A catastrophic rockfall struck a popular hiking trail near Bow Glacier Falls in Banff National Park on Thursday, resulting in at least one fatality and several injuries. Emergency teams continue searching the area as fears remain that more individuals could still be missing.
The incident occurred early Thursday afternoon, catching hikers off guard during what had been a routine day on the scenic trail. The path, which begins at Bow Lake, is well-known for its stunning alpine views and moderate difficulty, drawing outdoor enthusiasts year-round.
Sudden Collapse Sparks Emergency Response
Around 1:30 p.m., witnesses reported hearing a loud cracking noise, followed by a massive slide of rock and debris crashing down in the vicinity of the falls. One hiker, who declined to be named, described seeing the falling rocks and realizing people were in the direct path.
“It was terrifying—everything happened so quickly. I immediately activated my SOS beacon and reached out to emergency services,” the witness said.
Emergency units from multiple jurisdictions, including Parks Canada, RCMP, Alberta EMS, and the STARS air ambulance team, were dispatched within minutes. Two helicopters airlifted injured victims to Calgary’s Foothills Medical Centre. Another person was transported by ground ambulance. Their medical conditions have not been officially released.
One Death Confirmed, More May Be Missing
Authorities later confirmed that one individual was pronounced dead at the scene. A social media post from a local hiking group, Slow & Steady Hikers, identified the victim as a member of their team. Another hiker from the group sustained a broken arm, while others managed to escape unharmed.
“It’s devastating to lose a member of our hiking community,” the group posted. “Our hearts are with their family.”
Search teams are using drones, canine units, and ground personnel to comb through the debris field to ensure no one else remains trapped. Efforts were paused at nightfall and resumed at dawn Friday morning.
“If you suspect someone you know may have been hiking in the area on Thursday and has not returned, please call Parks Canada Dispatch at 403-762-1470,” officials said in a joint statement.
Bow Lake Trail Closed; Airspace Restricted
In the aftermath of the disaster, authorities have closed Bow Lake and the Bow Glacier Falls trail to all visitors. A no-fly zone has also been implemented to protect aerial search operations and maintain the safety of those on the ground.
Officials have assured that guests at the Alpine Club of Canada’s Bow Hut are safe and will be permitted to return via the standard route, which remains secure.
Geological experts are expected to assess the slope in the coming days to determine the cause and stability of the surrounding terrain.

Witness Recounts Harrowing Scene
Another hiker present during the slide said the water near the falls appeared to be flowing more rapidly than usual moments before the incident. As they turned to take photos, a loud sound shattered the calm. What followed was a scene of chaos as hikers tried to flee from the falling debris.
Medical tents were quickly set up at the Bow Lake day-use area where paramedics triaged injuries. Ambulances lined the parking area as helicopters circled above. Witnesses reported seeing several people taken from the scene for treatment.
“I saw people helping each other. It was terrifying, but everyone did their best to stay calm and support those injured,” said one hiker.
Officials and Leaders Respond
The event drew swift responses from federal and provincial officials. Parks Canada CEO Ron Hallman expressed sorrow over the loss of life and extended gratitude to the teams working in difficult conditions.
“On behalf of Parks Canada, our condolences go out to those affected by this tragedy,” Hallman said. “Our staff and supporting agencies have shown professionalism and courage under extreme pressure.”
Alberta Premier Danielle Smith also issued a public statement on social media, offering thoughts and prayers for those affected and praising the work of emergency crews.
Health Minister Matt Jones said the provincial government was coordinating closely with rescue and medical teams. “Our thoughts are with the victims and their families. We are grateful for the swift action by first responders and healthcare workers.”
Ongoing Safety Measures
The trail to Bow Glacier Falls is one of the park’s most visited routes, known for its glacial landscapes and clear mountain waters. Despite being considered a moderate hike, mountain conditions can be unpredictable. Parks Canada officials noted that natural erosion and weather changes can increase risks, especially during spring and early summer.
The Icefields Parkway remains open, though traffic disruptions are expected near Bow Lake to allow crews uninterrupted access to the site. Drivers are advised to prepare for brief delays.
Investigation Underway
An investigation into the cause of the rockfall is ongoing. Geotechnical experts will conduct a detailed review of the site to identify contributing factors. In the meantime, officials continue to prioritize search and rescue efforts over recovery and assessment.
More updates will be shared as the situation evolves.
