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 Hôtel des Grandes Alpes. This hotel is located in Courchevel 1850, in Savoie. The next morning, Wednesday January 28, the blaze was not fully under control: the fire was progressing “under the roof,” hard to reach. Authorities reported no civilian casualties, but four firefighters slightly injured. Nearly 280 people were evacuated (guests, staff and nearby buildings), and an investigation will need to determine the cause of the fire.
A Winter Evening Shifts On The Croisette
In Courchevel 1850, winter has its routines: arrivals in the late afternoon, hushed hallways, the smell of damp wood being dried near radiators. And then, that Tuesday, a rupture.
Around 7 p.m., the first signal came from above, where no one ever looks. In the attic, heat settled, wrapped around the rafters, found a draft. Soon the roof was smoking.
Rescue services were alerted. The prefecture of Savoie took charge of coordination, the SDIS deployed the first teams. In the resort, the news spread faster than the snowfall.
Guests came downstairs, some in ski gear, others in robes, phones clutched in hand. Staff guided, reassured, urged. The priority was simple: get everyone out before the smoke reached the corridors.
Massive Evacuations, No Civilian Victims
The human toll, at this stage, comes down to a word authorities repeat cautiously: no civilian injured. That is the fixed point of a restless night.
Within the grounds of the Grandes Alpes, then in neighboring buildings, evacuations followed one after another. Numbers fluctuated amid the confusion of forgotten keycards and hastily emptied rooms. Authorities reported a total around 280 people, sometimes stated as “more than 270” or “nearly 300” depending on successive counts.
The neighboring building, Hôtel Le Lana, was evacuated as a precaution. The risk was not only the flame: it was the spread via contiguous roofs, possible ignition through attics and service passages.
During the night, some evacuees were rehoused in other establishments. The municipality set up emergency reception solutions. This allowed those affected to find shelter and belongings. They could thus get a bit of calm.
Under Lauze Roofs, A Running Fire
What makes the fire so fearsome is not only its intensity: it is its geography.
In Courchevel 1850, large hotels and residences are interlocked. Volumes touch, respond to one another, sometimes share technical areas. Fire likes those passages.
The roof, made of lauze — those flat stones typical of the Alps — adds difficulty. Under the stone there is insulation, metal materials, voids, cavities. The fire does not give itself up: it moves, it hides, it returns.
The thick snow complicates everything. It burdens structures, hides access points, stifles smoke vents. To reach the flames, crews sometimes have to dismantle, saw, strip. A slow, physical, dangerous fight.
Authorities mentioned a localized risk of collapse. That is the teams’ dread: working close to a weakened roof while keeping a margin of safety.
Firefighters Under Oxygen, Interdepartmental Reinforcements
The operation is a test of endurance. The smoke, dense and opaque, forces frequent rotations. Teams sometimes work with oxygen support to hold up in unbreathable conditions.
The deployment ramped up. Reinforcements came from Savoie, but also from Isère and Haute‑Savoie. Up to 145 firefighters and around 70 vehicles could be mobilized at the peak.
On this type of creeping fire, technology helps see what the eye cannot. Rescuers used thermal surveillance to locate hot spots. They notably employed drones to guide hoses. They also checked that an extinguished area was not smoldering.
Four firefighters were slightly injured during operations: injuries consistent with rooftop engagement and smoke (inhalation, impacts, sprains). Authorities stressed: nothing serious, but enough to recall the violence of a “under‑roof” fire.
Tap Water Unsafe: Risk Of Contamination After Extinguishing
By morning, the crisis changed shape. An announcement came: drinking water was declared unsafe in the area. Indeed, an infiltration of firefighting foam contaminated the network.
This detail says much about the mountains. Here, networks are sometimes complex, tiered, sensitive to accidental backflow. When firefighting uses volumes of water and additives, sanitary vigilance becomes immediate.
The instructions are simple and must be repeated: do not drink tap water until the situation is cleared. The municipality and managers organized temporary solutions, with bottled water distribution and information to hosts.
This consequence is a reminder that in a fire, not everything burns: some damages are invisible, but affect the daily lives of thousands — residents, seasonal workers, tourists.
An Investigation Announced, Origin Still Unknown
At this stage, the origin of the fire is not known. Authorities announced a judicial investigation once the fire is completely extinguished and the site accessible.
The gendarmerie secures the perimeter. The objective is twofold: protect people and preserve elements useful to investigations.
In these situations, the inquiry attacks what the fire leaves behind: a starting point, paths, technical anomalies, signs of overheating, ventilation or electrical equipment. But as long as the attics remain unstable and hot, entry is prohibited.
Authorities take care to remind: hypotheses are only hypotheses. And in a resort, rumors can spread easily.
Courchevel 1850, Showcase Of Luxury And Territory Under Constraint
The fire hits a symbol. Courchevel 1850 is not just an altitude: it’s 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 securing an international clientele. When a fire ravages a roof, jobs, bookings, stays, and transfers are shaken.
Consequences will be measured in the coming days: duration of the operation, access to areas, restoration, continuity of nearby activities. For neighboring establishments the issue is immediate: resume or not, reassure, rehouse.
And there is the alpine constraint, which makes safety harder than on flatland: cold, snow, access, altitude, interlocked buildings, heavy roofs.
Fire Safety In Resorts: The Challenge Of Adjoined Buildings
The fire at the Grandes Alpes raises a very concrete question: how to fight when buildings are buttressed, when roofs touch, when volumes intermix?
Rescue teams must wage a two‑front battle: extinguish and prevent spread. That sometimes means removing cladding, creating openings, establishing water barriers, and relentlessly monitoring junction points.
Prefect Vanina Nicoli stressed the complex nature of the operation. In this type of fire, you don’t easily “contain”: you gain meters, lose some, and return.
The presence of multiple materials under the roof — stone, insulation, metal, wood — requires a precise strategy. Too much water and you overload already weakened structures. Too little and embers reach new volumes.
Thermal drones, continuous surveillance, reliefs, securings: all that composes the grammar of a long operation, which can last hours or even days.
The Coming Days: Rehousing, Remediation, Conditional Resumption
Once the fire is out, the work changes nature. Structures will need inspection, zones secured, any risk of rekindling eliminated. In the attic, an ember can smolder for a long time.
For evacuees, the urgency is more personal: recovering belongings, papers, a medication left in a room, a coat. Reception units handle these requests one by one, and often that’s where the crisis is measured: in small needs, quiet anxieties.
On the health front, returning the water network to compliance will require checks, purges, confirmations. As long as doubt remains, caution prevails.
For the resort, finally, the stake is image as much as reality: show that the evacuation worked, that interservice coordination held, 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, a 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 slightly injured. In addition, tap water is temporarily unsafe.
The rest will come later: the origin, the precise timeline, any technical failure, the conditions of spread, the actual extent of damage.
In Courchevel, snow quickly covers tracks. But a fire leaves a memory: the sirens, the empty corridors, and that fire which, one evening, chose to run under the roofs.
