Mount Biddle

A Peak Named for a Traveller

Samuel E.S. Allen, one of the great early explorers of the Canadian Rockies, named Mount Biddle in 1894 after his friend Anthony Joseph Drexel Biddle of Philadelphia—a member of the Appalachian Club described as "an extensive and enthusiastic traveller." Allen first laid eyes on the peak while surveying the Lake O'Hara region and immediately recognized its scale, estimating it at roughly 3,600 metres before modern surveys confirmed 3,320 metres.↗↗↗

The mountain sits at the head of Misko Creek and Opabin Creek, immediately southwest of Lake McArthur, and forms the western buttress of Opabin Pass. Its 731-metre prominence separates it from its taller neighbour Mount Hungabee to the south. The official BC Geographical Names record confirms the name was adopted in 1900 and identifies the peak as being on the east side of Lake McArthur, within Yoho National Park.↗↗↗

The View from Lake McArthur

Mount Biddle's most celebrated role is as the dramatic wall rising above Lake McArthur, a large and incredibly blue lake sitting at approximately 2,100 metres on a high plateau above Lake O'Hara. The lake's unusual sapphire colour—attributed to its depth of 279 feet—is said to be more vivid than neighbouring glacial lakes, and on still days the mountain's face is mirrored in its waters.↗↗

Reaching the lake and its viewpoint requires a hike through the Lake O'Hara trail network, most commonly via the McArthur Pass trail or the Big Larches route. The Lake McArthur circuit from Le Relais Day Shelter is an 8-kilometre loop with 310 metres of elevation gain, passing through larch forests and alpine meadows before the terrain opens up and Mount Biddle comes into full view above the lake.↗

On the Lake O'Hara Alpine Circuit

The Lake O'Hara Alpine Circuit is widely regarded as one of the finest day hikes in the Canadian Rockies. Throughout this challenging loop, Mount Biddle commands the southern skyline. From the lakeshore trail, hikers see the peak and the Schäffer Ridge dominating views to the south and southeast. Climbing toward Wiwaxy Gap, the mountain grows larger. At the Gap itself—at 2,532 metres, the circuit's high point—the view stretches across a panorama where Mount Biddle towers over the entire O'Hara valley below.↗

From All Souls Prospect, another alpine viewpoint along the circuit, hikers look across to see the Schaffler Ridge and Mount Biddle framing the valley from above. The peak's presence is felt at nearly every stage of this 12-kilometre route, making it perhaps the most visually encountered mountain in the Lake O'Hara area.↗

A Rare Summit Objective

Mount Biddle is not a casual hike. The first ascent came on 3 September 1902, when August S. Eggers and Herschel C. Parker were guided up the mountain by the legendary Kaufmann brothers—Christian and Hans—in what was then considered a serious expedition. Allen himself had declared the peak's north face impassable.↗↗

Today, recorded summit attempts are extremely rare. Peakery lists a single modern climb documenting an 18.7-kilometre route with 1,693 metres of gain and a total time exceeding 11 hours, suggesting the approach itself is a substantial undertaking. For most visitors, experiencing Mount Biddle through the lens of the surrounding trails and lakes is the more rewarding (and practical) option.↗

Getting There and Visiting

Mount Biddle sits within Yoho National Park, best accessed through the Lake O'Hara area. Parks Canada operates a reservation-based shuttle from the Lake O'Hara parking area (near the Takakkaw Falls campground along the Yoho Valley Road) to the trailheads at the lake. Access to Lake O'Hara requires advance reservations—day-use permits typically open in April and fill quickly. Alternatively, visitors can hike an 11-kilometre access road to reach the area without a shuttle reservation, though this adds significant distance.↗↗

The Lake O'Hara area has seasonal closures to protect the McArthur Valley–Cataract Brook wildlife corridor used by grizzly bears and mountain goats. The Odaray Plateau is closed from May to November, and the Odaray Highline Trail has a voluntary group limit. Always check current Parks Canada bulletins before planning your routes.↗

The best time to view Mount Biddle with minimal snow is July through September. Early season hikes may encounter lingering snowfields on the alpine routes, and the trails above the treeline are exposed—layers, trekking poles, and bear spray are strongly recommended. The area is well-maintained but remote, with no facilities on the trails themselves.

What Makes This Peak Special

Mount Biddle ranks among the top 10 peaks in both Yoho National Park and the entire Bow Range by elevation. Its combination of height, steep rock walls, and its position overlooking one of the most photogenic alpine lake systems in North America gives it an outsized visual role in the landscape. Despite being the 46th highest peak in British Columbia, it is not a well-known summit name outside mountaineering circles—making the experience of finally seeing the peak you have been gazing at all day across the O'Hara lakes an unexpected thrill for many visitors.↗↗
