Trail upgrades in 2021 improved scramble conditions to the summit of Yamnuska. But this is still a challenging half-day adventure, especially daunting for those with any fear of heights/exposure.
This one is a long day, especially if you spend any time exploring the geology of The Onion or searching for "ice caves" along the edge of the Wapta icefield. It fits the definition of a Class 1 scramble. The toughest bits are getting up and over the chokestone and then going up the rock ledges above Bow Hut, to The Onion. The views from the summit are well worth the effort.
The fairly extensive network of trails in the lesser-known south part of Bow Valley Provincial Park is a solid option for maintaining conditioning over the winter months, family picnics, fall colours, bird spotting and more.
Although Bow Valley Campground closes to campers each winter, area trails are still accessible for winter hiking, birdwatching and photography. Visitors can tailor the hiking distance to suit the weather conditions and the capabilities of the group, with routes ranging from 2 to 10+ km,
Now part of Bow Valley Wildland Provincial Park, the former Yamnuska Natural Area features a network of unsigned trails that weave around multiple ponds and small lakes. With lots of options for out-and back and loop hikes of various distances, it's a good destination to explore with kids. Just be sure to stay away from the south end, which neighbours the area's landfill!
