Multiple Grizzly Bears Prompt Trail Closure and Widespread Bear Warning in Kananaskis

Visitors heading to one of Kananaskis Country's busiest recreation areas this weekend are being urged to stay alert after Alberta Parks issued a widespread bear warning and closed part of the popular Upper Kananaskis Lake Circuit because of increased grizzly bear activity.

The warning covers nearly the entire Kananaskis Lakes area, including campgrounds, day-use areas and trails along the Kananaskis Lakes Trail Road from Highway 40 to Upper Kananaskis Lake (map here), as well as the Spray Road corridor between the Kananaskis Lakes Trail and Lower Kananaskis Lake.

The advisory comes as multiple grizzly bears, including several females with cubs of varying ages, have been repeatedly observed using the area.

Officials say one grizzly sow raising her first litter has shown defensive behaviour after being surprised by people at close range. In those encounters, the bear responded with bluff charges, a warning behaviour intended to create space rather than initiate an attack.

In response, Alberta Parks closed the western portion of the Upper Kananaskis Lake Circuit on July 15. The closure extends from the North Interlakes Trailhead to the White Spruce Day Use Area and includes the 1982 Canadian Mount Everest Expedition Interpretive Trail and all shoreline access within the closed section.

The White Spruce Day Use Area remains open for parking, while access to Point and Aster Lake backcountry campgrounds is unaffected.

The broader bear warning remains in effect until further notice.

Unlike a closure, a bear warning does not prohibit access. Instead, it signals that visitors entering the area should expect an elevated likelihood of encountering wildlife and take additional precautions.

Park officials recommend travelling in tight groups of four or more, making frequent noise, keeping dogs on short leashes and carrying bear spray where it can be accessed immediately rather than stored inside a backpack.

Visitors are also being advised to avoid running or cycling through the area, as higher speeds reduce reaction time and increase the chances of surprising a bear around corners or in dense vegetation.

If a bear is encountered at close range, officials advise remaining calm, speaking in a low voice, grouping together, preparing bear spray and slowly backing away while giving the animal an escape route. Running, shouting or separating a mother from her cubs can increase the risk of escalation.

The warning arrives during the height of berry season, when bears become increasingly active in valley bottoms and around lakeshores as they build fat reserves ahead of winter. Female grizzlies with cubs are often especially cautious, reacting defensively when they perceive people as threats.

Alberta Parks is asking anyone who sees a bear in the area to report the sighting immediately by calling 403-591-7755. The warning and trail closure will remain in place until wildlife officials determine the area is safe to reopen.
