On Tuesday January 27, 2026, around 7:00 PM, a fire broke out in Courchevel 1850. The blaze 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 fire was not completely under control: the blaze was progressing “under the roof,” difficult to reach. Authorities reported no civilian casualties, but four firefighters slightly injured. Nearly 280 people were evacuated (guests, staff, and neighboring buildings), and an investigation will determine the origin of the fire.
A Winter Evening Turns on the Croisette
In Courchevel 1850, winter has its routines: arrivals in the late afternoon, hushed corridors, the smell of damp wood drying near radiators. And then, that Tuesday, the break.
Around 7:00 PM, the first signal came from above, where people never look. In the attic, heat set in, wrapped around the rafters, found a pocket of air. 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 flakes.
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 spread into the circulation areas.
Massive Evacuations, No Civilian Victims
The human toll, for now, comes down to a word authorities repeat cautiously: no civilian injured. That is the fixed point in a restless night.
Inside the Grandes Alpes, then in neighboring buildings, evacuations followed one another. Numbers changed as counts were updated amid forgotten keycards and hastily emptied rooms. Authorities mentioned a total around 280 people, sometimes reported as “more than 270” or “nearly 300” depending on successive tallies.
The neighboring building, Hôtel Le Lana, was evacuated as a precaution. The risk was not only the flames: it was propagation through continuous roofs, possible ignition via attics and technical corridors.
During the night, some evacuees were rehoused in other establishments. The municipality set up emergency reception solutions. That allowed those affected to find shelter and belongings. They could thus have a bit of calm.
Under Slate Roofs, a Fire That Runs
What makes the fire so fearsome is not just its intensity: it’s its geography.
In Courchevel 1850, large hotels and residences interlock. 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 elements, voids, cavities. The fire doesn’t announce itself: it moves, hides, returns.
The thick snow complicated everything. It weighs down structures, masks access points, stifles smoke outlets. To reach the flames, crews sometimes had to dismantle, saw, strip. A slow, physical, dangerous struggle.
Authorities mentioned a localized risk of collapse. That is the teams’ fear: working close to a weakened roof while keeping a safety margin.
Firefighters on Oxygen, Inter-Departmental Reinforcements
The operation was an endurance test. Dense, opaque smoke forced frequent rotations. Teams sometimes worked with supplemental oxygen to cope with unbreathable conditions.
The deployment grew. Reinforcements came from Savoie, but also from Isère and Haute-Savoie. Up to 145 firefighters and about 70 vehicles could be mobilized at peak.
On this type of creeping fire, technology helps see what the eye cannot. Rescuers used thermal surveillance to spot hot spots. They notably used drones to guide the hoses. They also checked that an extinguished area was not still smoldering.
Four firefighters were slightly injured during operations: injuries compatible with working on roofs and in smoke (inhalation, impacts, sprains). Authorities stressed: nothing serious, but enough to recall the violence of a fire “under the roof.”
Tap Water Unsafe: Risk of Contamination After Extinguishing
By morning, the crisis changed form. An announcement followed: 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 backflows. When extinguishing uses volumes of water and additives, sanitary vigilance becomes immediate.
Instructions were simple and must be repeated: do not drink tap water until the situation is resolved. The municipality and managers organized temporary solutions, distributing bottled water and informing accommodation providers.
This consequence reminds that in a fire, not everything burns: some damages are invisible, yet 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 as soon as the blaze is fully extinguished and the premises accessible.
The gendarmerie secured the perimeter. The goal is twofold: protect people and preserve elements useful for investigations.
In such situations, the inquiry focuses on what the fire leaves behind: a point of origin, pathways, technical anomalies, signs of overheating, ventilation or electrical equipment. But as long as the attics remain unstable and hot, no entry is made.
Authorities took care to remind: hypotheses remain only hypotheses. And in a resort, rumors can quickly gain traction.
Courchevel 1850, Showcase of Luxury and Territory Under Constraint
The fire struck 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: all converge on welcoming and securing an international clientele. When a roof is ravaged, jobs, bookings, stays, and transfers wobble.
Consequences will be measured in the days ahead: duration of the intervention, access to zones, restoration, continuity of nearby activities. For neighboring establishments, the immediate issue is whether to reopen, to reassure, to rehouse.
And there is the alpine constraint, which makes safety harder than on the plain: cold, snow, access, altitude, interlocked buildings, heavy roofs.
Fire Safety in Resorts: The Challenge of Adjoined Buildings
The Grandes Alpes fire raises a very concrete question: how to fight when buildings are buttressed, when roofs touch, when volumes intermix?
Rescuers must fight on two fronts: extinguish and prevent propagation. That sometimes means removing cladding, creating openings, establishing water barriers, and relentlessly monitoring junction points.
Prefect Vanina Nicoli stressed the complex nature of the intervention. In this type of fire, one does not “contain” easily: you gain meters, lose some, and come back.
The presence of multiple materials under the roof—stone, insulation, metal, wood—requires a nuanced strategy. Too much water and you overload already weakened structures. Too little and embers reach new volumes.
Thermal drones, continuous monitoring, rotations, securings: all compose the grammar of a long operation, which can last hours or even days.
The Coming Days: Rehousing, Sanitation, Conditional Resumption
Once the fire is out, the work changes nature. Structures must be checked, zones secured, any risk of re-ignition removed. In attics, an ember can survive a long time.
For evacuees, the urgency is more personal: to recover belongings, papers, a medication left in a room, a coat. Reception units manage these requests one by one, and it is often there that the crisis is measured: in small needs, quiet anxieties.
On the health side, restoring the water network will require testing, purging, confirmations. As long as doubt persists, caution is required.
For the resort, finally, the stake is image as much as reality: show that the evacuation worked, that interagency coordination held, that safety remains a priority despite the unexpected.
What Is Known, And What Remains To Be Determined
Facts are clear for now: a fire started Tuesday, January 27 in the attics of the Grandes Alpes. Then, a spread under the roof and toward neighboring buildings occurred. The intervention 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 propagation, the real extent of the damage.
In Courchevel, snow quickly covers traces. But a fire leaves a memory: the sirens, the empty corridors, and that blaze that, one evening, chose to run under the roofs.
