As the spring season unfolds in Alberta’s mountainous regions, the rise in bear sightings and subsequent trail closures has wildlife officials urging outdoor enthusiasts to exercise caution. With bears emerging from hibernation and searching for food, the potential for human-wildlife encounters is heightened, especially in popular hiking areas.
Spring Awakening: Bears on the Move
According to Nick de Ruyter, the director of WildSmart at the Biosphere of the Bow Valley, this time of year marks a crucial period for bears. “After spending five to six months in their dens, bears are particularly hungry as they emerge in search of food,” he explains. The snowline remains high, but the valley bottoms, where the weather is milder, are abundant with early spring vegetation. “These areas are where their food sources are accessible, and unfortunately, that’s also where we are,” de Ruyter adds.
In Banff National Park, a bear warning was issued recently for Boom, Arnica, and Twin Lakes trails, as well as the Twin Lake campground. This warning follows an incident where a cinnamon-coloured black bear displayed concerning behaviour by closely approaching and shadowing a hiker.
Trail Closures and Warnings
Kananaskis Country is not exempt from this bear activity, with multiple closures and warnings in place this week. The Terrace Trail and Kovach Ski Trails in Spray Lakes Provincial Park are currently off-limits, alongside advisories for Heart Creek Trail, Heart Creek Bunker Trail, and the Trans Canada Trail. These closures come in response to numerous sightings of black bears, including mothers with cubs, near the trails.

With outdoor activities on the rise as warmer weather draws more visitors, the increase in bear encounters is expected. De Ruyter notes that the bears are particularly drawn to early spring flora, such as green grass and dandelions found along roads, trails, and even in residential areas. “It’s typical behaviour for this time of year, so it’s vital that we allow them the space to feed undisturbed,” he asserts.
Safety Tips for Outdoor Enthusiasts
For those venturing into bear country, de Ruyter offers several key safety tips. First and foremost, hikers should be aware of trail warnings and closures prior to their outings. Carrying bear spray is essential, but it is equally important to know how to use it effectively. De Ruyter advises keeping bear spray accessible—ideally in a holster rather than a backpack—so it can be quickly deployed if needed.
Moreover, making noise while hiking can significantly reduce the likelihood of bear encounters. “When you’re on the trail, vocalising can be more effective than bear bells,” he suggests, stating that a loud human voice is more intimidating to wildlife. Hikers should also travel in groups, keep pets on leashes, and maintain a safe distance from any bears they may encounter—ideally at least 100 metres, or about ten school bus lengths.
Seasonal Behaviour Patterns of Bears
As the weeks progress toward summer, bears will gradually ascend to higher elevations. However, as the berry season begins, they will return to the valley bottoms, following the ripening fruit back to their preferred habitats later in the summer months. This seasonal movement underscores the importance of staying informed about bear activity and safety measures, particularly for those who frequent popular hiking trails.

Why it Matters
The rise in bear sightings serves as a reminder of the delicate balance between human recreation and wildlife conservation in Alberta’s natural landscapes. As more people explore these areas, understanding and respecting bear behaviour is crucial not only for personal safety but also for the wellbeing of these magnificent creatures. By fostering a culture of awareness and preparedness, we can ensure that both humans and bears can coexist harmoniously in this stunning wilderness.
