This limited access area of Yoho National Park is named for Lake O'Hara. But Lake McArthur, situated in a hanging valley surrounded on three sides by Schaffer Ridge, Mount Biddle and Park Mountain, is roughly twice the size of Lake O'Hara, and definitely worth a visit.
Cooler autumn temperatures and a bit of precipitation finally put out most of the forest fires in BC and Alberta. As the skies cleared and the summer crowds thinned out, we closed out the 2017 conventional hiking season with an up and back hike to the high point along the Iceline Trail in Yoho National Park. The majority of the trail is across barren landscape that was covered by glaciers just a hundred years ago. Pioneering alpine shrubs added touches of warm, fall colour to the rocky terrain - a beautiful contrast to the icy pools of turquoise glacier melt.
One of our favourite destinations during wildflower season, Grizzly Peak is also a solid option for larch season. Less well-known than the crowded trails around Lake Louise, it's a half-day hike that's easy to extend with a ridge walk or an exploration of Pocaterra Cirque.
Despite more than 20 years of hiking experience, we occasionally blow our trip planning. So while we thoroughly enjoyed the varied landscape and fantastic scenery just beyond Bow Hut, we didn't even know to hike up The Onion for an overhead view of Iceberg Lake. That's a good reason to hike this trail again - soon!
While not the most scenic hike, there is definitely a fun factor to this half-day outing - creek crossings, rock-hopping, pictographs, waterfalls and rock climbers are all appealing. Natural turnaround points are at the waterfall (approx. 2 km return) and at the hoodoos (approx. 6 km return). The steep canyon walls and creek can be a cool respite on hot summer days. In the winter, ice cleats should be considered essential for this trail.
