3 Valleys

You can ski for a week in Les 3 Vallées and never take the same run twice. Covering 10,500 hectares across the Tarentaise and Maurienne valleys, it is the largest fully interconnected ski area on the planet. The scale is difficult to grasp until you are actually there – 600 kilometres of groomed runs linked entirely by lifts and pistes. You can start your morning on the tree-lined slopes of Courchevel and end up on the high-altitude glaciers of Val Thorens by lunch, without ever taking your skis off. The network connects seven distinct resorts. You get everything from the traditional Savoyard feel of Saint-Martin-de-Belleville to the concrete convenience of Les Menuires. Because 85% of the skiable area sits above 1,800 metres, the snow holds up well into spring. If you want to cover serious distance and explore multiple valleys in a single trip, this is the place to do it.

The domain spreads across three main parallel valleys in the Tarentaise, plus a fourth valley in the Maurienne. From east to west, the Saint-Bon valley houses Courchevel and La Tania. The central Allues valley is home to Méribel and Brides-les-Bains. The western Belleville valley contains Saint-Martin-de-Belleville, Les Menuires, and Val Thorens. Finally, the Maurienne valley to the south provides access via Orelle.

These valleys connect through a network of high-speed gondolas and chairlifts crossing the dividing ridges. You navigate between them by ascending to key ridge points – like Saulire between Courchevel and Méribel, or Mont de la Chambre between Les Menuires and Val Thorens – and skiing down the other side. The transitions are usually seamless. Instead of flat polling tracks, you get long, rewarding descents into the next valley. The layout is surprisingly logical once you get your bearings. The ridges run north to south, meaning you generally ski east or west to change valleys. This geography also means you can chase the sun throughout the day, skiing the east-facing slopes of the Allues valley in the morning and the west-facing slopes of the Belleville valley in the afternoon.

Terrain, lifts & piste mix

The 600 kilometres of runs break down into 334 individual pistes: 53 green, 136 blue, 108 red, and 37 black. The distribution skews heavily towards intermediate cruisers. It is a paradise for skiers who want to cover long distances comfortably. You will find wide, rolling blues that seem to go on forever, particularly above Méribel and Courchevel 1650. The red runs offer a step up in pitch, often dropping straight down the fall line from the major ridges.

The lift infrastructure is incredibly efficient. The operating companies spend heavily on high-capacity, fast lifts to clear bottlenecks, even during the busy February half-term weeks. The 161 lifts can move over 260,000 skiers per hour. You rarely wait long, even at the major intersection points. The older, slower chairlifts are mostly gone, replaced by six-seater and eight-seater expresses, many with heated seats and weather bubbles.

Off the groomed runs, the freeride potential is massive. Areas like the Vallon du Lou in the Belleville valley or the couloirs around the Saulire offer lift-accessed terrain that rivals dedicated off-piste destinations. The sheer size of the area means hiring a local guide is a smart move if you want to explore beyond the markers safely. They know where the snow holds best and how to navigate the complex avalanche terrain that sits between the marked pistes.

One pass, one domain

The “Forfait Les 3 Vallées” is the single lift pass that unlocks the entire 600-kilometre network. You can buy individual valley passes – like a Courchevel-only or Méribel-only ticket – but the full area pass is the standard choice. It allows unrestricted movement across all ridges and valleys, removing the headache of checking whether your pass covers the lift you are about to board.

The pass covers every lift in the network, from the low-altitude gondolas in Brides-les-Bains and Orelle to the highest cable cars in Val Thorens. It also gets you into the snowparks, boardercross courses, and beginner zones. The ticketing system relies on hands-free smartcards that scan automatically at the lift gates, keeping the queues moving. If you plan to ski for six days, the full area pass usually pays for itself if you cross into a neighbouring valley just two or three times.

Resorts in the domain

The domain comprises several distinct bases, each with its own character and altitude. You can choose your base depending on your budget, your skiing style, and what you want to do after the lifts close.

Courchevel

Actually a collection of several villages at different altitudes (1850, 1650, 1550, and 1300), this easternmost valley is famous for immaculately groomed pistes, luxury chalets, and high-end dining. The skiing offers a good mix of sheltered woodland runs lower down and wide, open bowls higher up. Courchevel 1650 (Moriond) tends to catch the afternoon sun and offers some of the best intermediate cruising in the entire domain.

Méribel

Situated in the central valley, Méribel is the geographical heart of the domain. Its chalet-style architecture and busy après-ski scene make it a favourite among British skiers. The central location gives you the quickest access to both the Courchevel and Belleville valleys. You can start your day heading east or west depending on the weather and your mood.

Val Thorens

At 2,300 metres, Val Thorens is the highest ski resort in Europe. It sits in a spectacular high-alpine bowl at the head of the Belleville valley, offering snow-sure conditions from late November to early May. The terrain here is open, dramatic, and largely above the tree line. It is the place to go when the snow is thin lower down, though it can be exposed when the weather turns bad.

Les Menuires

Located below Val Thorens in the Belleville valley, Les Menuires is a purpose-built resort that prioritises ski-in/ski-out convenience and affordability. It gives you excellent access to a huge variety of sunny, west-facing slopes and the challenging La Masse sector. The architecture is famously functional, but the skiing access is hard to beat.

Saint-Martin-de-Belleville

A traditional Savoyard village lower down the Belleville valley, Saint-Martin retains its historic charm with a beautiful church and narrow streets. It connects to the wider domain via a fast gondola and chairlift, making it a quieter, more authentic base. It has gained a reputation as a gastronomic hub, with several excellent restaurants both in the village and on the slopes above.

Brides-les-Bains

A historic spa town located down in the valley floor at 600 metres, Brides-les-Bains links to Méribel via the Olympe gondola. It provides a more budget-friendly accommodation option and is famous for its thermal baths. The gondola ride takes about 25 minutes, but the savings on accommodation and the access to a real, working French town appeal to many visitors.

Orelle

Situated in the Maurienne valley, Orelle is not a traditional resort but a small village with a gondola (the 3 Vallées Express) providing direct access to the Val Thorens ski area. It is a popular day-trip access point for skiers driving up from the south, allowing them to bypass the winding roads of the Tarentaise valley entirely.

Planning a week on the mountain

With 600 kilometres to explore, a week here requires some strategy. A popular approach is to spend a day or two exploring your local valley, getting a feel for the home slopes before venturing further afield. You do not want to spend your first day rushing to make lift connections if you are still finding your ski legs.

For full-day excursions, skiers often plan “safaris” to the furthest points of the domain. If you are based in Courchevel, you might spend a day navigating across to Val Thorens and back. These long-distance days mean you need to watch the time and the lift closing schedules. Missing the last lift back over the ridge usually results in an expensive taxi ride around the valley floor. The lift operators are strict about closing times, and the ski patrol sweeps the ridges promptly.

Intermediate skiers can easily cross the entire domain using only blue and red runs. The signposting is generally excellent, with clear indications of the routes back to the main valleys. You will see large signs pointing to “Courchevel via Saulire” or “Val Thorens via Mont de la Chambre,” making it difficult to get completely lost. Still, carrying a piste map or using the official app is essential for planning your route and avoiding the steeper black runs if you prefer to cruise.

When to visit & snow reliability

The season runs from early December to late April. Val Thorens opens earlier in late November and closes in early May. The snow reliability is exceptional, mostly because 85% of the skiable terrain sits above 1,800 metres. When lower resorts in the Alps are struggling with rain or slush, the upper reaches of Les 3 Vallées usually have cold, dry snow.

Even in leaner snow years, the area’s massive snowmaking infrastructure keeps the main arterial links between the valleys open. They have over 2,300 snow cannons covering more than half the pistes. The snowmaking teams work through the night to ensure the busy connecting runs remain skiable, even if natural snowfall has been scarce.

January and February offer the coldest temperatures and the best powder conditions, though the February half-term is predictably busy. If you visit in February, the trick is to ski the edges of the domain – like Courchevel 1650 or the La Masse sector in Les Menuires – while the crowds stick to the central ridges. March brings longer days and reliable bases. April is favoured for sunny, warmer skiing and lively afternoon après-ski on the terraces, though the snow on the lower, south-facing slopes can become heavy by mid-afternoon.

Beyond skiing

While the sheer volume of skiing is the main draw, the region offers plenty off the slopes. The area has an impressive concentration of Michelin-starred restaurants, particularly in Courchevel and Saint-Martin-de-Belleville, alongside hundreds of traditional mountain huts. You can find everything from simple tartiflette to high-end tasting menus.

Non-skiers can use the extensive pedestrian lift pass network to meet friends for lunch at high altitude. Other activities include massive toboggan runs in Val Thorens and Courchevel, dog sledding, snowshoeing, and cross-country skiing trails in the lower valleys. The toboggan run in Val Thorens, starting from the Péclet glacier, is particularly famous, offering a six-kilometre descent that takes nearly an hour to complete.

In the summer, the snow melts to reveal a vast playground for mountain biking, hiking, and trail running. Many of the main lifts operate to transport bikes and pedestrians up the peaks. The area has invested heavily in downhill mountain bike trails, creating a summer network that mirrors the winter ski pistes, with graded trails for different abilities.

How the linked domain grew

The concept of linking these separate valleys was first envisioned in the 1920s, but development only really took off after the Second World War. Courchevel was the first to be developed in 1946, followed by Méribel. The original vision was to create a massive, interconnected ski area that would rival anything in the world, driven by the French government’s push to develop winter tourism.

The true realization of the interconnected domain happened in the 1970s. Val Thorens was established in 1972, pushing the ski area to unprecedented altitudes. By 1973, the lift connections between the three main valleys were completed, allowing skiers to cross the ridges seamlessly. It was a massive engineering feat, requiring the construction of lifts in harsh, high-alpine environments.

Since then, the operating companies have focused on upgrading the lift network, replacing older, slower lifts with high-speed, high-capacity alternatives to handle the growing crowds. The focus has shifted from expanding the skiable area to improving the quality of the experience, with investments in snowmaking, lift speed, and slope grooming. The result is a domain that feels remarkably modern, despite its long history.

Who it suits best

Les 3 Vallées is arguably the ultimate destination for mileage-hungry intermediate and advanced skiers who want to ski a different route every day of their holiday. The seamless lift connections and vast scale make it a paradise for those who view skiing as a journey rather than just lapping the same slopes. You can set out in the morning with a destination in mind and spend the whole day travelling.

It is also highly suitable for mixed-ability groups. Almost every challenging red or black run has a gentler blue or green alternative nearby, allowing groups to split up and meet at the bottom of the lift. Families appreciate the dedicated beginner zones and the extensive network of ski schools across all the resorts.

However, the sheer size and sometimes bustling nature of the main arterial pistes might feel overwhelming for absolute beginners or those seeking a quiet, intimate, small-scale mountain experience. If you just want a single, quiet slope to practice your turns, you might find the constant movement of skiers across the domain distracting. But for those who want variety, scale, and reliable snow, it is hard to beat.
