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

The morning at the Rifugio Elisabetta has a quality all its own. Mont Blanc's south face is still wrapped in pre-dawn shadow, Lac Combal lies motionless below, and the walking ahead, the fourth stage of the Tour du Mont-Blanc, is mostly downhill through Val Veni, the Italian corridor that alpinists have long called "the Himalayan face of Mont Blanc."

Stage 4 trades dramatic col crossings for something more immersive. Here, the spectacle is lateral: you walk at the base of the massif rather than above it. Italy's longest glacier, the Miage, spreads ten kilometres of debris-covered ice just above the trail. The Brenva face looms to the northeast. And at the end of the valley, Courmayeur is waiting, espresso, stone fountains, warm Italian hospitality, and a proper meal that doesn't cost a fortune.

We, the mountain guides Altimood, think of this stage as one of the TMB's most satisfying transitions. You move from the world of moraines and high-altitude silence into a proper Italian mountain town, and the shift feels earned. Many of the Canadian hikers we've guided through this circuit note how differently Courmayeur hits after days on the trail, the town has a life and character that genuinely rewards arriving on foot rather than by car. Flying into Geneva and crossing through the Mont Blanc Tunnel, you've already had a sense of the cultural layering; Stage 4 makes it physical.

This guide covers the full itinerary from Rifugio Elisabetta to Courmayeur: terrain data, the Mont Favre variant, the Miage glacier's geology, the history of the Brenva face, accommodation, and practical advice for 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 drops from the Rifugio Elisabetta 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 catches the south face of Mont Blanc in a fleeting, imperfect reflection. It lasts only a few minutes before the sun warms the valley and a breeze stirs.

The lake occupies the bottom of a glacial basin edged with wetlands. It's a fragile ecosystem: the peat bogs shelter rare plant species, and the trail follows the right bank to protect the most sensitive areas. About fifteen minutes of flat walking through here, a genuine rarity on the TMB.

The Miage Glacier: Italy's Longest Glacier

Nothing about the Miage glacier looks like what most people picture when they hear the word "glacier." No gleaming seracs, no open crevasses: this ten-kilometre river of ice is completely covered in rocky debris, giving it the appearance 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 rock blanket plays a counterintuitive role: it insulates the ice from solar radiation and slows melting, which is why the Miage extends to a lower elevation than its "clean" neighbours. The ice is very much 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 a closer look, an unmarked lateral path climbs the moraine and opens up a view of the glacier's chaotic surface, proceed with care, as there are no waymarks.

The Allée Blanche: Walking Beneath the South Face

The Val Veni carries another name on historical maps: the Allée Blanche. This fifteen-kilometre glacial corridor, oriented east-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 kilometres to the south.

Walking through the Allée Blanche, the south face of Mont Blanc stays with you the entire length of the corridor. The contrast with the north side, the face visible from Chamonix, is striking: darker, more vertical, rawer. 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 to the invention of the word "moraine" in its modern geological sense.

The Brenva Face

Look northeast and the Brenva face commands the horizon. 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 struck the opposite slope. Tragically, two skiers in the valley below lost their lives, a reminder that this side of Mont Blanc remains powerfully unstable. The scar from that collapse is still visible from the trail 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 cowbells carry across the hillside. Val Veni is an active summer alpage, and herds of Valdostan cattle move up here each season.

The classic TMB route climbs to Col Chécrouit (1,956 m) along a balcony path with sweeping views down the valley and over the Miage glacier. It's a pleasant stretch, steady grade, open sightlines.

Refuge de Maison-Vieille (1,956 m)

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

Mont Favre Variant (2,433 m)

For hikers who want to add elevation and earn a wider view, the Mont Favre variant branches off the main trail after Lac Combal and climbs to the rounded summit of Mont Favre (2,433 m). 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 rejoins the classic route at Col Chécrouit.

This variant adds roughly two hours and 400 meters of extra elevation gain. It's worth it in clear conditions, in fog, the Mont Favre summit adds effort without adding much to the experience. When we guide the TMB and conditions cooperate, this is the route we choose every time: the view from the summit onto the Brenva face is one of the circuit's best moments on the Italian side.

The Descent into Courmayeur

From Col Chécrouit, the path down to Courmayeur winds through larches on a well-graded forest track. The gradient is steady, with no technical sections, but your knees will notice the 700 meters of descent over roughly five kilometres. Get the trekking poles out if they aren't already.

The trail emerges at the first chalets of Dolonne, a neighbourhood of Courmayeur, before crossing the Doire Baltée and entering the town centre. The shift from mountain track to pedestrian street is immediate, a few steps and you're surrounded by boutiques, gelato shops, and café terraces.

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

Courmayeur is not simply a stage town, it's a proper mountain resort with real character. A historic destination in the Aosta Valley, it has hosted Mont Blanc's first explorers, the golden-age alpinists, and generations of skiers. The name likely derives from the Latin curia major, the great court, a reference to its medieval administrative role.

For the TMB hiker, Courmayeur represents a genuine turning point. It's the first real encounter with a town since Les Houches (or Les Contamines, depending on your threshold). 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 time to assess your gear, take care of any blisters, and enjoy a long hot shower. Of all the towns on the TMB, Courmayeur is the one where an unscheduled rest day feels most justified when the program allows.

The Skyway Monte Bianco

From Courmayeur, the Skyway Monte Bianco cable car climbs in two sections to the Pointe Helbronner (3,466 m). 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 experience the high-mountain environment without a rope or crampons.

It's a half-day detour with no connection to the hiking itself, but it puts the scale of what you're walking around into perspective in a compelling way. The ticket (around €50 round-trip) and summer crowds are the main considerations. Our advice: go early in the morning, well before the tour buses.

Accommodation for Stage 4

In Courmayeur

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

• Central hotels: several establishments welcome TMB hikers, with luggage storage and laundry options. Expect €80–150 per night for a double room in high season. Advance booking is recommended 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 divide 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 litres 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 enclosed by high ridges, can get stifling in midsummer. Setting off early from the Rifugio Elisabetta lets you cover the upper section in cooler morning conditions. If a storm develops, 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. A good moment to pick up some Fontina cheese and Valdostan charcuterie.

Logistics and Access

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

Frequently Asked Questions, TMB Stage 4

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

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

Is the Mont Favre variant worth the extra effort?

In clear weather, yes, definitely. The summit of Mont Favre (2,433 m) gives one of the best views of the Brenva face and the Italian side of Mont Blanc. In fog or poor visibility, the classic valley trail is already beautiful and will serve your legs better for the days ahead.

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

Yes. Seasonal shuttle buses serve Val Veni between Courmayeur and Lac Combal in summer. Schedules vary from year to year. It's a reasonable option if you're fatigued, dealing with an injury, or want to keep time for exploring Courmayeur. Check with the Courmayeur tourist office or the Rifugio Elisabetta for current schedules.

What should I do in Courmayeur when I arrive?

Courmayeur deserves more than an overnight. If your vacation schedule allows, a rest day at the halfway point of the TMB 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 streets, or simply a terrace and a plate of polenta concia.

Is the Skyway Monte Bianco worth it during the TMB?

It's an entirely different experience from hiking. Going up to 3,466 m by cable car gives you an aerial view of the massif you're circling that's genuinely hard to match any other way. The panorama takes in Mont Blanc, the Grandes Jorasses, the distant Matterhorn, and the Grand Paradis. Budget half a day and around €50. If you have one clear day in Courmayeur, it's worth making the trip.

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 continuing to the Rifugio Bertone on the Stage 5 trail. In high season, booking at least a month ahead is the smart approach 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 details all 11 stages, the variants, the ideal seasons, and full logistics. If you'd like to experience the TMB with carefully chosen accommodation and a dedicated guide, the TMB in 7 days with Altimood condenses the best of the circuit into a single week, a good fit for those with limited vacation time.

If you've come from Stage 3 from Les Chapieux, you already know the south face from the col. This stage brings you all the way to its foot.
