As warmer weather lures outdoor enthusiasts into Alberta’s breathtaking mountain parks, wildlife experts are issuing urgent reminders about the rising number of bear encounters. With bears emerging from hibernation and actively searching for food, it is imperative for hikers and campers to exercise caution and respect the natural habitat of these majestic creatures.
Bear Activity on the Rise
Nick de Ruyter, director of WildSmart at the Biosphere of the Bow Valley, explains that spring heralds a time of heightened bear activity. “After spending five to six months hibernating, bears are emerging from their dens, and they are hungry,” he stated. With snow still blanketing higher elevations, bears are gravitating towards the valley bottoms where food sources like fresh grass and dandelions are more readily available.
Recent warnings issued by Parks Canada highlight the seriousness of the situation. In Banff National Park, a bear warning was declared for Boom, Arnica, and Twin Lakes trails, as well as the nearby Twin Lake campground. This advisory follows an incident involving a cinnamon-coloured black bear that displayed concerning behaviour by closely following a hiker.
Trail Closures and Warnings
Kananaskis Country is not exempt from these bear sightings, with several closures and warnings being released this week. Areas impacted include the Terrace Trail and Kovach Ski Trails in Spray Lakes Provincial Park, as well as the Heart Creek Trail, Heart Creek Bunker Trail, and Trans Canada Trail. There have been multiple reports of black bears, some with cubs, close to these popular trails.

As the number of visitors to the mountains increases, de Ruyter notes that the chance of bear encounters rises correspondingly. “The easiest food for bears to find right now is typically along roads and trails, where hikers often tread,” he remarked. “It’s crucial that bears are left undisturbed while they forage.”
Essential Safety Tips for Hikers
For those planning to explore Alberta’s backcountry, de Ruyter has shared several important safety measures. Firstly, hikers should always check for trail warnings and closures before heading out. Bear spray is a must-have for anyone venturing into bear country; it should be carried on one’s person rather than in a backpack, and users must be familiar with its operation.
Noise is a critical factor in preventing bear encounters. De Ruyter advises that making sounds while hiking—such as calling out—can help alert bears to human presence. “The human voice is far more effective than bear bells,” he noted. Additionally, hiking in groups is encouraged as it allows for more noise and can deter wildlife. Keeping pets on a leash is also paramount, as loose animals can provoke unwanted bear interactions.
Understanding Bear Behaviour
As spring progresses into summer, bear behaviour will shift. De Ruyter explains that bears will gradually ascend to higher elevations, only to return to the valley bottoms when berry season begins. They will continue this pattern of movement as food sources ripen throughout the summer months.

For those concerned about their safety in bear territory, it is advisable to maintain a distance of at least 100 metres—approximately the length of ten school buses—should they encounter a bear. “If you don’t approach a bear, you are unlikely to encounter any issues,” de Ruyter reassured.
Current updates on bear warnings and trail closures in Banff National Park and Kananaskis Country can be found on the Biosphere Institute of the Bow Valley’s website.
Why it Matters
As Alberta’s natural landscapes draw more visitors, the balance between outdoor recreation and wildlife conservation becomes increasingly delicate. Understanding bear behaviour and taking appropriate safety precautions are essential not just for individual safety, but for the preservation of the natural ecosystem. Ensuring that bears can forage peacefully helps maintain the health of these magnificent creatures and their habitats, fostering a harmonious coexistence between humans and wildlife in one of Canada’s most stunning regions.
