On Tuesday January 27, 2026, around 7 p.m., a fire broke out in Courchevel 1850. The fire started in the attic of the five-star Grandes Alpes hotel. This hotel is located in Courchevel 1850, in Savoie. The next morning, Wednesday January 28, the blaze was not yet fully under control: the fire was spreading “under the roof,” difficult to reach. Authorities reported no civilian casualties, but four firefighters with minor injuries. Nearly 280 people were evacuated (guests, staff, and neighboring buildings), and an investigation will have to determine the origin of the fire.
A Winter Evening Turns Upside Down on La Croisette
In Courchevel 1850, winter has its routines: late-afternoon arrivals, hushed hallways, the smell of damp wood drying near the radiators. And then, on Tuesday, everything changed.
Around 7 p.m., the first sign came from above, where no one is ever looking. In the attic, the heat settled in, wrapped itself around the beams, found an air pocket. Soon, the roof was smoking.
Emergency services were alerted. The Savoie prefecture took charge of coordination, and SDIS deployed the first teams. In the resort, the news spread faster than the snowflakes.
Guests came down, some in ski gear, others in bathrobes, phones clutched tightly in hand. Staff guided, reassured, urged them onward. The priority was simple: get everyone out before the smoke reached the corridors.
Massive Evacuations, With No Civilian Casualties
The human toll, at this stage, comes down to one word authorities repeat cautiously: no civilians injured. That is the fixed point in a shifting night.
Inside the Grandes Alpes, then in the neighboring buildings, evacuations followed one after another. The numbers varied as counts were taken, amid the confusion of forgotten badges and rooms emptied in a hurry. Authorities put the total at around 280 people, sometimes reported as “more than 270” or “nearly 300” depending on successive updates.
The neighboring building, the Le Lana hotel, was evacuated as a precaution. The danger was not only the flames: it was the spread through connected roofs, the possible ignition via attics and technical passageways.
During the night, some evacuees were relocated to other hotels. The town set up emergency shelter solutions. This allowed those affected to find a roof over their heads and retrieve their belongings. They were thus able to get a little rest.
Under Slated Roofs, A Fire That Keeps Moving
What makes the fire so dangerous is not only its intensity: it is its geography.
In Courchevel 1850, large hotels and residences are intertwined. The buildings touch, echo one another, and sometimes share technical areas. Fire loves those passages.
The slate roof — those flat stones typical of the Alps — adds another layer of difficulty. Under the stone, there is insulation, metal materials, voids, cavities. Fire does not simply reveal itself: it moves, hides, returns.
The heavy snow makes everything harder. It weighs down structures, hides access points, and smothers smoke vents. To reach the flames, crews sometimes have to dismantle, saw, and strip away material. A slow, physical, dangerous fight.
Authorities mentioned a localized risk of collapse. That is the crews’ nightmare: working as close as possible to a weakened roof while keeping a safety margin.
Firefighters On Oxygen, With Cross-Department Reinforcements
The operation is an endurance test. Dense, opaque smoke requires frequent rotations. Teams sometimes work with supplemental oxygen to endure conditions that are otherwise unbreathable.
The response scaled up. Reinforcements came from Savoie, but also from Isère and Haute-Savoie. At peak response, as many as 145 firefighters and around 70 vehicles may have been mobilized.
In this kind of creeping fire, technology helps see what the eye cannot. Crews use thermal monitoring to locate hotspots. They use drones, in particular, to guide hose lines. They also check that an area thought to be extinguished is not still smoldering.
Four firefighters were slightly injured during the operation: injuries consistent with rooftop firefighting and smoke exposure (inhalation, impacts, sprains). Authorities stressed that nothing was serious, but it was enough to underscore the violence of a fire “under the roof.”
Tap Water Unsafe: Contamination Risk After Extinguishing
By morning, the crisis had taken a new form. An announcement came: drinking water had been made unsafe for consumption in the area. Indeed, an infiltration of firefighting foam had contaminated the network.
This detail says a lot about mountain communities. Here, networks are sometimes complex, layered, and sensitive to accidental backflow. When firefighting involves large volumes of water and additives, health precautions become immediate.
The instructions were simple and had to be repeated: do not drink tap water until the advisory is lifted. The town and operators organized temporary solutions, with bottled water distribution and information for lodging providers.
This consequence is a reminder that in a fire, not everything burns: some damage is invisible, yet it affects the daily lives of thousands of people — residents, seasonal workers, tourists.
An Investigation Announced, With The Cause Still Unknown
At this stage, the cause of the fire is not known. Authorities have announced a judicial investigation once the fire is fully out and the site can be accessed.
The gendarmerie is securing the perimeter. The goal is twofold: protect people and preserve the evidence useful to investigators.
In such situations, investigators examine what the fire leaves behind: the point of origin, paths of spread, technical failures, signs of overheating, ventilation equipment, or electrical systems. But as long as the attic remains unstable and hot, no one goes in.
Authorities are careful to remind everyone: hypotheses are only hypotheses. And in a resort, rumors can spread just as fast downhill.
Courchevel 1850, A Luxury Showcase Under Pressure
The fire strikes a symbol. Courchevel 1850 is not just an altitude figure: it is an image, an economy, a seasonal machine.
The resort, at the heart of the Three Valleys, lives to the rhythm of winter. Hotels, restaurants, shops, services: everything converges on welcoming and protecting an international clientele. When a fire rips through a roof, jobs, bookings, stays, and transfers all wobble.
The consequences will be measured in the coming days: how long the response lasts, access to affected areas, repairs, and the continuity of nearby activities. For neighboring establishments, the immediate issue is whether they can reopen, reassure guests, and rehouse them.
And there is the Alpine constraint, the one that makes safety harder than in the lowlands: cold, snow, access, altitude, intertwined buildings, heavy roofs.
Fire Safety In Resorts: The Challenge Of Connected Buildings
The Grandes Alpes fire raises a very concrete question: how do you fight when buildings are back-to-back, when roofs touch, when volumes are intertwined?
Crews then have to fight on two fronts: extinguish and prevent spread. That sometimes means removing cladding, creating openings, building water barriers, and keeping a constant watch on junction points.
Prefect Vanina Nicoli stressed the complex nature of the response. In this kind of fire, you do not easily “contain” it: you gain ground, lose ground, and come back.
The presence of multiple materials under the roof — stone, insulation, metal, wood — requires a finely tuned strategy. Too much water, and you add weight to already weakened structures. Too little, and embers spread into new spaces.
Thermal drones, continuous monitoring, shift rotations, and safety measures: all of this makes up the grammar of a long operation that can last hours, even days.
The Coming Days: Relocation, Cleanup, And Conditional Reopening
Once the fire is out, the work changes. Structures will need to be checked, areas secured, and any risk of reignition eliminated. In the attic, a hot spot can survive for a long time.
For evacuees, the urgency is more personal: finding belongings, papers, a medication left in a room, a coat. Reception teams handle these requests one by one, and that is often where the crisis becomes real: in small needs, quiet anxieties.
On the public health side, bringing the water network back into compliance will require testing, flushing, and confirmation. As long as there is doubt, caution is essential.
For the resort, finally, the issue is as much image as reality: showing that the evacuation worked, that interagency coordination held, and that safety remains a priority despite the unexpected.
What Is Known, And What Remains To Be Established
The facts are clear for now: a fire started Tuesday, January 27 in the attic of the Grandes Alpes. Then, spread under the roof and toward neighboring buildings occurred. The response was still ongoing on the morning of Wednesday, January 28. As a result, nearly 280 evacuees were reported, as well as four firefighters with minor injuries. In addition, tap water is temporarily unsafe.
The rest will come later: the cause, the precise timeline, any technical failure, the conditions of spread, and the true extent of the damage.
In Courchevel, snow covers the tracks quickly. But a fire leaves a memory: sirens, empty hallways, and that fire which, one evening, chose to run under the roofs.
