A deadly fire at a crowded bar in the Swiss ski resort of Crans-Montana killed at least 40 people and injured 115 in the early hours of New Year’s Day, as thousands of holidaymakers were celebrating the arrival of 2026.
The blaze broke out at the Constellation lounge bar in the canton of Valais, a popular nightlife spot in one of Switzerland’s best-known Alpine destinations.
Authorities say the fire spread rapidly through the packed, two-story venue, triggering one or more explosions and leaving many victims with severe burns. Swiss prosecutors have opened a criminal investigation to determine how the fire started and why it proved so deadly at the height of the winter tourism season.
A night of celebration turns catastrophic in the Alps
The fire erupted early Thursday morning inside the Constellation lounge bar, located on Crans-Montana’s central street. According to local authorities, the venue was crowded with New Year’s revelers when flames tore through the building, overwhelming those inside within minutes.
The bar has an official capacity of 300 people, with an additional terrace space for 40, according to the resort’s tourism agency. Officials have not confirmed how many people were inside at the time of the fire, but police said many of the victims were young people celebrating the New Year, complicating the identification process.
The public prosecutor’s office in Valais has launched a criminal inquiry into the incident. At an earlier news conference, Beatrice Pilloud, Attorney General for the Valais canton, ruled out the possibility of an attack, saying investigators were focused on identifying the circumstances that led to the blaze, according to The Washington Post.
Local authorities said the fire resulted in a flashover, a phenomenon described by the National Fire Protection Association as “the sudden, simultaneous ignition of everything in a room,” during which temperatures can soar to as much as 1,000 degrees within seconds. Initial findings suggested the flashover led to at least one explosion, according to a statement from the canton.
Swiss officials declined to comment on whether champagne bottles with flames or potential safety violations may have played a role, citing the ongoing investigation. The area surrounding the bar was sealed off, a no-fly zone was imposed, and care centers were set up overnight to support the injured and the families of victims.
A global resort faces questions amid international rescue effort
Crans-Montana is one of Switzerland’s most internationally known ski resorts, famed for its panoramic views of the Matterhorn and Mont Blanc, as well as its luxury hotels, gourmet restaurants, and vibrant nightlife. The resort is owned by U.S.-based Vail Resorts, although Swiss business records show the Constellation bar is not part of that ownership.
In Switzerland, young people can legally buy beer and wine from the age of 16, though spirits are banned for those under 18. Authorities said many of those affected were teenagers and young adults, with families facing agonizing waits for news. “I’ve been looking for my son everywhere for more than 30 hours,” said Laetitia, the mother of a 16-year-old boy who was celebrating with school friends, in comments to France’s BFMTV.
The scale of the injuries has prompted an unprecedented international medical response. Valais officials said about 60 people were treated at Valais Hospital across several sites, while another 60 were transferred to hospitals elsewhere in Switzerland and abroad. Many of the injured suffered severe burns, with Stéphane Ganzer, Head of the Canton’s Security Department, saying that “between 80 and 100” victims were in critical condition.
Patients were moved to specialized burn centers, including Lausanne University Hospital and the University Hospital of Zurich, the only two Swiss facilities equipped to treat burns affecting more than 20 percent of the body. Swiss authorities also coordinated with neighboring countries to secure additional treatment capacity.
Foreign nationals were among those inside the bar, underscoring Crans-Montana’s global appeal during peak ski season. Swiss President Guy Parmelin told Le Temps newspaper that many foreigners were present and said he would not speculate ahead of the investigation’s findings, while vowing consequences for anyone found responsible. At a Thursday news conference, he described the fire as among the worst tragedies in Switzerland’s history.
Several countries confirmed casualties among their citizens. A 19-year-old French footballer, Tahirys Dos Santos of FC Metz, was severely burned and airlifted to Germany for treatment. Australia’s Department of Foreign Affairs and Trade confirmed one Australian was injured, while French and Italian authorities reported multiple citizens injured or missing.
As investigators work to establish the cause of the blaze, the tragedy has cast a shadow over one of the Alps’ most celebrated winter playgrounds. For a resort synonymous with carefree skiing holidays and festive après-ski culture, the events of New Year’s Day have raised difficult questions about safety, crowd management, and emergency preparedness at popular tourist venues.
