The rise in bear encounters and subsequent trail closures across Alberta’s mountain parks has prompted wildlife specialists to urge visitors to exercise caution while exploring bear territory. With bears emerging from hibernation and actively searching for food, the risk of human-wildlife interactions has heightened significantly.
Spring Awakening of Bears
As spring unfolds, bears are emerging from their dens after months of dormancy. Nick de Ruyter, the WildSmart director at the Biosphere of the Bow Valley, explains, “At springtime, all the bears just got out of their dens after five to six months of laying in their dens, and they’re hungry. They’re looking for food.” With snow lingering in higher elevations and ample food available in the valley bottoms, bears are gravitating towards areas frequented by humans.
Recent events in Banff National Park illustrate the growing concern: a bear warning was issued for the Boom, Arnica, and Twin Lakes trails, along with the Twin Lake campground, due to a cinnamon-coloured black bear displaying alarming behaviour by closely following a hiker.
Trail Closures and Safety Precautions
Kananaskis Country has also seen an uptick in bear warnings and closures. Key areas, including the Terrace Trail and Kovach Ski Trails in Spray Lakes Provincial Park, have been affected, with warnings issued for the Heart Creek Trail and surrounding routes. Numerous sightings of black bears, including mothers with cubs, have contributed to these advisories.

As outdoor activities increase with warmer weather, de Ruyter notes that the presence of bears is becoming more pronounced. “Right now, the easiest food they’re keying on is that green grass and dandelions, which is often found along roads, highways, trails, campgrounds, parks, and backyards — places where we are as people,” he stated. It’s crucial that bears are allowed to feed undisturbed during this critical time.
Essential Tips for Backcountry Users
For those planning excursions into the backcountry, de Ruyter offers essential advice. Checking for trail warnings and closures is imperative. He strongly recommends purchasing bear spray, ensuring one knows how to use it effectively, and carrying it on one’s person rather than stowing it in a backpack.
Visitors should also be mindful of making their presence known in the wilderness. “Making noise is key, and going in a group is ideal. I use my voice — ‘Hey-oh!’ — which is much more effective than bear bells, as they’re just not loud enough,” he advises. By travelling in groups, hikers can make more noise, which can deter wildlife. It’s equally important to keep pets leashed and to maintain a safe distance from any bears encountered. “If you don’t get close to a bear, you’re not going to have a problem with a bear,” de Ruyter added.
The Seasonal Movement of Bears
Over the coming months, bears will gradually ascend to higher elevations. As berry season approaches, they will return to the valley bottoms before moving back up to higher ground as berries ripen later in the summer. For the latest updates on trail warnings and closures, visitors can refer to the Biosphere Institute of the Bow Valley’s online resources.

Why it Matters
The increase in bear sightings and human encounters in Alberta’s mountain parks underscores the delicate balance between wildlife conservation and human recreation. As bears emerge from hibernation, understanding their behaviour and ensuring safety for both wildlife and park visitors is essential. By fostering awareness and practising responsible outdoor habits, we can help protect these majestic creatures while enjoying the natural beauty of Alberta’s landscapes.
