TMB Stage 4: Descent Through Val Veni, from Rifugio Elisabetta to Courmayeur

Step out onto the terrace of the Rifugio Elisabetta at dawn, and the south face of Mont Blanc is still in shadow. The hanging glaciers glow faintly, Lac Combal sleeps below, and the day ahead promises something different from everything before it: a long descent through Val Veni, the side of the massif that alpinists call "the Himalayan face of Mont Blanc."

Stage 4 of the Tour du Mont-Blanc doesn't deliver the dramatic col crossings of earlier days. The spectacle here is lateral, you walk at the foot of the massif, not above it. Italy's longest glacier, the Miage, unrolls ten kilometers of rocky debris just above the trail. The Brenva face, one of the most imposing walls in the Alps, blocks the horizon to the northeast. And at the valley's end, Courmayeur is waiting, espresso, sun-drenched terraces, gelato shops, and that unmistakable Italian ease that hits you harder after three days on the trail.

We, the mountain guides Altimood, love this stage for what it delivers beyond the hiking: a genuine change of world. You trade high-altitude silence for a lively Italian town, swap the crunch of moraine for the hum of a café terrace, and realize that the TMB isn't just a trek, it's a journey through three distinct cultures. That shift feels especially vivid when you've flown to Geneva and driven up through the tunnel, and suddenly you're ordering polenta at a sidewalk restaurant in the Aosta Valley.

This article breaks down the route from Rifugio Elisabetta to Courmayeur: the Mont Favre variant, terrain data, the geology of the Miage glacier, the history of the Brenva face, accommodation options, and everything you need to know before arriving in town.

Stage 4 at a Glance

Note on stage divisions: in 7-day itineraries, this stage is often merged with the end of Stage 3, heading directly from Col de la Seigne to Courmayeur. The route described here starts from the Rifugio Elisabetta, the most common breakdown in the classic 11-stage version. Some guidebooks split this section further by adding an overnight at Maison-Vieille (Col Chécrouit), creating a shorter day.

Lac Combal and the Start of Val Veni

The trail leaves the Rifugio Elisabetta and drops toward Lac Combal, a lake that the Miage glacier's alluvial deposits fill in a little more each year. On a calm morning, the still surface mirrors the south face of Mont Blanc in an imperfect, fleeting reflection. It lasts only a few minutes before the sun warms the valley and the breeze picks up.

The lake sits in the bottom of a glacial basin edged with wetlands. The ecosystem is fragile: the peat bogs shelter rare plant species, and the trail hugs the right bank to avoid the most sensitive zones. You get about fifteen minutes of flat walking here, a genuine luxury on the TMB.

The Miage Glacier: Italy's Longest Glacier

Nothing about the Miage glacier looks like a glacier at first glance. No sparkling seracs, no gaping crevasses: this ten-kilometer river of ice is completely buried under rocky debris, giving it the look of a vast, slowly shifting boulder field. It is the longest glacier on the Italian face of Mont Blanc and one of the largest debris-covered glaciers in the Alps.

That rocky blanket plays a counterintuitive role: it insulates the ice from solar radiation and slows down melting, which is why the Miage descends to a lower elevation than its "clean" neighbors. But the ice is absolutely there, beneath the stones, and it makes itself known. Surface collapses create temporary lakes on the glacier, and sudden floods have shaped Val Veni's history more than once.

From the TMB trail, you follow the glacier's left bank without ever setting foot on it. Information panels along the way explain the glacial dynamics. For hikers who want to get closer, an unmarked lateral trail climbs the lateral moraine and opens up a view of the glacier's chaotic surface, take care, as there are no waymarks.

The Allée Blanche: Walking at the Foot of the South Face

The Val Veni has an older name on historical maps: the Allée Blanche. This fifteen-kilometer glacial corridor, oriented east to west, connects Col de la Seigne to Courmayeur. It has been one of the Alps' main transit routes since antiquity: the Romans used it to reach Gaul via the Col du Petit Saint-Bernard, a few kilometers to the south.

Walking through the Allée Blanche, the south face of Mont Blanc towers over you for the full length of the corridor. The contrast with the north side, the face you see from Chamonix, is striking: darker, more vertical, more raw. In 1774, the scientist Horace-Bénédict de Saussure explored this face with guide Jean-Laurent Jordaney and became the first to describe Val Veni's moraines scientifically, contributing directly to the invention of the word "moraine" in its modern geological sense.

The Brenva Face

Look northeast and the Brenva face commands the view. Standing 1,500 meters tall, it is a mix of rock, ice and hanging seracs, one of the great Alpine walls. It was first climbed in 1865 by Adolphus Warburton Moore, Frank Walker, Horace Walker and their guide Jakob Anderegg, a feat that opened the era of serious ice climbing in the Alps.

The Brenva is also known for its collapses. In January 1997, an entire section of the face broke away, sending two million cubic meters of rock and ice into Val Veni. The shockwave crossed the valley and hit the opposite slope. Tragically, two skiers in the valley below lost their lives, a reminder that this side of Mont Blanc remains a powerfully unstable mountain. From the trail, the scar from that collapse is still visible in dry conditions.

The Descent to Col Chécrouit and Maison-Vieille

After the flat section at Combal, the trail descends gradually into the valley. The landscape shifts: moraines give way to pastures, larches begin to appear, and you start hearing cowbells. Val Veni is an active summer alpage, and herds of Valdostan cattle move up here every season.

The classic TMB trail climbs to Col Chécrouit (1,956 m) along a balcony path with sweeping views down the valley and over the Miage glacier. It's an enjoyable stretch, steady grade, heads-up walking.

Refuge de Maison-Vieille (1,956 m)

At Col Chécrouit, the Refuge de Maison-Vieille is a solid resupply stop. The terrace faces Mont Blanc directly and serves what is easily one of the best Italian coffees on the entire TMB. Hikers who want to split the stage can sleep here; those pushing to Courmayeur still have about 700 meters of descent ahead.

Mont Favre Variant (2,433 m)

For hikers looking to add elevation and earn a bigger view, the Mont Favre variant leaves the main trail after Lac Combal and climbs to the rounded summit of Mont Favre (2,433 m / 7,982 ft). The panorama from the top takes in the Brenva face, the full Miage glacier, and the entire Italian chain of the Mont Blanc massif. The descent reconnects with the classic trail at Col Chécrouit.

This variant adds roughly two hours and 400 meters of extra elevation gain. It's worth it in clear weather, in fog, the Mont Favre summit offers nothing beyond what the valley trail already gives you, with extra effort. When we guide the TMB and conditions are good, this is the variant we take without hesitation: the view from that summit onto the Brenva face is one of the standout moments on the Italian side of the circuit.

The Descent into Courmayeur

From Col Chécrouit, the trail down to Courmayeur follows a well-graded forest path that winds through larches. The slope is steady, with no technical sections, but your knees will know about it: 700 meters of descent over roughly five kilometers. Now is the time to break out the trekking poles if you haven't already.

The trail emerges at the first chalets of Dolonne, a neighborhood of Courmayeur, before crossing the Doire Baltée and entering the town center. The transition from mountain trail to pedestrian street is immediate, a few paces, and you're in the middle of boutiques, gelato shops, and café terraces.

Courmayeur (1,224 m): The Halfway Point of the TMB

Courmayeur is not just a trail stop, it's a full-fledged mountain town. A historic resort in the Aosta Valley, it has hosted Mont Blanc's first explorers, the golden-age alpinists, and generations of skiers. The name likely comes from the Latin curia major, the great court, a nod to its medieval administrative role.

For the TMB hiker, Courmayeur marks a turning point. It's the first real contact with civilization since Les Houches (or Les Contamines, depending on your standards). There's an ATM, a pharmacy, a laundromat, a supermarket, and restaurants where polenta costs less than a soft drink at a mountain hut.

It's also the right moment to audit your gear, deal with any blisters, and take a proper hot shower. Of all the towns on the TMB, Courmayeur is the one where a rest day is most happily spent when the schedule allows.

The Skyway Monte Bianco

From Courmayeur, the Skyway Monte Bianco cable car climbs in two sections to the Pointe Helbronner (3,466 m / 11,371 ft). The rotating cabin delivers a 360-degree view of the Mont Blanc massif, the Grandes Jorasses, the Matterhorn, and the Grand Paradis. At the top, a panoramic terrace and an ice cave let you touch the high-mountain world without a rope or crampons.

It's a half-day detour with nothing to do with hiking, but it gives you an aerial perspective on the massif you're circling on foot that's genuinely hard to match. The ticket (around €50 round-trip) and summer crowds are the main drawbacks. Our advice: go early in the morning, before the tour buses arrive.

Accommodation for Stage 4

In Courmayeur

Courmayeur offers a wide range of accommodation, from camping to four-star hotels. The most practical options for TMB hikers:

• Central hotels: several properties welcome TMB hikers, with luggage storage and laundry options. Expect €80–150 per night for a double room in high season. Book ahead for July and August.
• Hostel / gîte: the Gîte Le Randonneur du Mont Blanc, in Val Veni, is a more budget-friendly option.
• Camping: Camping Val Veni sits at the edge of Courmayeur toward Val Veni, reachable on foot from the trail.

Along the Route

• Refuge de Maison-Vieille (1,956 m, Col Chécrouit): for those who want to split the stage. Spectacular views, classic Italian refuge atmosphere.

Practical Tips for TMB Stage 4

Water on the Route

Water is available at the start (Rifugio Elisabetta) and at the Refuge de Maison-Vieille. Between the two, sources are scarce in midsummer. Carry 1.5 to 2 liters from the start. In Courmayeur, public fountains provide fresh drinking water throughout town.

Weather and Conditions

This stage is mostly downhill on a well-marked trail. The main risk is heat: Val Veni, oriented east-west and hemmed in by high ridges, can get stifling in midsummer. Starting early from the Rifugio Elisabetta lets you cover the upper section in the cool of the morning. If a thunderstorm moves in, the Refuge de Maison-Vieille offers shelter at the halfway point.

Supplies

The last resupply before Courmayeur is the Refuge de Maison-Vieille. In Courmayeur, several supermarkets and grocery stores let you stock up for the stages ahead on the Italian side. This is the moment to pick up some Fontina cheese and Valdostan charcuterie.

Logistics and Access

Courmayeur is connected by regular bus service from Aosta and the Mont Blanc Tunnel. If you need to leave the TMB or require medical attention, the nearest hospital is in Aosta (around 45 minutes by bus). Seasonal shuttles run up Val Veni to Lac Combal in summer, useful if injury or fatigue forces an early exit.

Frequently Asked Questions, TMB Stage 4

How long does it take to walk from Rifugio Elisabetta to Courmayeur?

Allow 5h30 to 7h of walking, depending on your pace and stops. The stage is predominantly downhill (1,450 m of descent versus 480 m of gain), which taxes your knees more than your lungs. Add roughly two hours for the Mont Favre variant.

Is the Mont Favre variant worth it?

In clear weather, absolutely. The summit of Mont Favre (2,433 m) gives one of the finest views of the Brenva face and the Italian side of the Mont Blanc massif. In fog or bad weather, stick to the classic valley trail, it's already beautiful, and you'll save your legs for the stages ahead.

Can I take a bus through Val Veni to shorten the stage?

Yes. Seasonal shuttle buses run through Val Veni between Courmayeur and Lac Combal in summer. Schedules vary from year to year. It's a legitimate option if you're tired, nursing an injury, or want to save time for exploring Courmayeur. Check with the Courmayeur tourist office or the Rifugio Elisabetta for current times.

What should I do in Courmayeur when I arrive?

Courmayeur deserves more than an overnight stop. If your schedule allows, a rest day mid-circuit is genuinely worthwhile. Beyond rest: the Skyway Monte Bianco (Pointe Helbronner, 3,466 m), the Pré-Saint-Didier thermal baths (5 km away, accessible by bus), a walk through the old town's cobbled lanes, or simply a terrace where you can work through a plate of polenta concia and a glass of local Fontina.

Is the Skyway Monte Bianco worth it during the TMB?

It's a different experience from hiking. Going up to 3,466 m by cable car gives you an aerial view of the massif you're circling on foot that's hard to replicate any other way. The panorama sweeps across Mont Blanc, the Grandes Jorasses, the Matterhorn in the distance, and the Grand Paradis. Budget half a day and around €50. If you have one day in Courmayeur and the sky is clear, it's worth it.

What if the hotels in Courmayeur are fully booked?

Alternatives include Camping Val Veni (at the edge of town), the Refuge de Maison-Vieille at Col Chécrouit (above, at 1,956 m), or pushing on toward the Rifugio Bertone on the Stage 5 trail. In high season, booking at least a month ahead is smart for Courmayeur.

What's Next on the TMB

Courmayeur is the gateway to the Italian Val Ferret. The next stage climbs toward the Rifugio Bonatti, one of the best-positioned refuges on the entire circuit, facing the Grandes Jorasses and the Dent du Géant. The variant along the Mont de la Saxe ridge delivers one of the finest viewpoints in the Alps.

To see how this stage fits into the full circuit, the complete Tour du Mont-Blanc guide covers all 11 stages, the variants, the ideal seasons, and full logistics. If you want to hike the TMB with hand-picked accommodation and a dedicated guide, the TMB in 7 days with Altimood condenses the best of the circuit into one week.

If you're coming from Stage 3 from Les Chapieux, you already know what the south face of Mont Blanc looks like from the col. This stage brings you right to its foot.
