposite direction from the trail you followed the day before from Trè-le-Champ. The path traverses the Charlanon alpage along the hillside, with the Mont-Blanc massif in constant view on your left. You pass beneath the slopes of l'Index (2,595 m), then the route winds around several hollows, including the Combe de la Parsa, alternating between larch groves, rock slabs, and open pasture.
About 1h30 after setting out, you reach Planpraz (2,000 m), the intermediate station of the Le Brévent cable car. The building has a refreshment stand and restrooms. This is a decision point: you can ride the cable car down to Chamonix (in case of bad weather or fatigue), or continue hiking toward the summit of Le Brévent.
Along this stretch you will cross paths with day hikers who rode up from Chamonix by cable car, far more numerous than on the previous TMB sections. After the relative solitude of the Swiss Val Ferret or the pastures of Alp Bovine, the contrast is striking.
The climb from Planpraz to Le Brévent takes roughly 1h15. The trail passes through the Col du Brévent (2,368 m), marked by a cairn, then crosses a rocky spur equipped with two metal ladders (8 and 9 rungs) before reaching the summit (2,525 m). The passage is exposed but well secured. In rain or after a thunderstorm, the rungs and surrounding rock are slippery: exercise extra caution, and consider the cable car as an alternative. You can also take the second section of the cable car to ride directly to the summit from Planpraz.
From the top, the panorama stretches 360°. To the east, the entire Mont-Blanc range is laid out: the Aiguille du Midi (3,842 m), Mont-Blanc du Tacul (4,248 m), Mont Maudit (4,465 m), Mont-Blanc (4,809 m), Dôme du Goûter (4,304 m), and Aiguille de Bionnassay (4,052 m). Below, Chamonix looks tiny. To the west, you can see the Aiguilles Rouges massif, Lac Blanc (where some hikers passed the day before), and on very clear days, the Jura mountains in the distance.
It was from Le Brévent that Dr. Michel-Gabriel Paccard studied Mont-Blanc to identify a route to the summit. On August 8, 1786, together with Jacques Balmat, he completed the first ascent. The city of Chamonix was transformed. The initiative had come from Genevan naturalist Horace-Bénédict de Saussure, who had been observing the mountain since 1760 and offered a reward to anyone who found a way to the top. Balmat claimed credit for the ascent for many years. It took the research of historian T. Graham Brown, in the 20th century, to restore Paccard's place as the true first ascensionist.
From the summit of Le Brévent, the trail descends first through a rocky slope, then into alpine pasture. In 1h to 1h15, you reach the Refuge de Bellachat (2,152 m), perched on a grassy shelf with a plunging view over the Chamonix valley and the Glacier des Bossons directly opposite.
Refuge de Bellachat is the last place to stop before the long final descent. The warden serves simple, generous food. It is an ideal spot for lunch, or for spending one last night at altitude if you want to split the stage in two.
This is the most demanding part of the day. From Bellachat (2,152 m) to Les Houches (977 m), roughly 1,200 m of elevation loss remain over 7 km. Trekking poles are not a luxury here.
The trail leaves the refuge across a steep grassy slope, drops 300 m in tight switchbacks, then enters the Réserve naturelle de Carlaveyron around 1,800 m. The reserve was created in 1991 to protect 598 hectares of old-growth forest and wetlands. Its existence was not a given: a plan to extend the ski lifts toward the Montagne de Carlaveyron had been considered before being abandoned in favor of the reserve.
The descent continues through forest (larches, then spruce) to a junction for the Parc animalier de Merlet (1,500 m), where ibex, chamois, and marmots roam in semi-freedom with Mont-Blanc as a backdrop. The park is visible from the trail; a visit adds about 1h to the day. Past Merlet, the trail joins a wider forest track. You reach the P3 parking area (1,370 m), the first road access since the refuge.
The final 400 m of descent wind through forest to the platform of the Christ-Roi statue (1,200 m), erected in 1934 at the initiative of Abbé Claude-Marie Delassiat, parish priest of Les Houches. The Arve valley spreads out below. The last stretch crosses the hamlet of Le Coupeau before reaching the Les Houches train station (980 m). The TMB is complete.
Arriving in Les Houches, you are following in the footsteps of earlier explorers without knowing it. In June 1741, two young English aristocrats, William Windham and Richard Pococke, left Geneva with an armed escort to explore the Chamonix valley. At the time, the place was a dead end at the bottom of a mule track, virtually unknown to the outside world. Windham described the "Mer de Glace" (he coined the name) and the Chamonix needles in a letter that caused a sensation in London. A few decades later, the writer and canon Marc-Théodore Bourrit, based in Geneva, published between 1773 and 1801 several editions describing the glaciers of Chamonix, with engravings widely circulated in European scientific and literary circles. Alpine tourism was born, and Chamonix would become its capital.
For those who do not want the TMB to end too quickly, a lesser-known variant extends the final day. From Refuge de Bellachat, instead of descending directly to Les Houches, the trail follows the ridge westward over the Aiguillette du Brévent (2,310 m) and the Pointe de Lapaz (2,313 m), then continues to the Aiguillette des Houches before descending via the Chalets de Chailloux (1,923 m) and Plan de la Cry (1,440 m). Allow 5 to 6h from Bellachat, with +200 m and -1,400 m. It is a ridge route with continuous views of the Mont-Blanc range, away from the crowded trails. It reaches Les Houches from the west side, less steep than the direct descent.
Stage 11 is long (6h30 to 8h) and the descent is grueling. Several options let you adapt:
Water is available at Refuge de la Flégère at the start, at the Planpraz refreshment stand, at Refuge de Bellachat, then in Les Houches at the finish. The descent between Bellachat and Les Houches is long with no water source: carry at least 1.5 liters from Bellachat in summer.
The summit of Le Brévent is exposed to wind and thunderstorms. If the forecast is uncertain, aim to reach the top early in the day (summer storms typically build in early afternoon). The descent faces southwest: in midsummer, heat in the forest can be oppressive in the afternoon. Leaving La Flégère before 7:30 AM is recommended.
The climb to Le Brévent is sustained but technically straightforward. The descent is the real challenge of this stage: 1,860 m of elevation loss puts serious strain on your quads and joints. Trekking poles are essential. If your knees are giving you trouble, consider the cable car for at least part of the descent.
From the Les Houches train station, the Mont-Blanc Express connects to Chamonix (10 min) and Saint-Gervais-Le-Fayet (15 min), where TGV connections serve Paris, Lyon, and Geneva. The Tramway du Mont-Blanc, departing from Saint-Gervais-Le-Fayet and climbing to the Nid d'Aigle, also stops at the Col de Voza station (the one you passed on Stage 1). Local buses fill in the gaps. If your car is parked in Les Houches, the loop is closed. If you left it in Chamonix or Saint-Gervais, the train brings you back in minutes.
Yes, by taking the cable car from Planpraz. But the summit of Le Brévent is often cited as the finest viewpoint on the entire TMB. Missing it means finishing the trek without the summit panorama. If your legs allow it, hike up.
It is the longest descent on the TMB. On your knees and joints, it is demanding, especially after ten days of hiking. Trekking poles, a steady pace, and frequent breaks make it manageable. The forest provides shade, which helps in summer.
It is doable for very fit hikers. The combination of Trè-le-Champ, La Flégère, Le Brévent, then Les Houches amounts to roughly 23 km with 1,750 m of gain and 2,200 m of loss. Seven-day itineraries sometimes do it. In our TMB in 7 days, we organize this section with accumulated fatigue in mind.
Les Houches and Chamonix have everything you need to recover: restaurants, brewpubs, outdoor shops, and the Saint-Gervais thermal baths are a 20-minute train ride away. If you are heading home by public transit, the Saint-Gervais-Le-Fayet station connects to the TGV network and Geneva airport.
The Tour du Mont-Blanc ends in Les Houches, where it began. You set down your pack, look up at the mountain one last time, and know you have walked the full circle. Three countries, eleven stages, 170 km, roughly ten passes.
Stage 1 of the TMB, the one that took you out of Les Houches eleven days ago (or seven, or five), is the start of another circuit if the urge returns. To place this final stage in the context of the full route, the complete Tour du Mont-Blanc article details all 11 stages, the variants, and all the logistics. And if you want to experience the TMB in comfort with a guide who knows every pass, the TMB in 7 days with Altimood condenses the best of the circuit into one week.
You have just come from Stage 10, Trè-le-Champ to Refuge de la Flégère along the Grand Balcon Sud.
