AT least one hiker has died and three others injured in a horror rock slide at Banff National Park in Canada.

Rescuers scrambled to the park on Thursday afternoon after receiving reports that a group had been struck by the deadly rock slide.

The Royal Canadian Mounted Police and Parks Canada later confirmed one hiker tragically died and three were injured near Bow Glacier Falls.

The beauty spot is north of Lake Louise on the Icefields Parkway, about 124 miles northwest of Calgary.

It is also roughly 85 miles from the site of the G7 summit held in Kananaskis, Alberta, this week.

STARS Air Ambulance spokeswoman Kate Langille earlier said two of its units were deployed around 2pm local time.

Parks Canada has urged tourists to avoid the area.

The Bow Glacier Falls hiking trail is 6-mile route running along the edges of Bow Lake.

It’s considered a moderate challenge for hikers and day-trippers include families.

Alberta Premier Danielle Smith said she was deeply saddened.

“We are thinking of all those involved and wishing for their safety as we await further details,” she said in a post on social media.

In August 2023, a rockfall occurred in the same area when a section of a wall broke off and smashed down the mountainside.

Despite a lot of the debris getting stopped by a ledge, several people were injured.

One tourist even broke her arm or shoulder as she desperately ran to safety.

In May, a Swiss town was buried by an avalanche sparked by a falling glacier, forcing residents to desperately evacuate.

A massive cloud of ice and debris came crashing down the mountain after a huge chunk of the Birch glacier broke off, wiping out the village of Blatten.

Fortunately, the 300 residents were evacuated a week earlier after experts warned them of the impending danger.
