As spring unfolds in Alberta’s mountainous regions, wildlife experts are raising alarms over an uptick in bear sightings and subsequent trail closures. With bears emerging from hibernation, the potential for encounters with outdoor enthusiasts is heightened, prompting calls for increased vigilance among hikers and campers alike.
Increased Bear Activity This Spring
Nick de Ruyter, the director of WildSmart at the Biosphere of the Bow Valley, emphasises that the spring season is particularly critical for bear activity. “After spending five to six months in their dens, bears are emerging hungry and searching for food,” he explained. “As the weather improves in the valley bottoms, bears are drawn to areas where food sources, such as green grass and dandelions, are readily available. This overlap with human activity can lead to dangerous encounters.”
In Banff National Park, a bear warning was issued this week for trails including Boom, Arnica, and Twin Lakes, alongside Twin Lake campground. The alert followed reports of a cinnamon-coloured black bear exhibiting alarming behaviour by closely following a hiker.
Closures and Warnings in Kananaskis Country
The situation is similarly concerning in Kananaskis Country, where several trails have been closed or marked with warnings. Recent sightings of black bears, including some with cubs, have prompted advisories for areas such as the Terrace Trail, Kovach Ski Trails, and Heart Creek Trail. On Monday, warnings were issued specifically for the Heart Creek Trail and the Trans Canada Trail, indicating a growing need for caution among those venturing into the backcountry.

With an increasing number of people heading into the mountains as the weather warms, de Ruyter notes that the likelihood of bear encounters is on the rise. “It’s typical for this time of year,” he stated. “We must ensure that bears are not disturbed while they search for food.”
Essential Safety Tips for Outdoor Enthusiasts
For those planning to explore Alberta’s backcountry, de Ruyter offers crucial advice. “Check for trail warnings and closures before you set out. It’s advisable to carry bear spray, ensure you know how to use it, and keep it accessible—never stow it in your backpack,” he advised.
De Ruyter also encourages hikers to make their presence known while on the trails. “Making noise is key, and hiking in groups is ideal. Using your voice—like a simple ‘Hey-oh!’—is more effective than bear bells, which often aren’t loud enough. Keeping pets on leashes and maintaining a safe distance from wildlife are essential to minimise risks.”
He further advises that a distance of at least 100 metres, or approximately ten school bus lengths, should be maintained from any bear encountered.
Understanding Bear Behaviour This Season
As summer approaches, bears will gradually ascend to higher elevations. However, with the arrival of berry season, they will return to the valley bottoms before eventually migrating back up as the berries ripen. This seasonal movement underscores the importance of staying informed about bear activity and adhering to safety recommendations.

All current warnings and closures in Banff National Park and Kananaskis Country can be found on the Biosphere Institute of the Bow Valley’s website, ensuring outdoor enthusiasts remain updated on the latest developments.
Why it Matters
The increase in bear sightings in Alberta serves as a crucial reminder of the delicate balance between wildlife and human activity. As more people venture into these natural spaces, understanding and respecting wildlife behaviour becomes imperative. Ensuring the safety of both bears and humans not only protects individuals but also preserves the integrity of Alberta’s stunning ecosystems. Awareness and preparedness can significantly reduce the risk of dangerous encounters, fostering a harmonious coexistence in the great outdoors.
