At least one hiker has perished and three others have sustained injuries in a tragic rock slide at Banff National Park in Canada.

Rescuers rushed to the park on Thursday afternoon after receiving information that a group had been affected by the deadly rock slide.

The Royal Canadian Mounted Police and Parks Canada later confirmed that one hiker had 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.
