Mount Sir Donald’s Northwest Ridge stands as a towering invitation for climbers eager to experience one of the most compelling moderate alpine rock routes found across the Selkirk Mountains. The route stretches nearly 2400 feet, offering a sustained adventure that blends steady exposure with technical moves rarely exceeding 5.4, tinged with an ‘X’ for the bold commitment it demands. Approaching the climb, the trail carves its way through a rugged, bear-country forest, a reminder that wilderness is alive around you with rustling branches and distant wildlife calls that intrigue as much as caution.

Once you’ve gained the Sir Donald-Uto col, the ridge draws you forward with a promise of direct, uninterrupted line to the summit. The climbing sticks closely to the ridge itself—straying even a few feet often leads you back, as the ridge’s natural path protects you from loose rock or more complex terrain. Most climbing falls into the 4th class range, with regular but manageable 5th class sections that test your balance, route-finding, and steady footwork. Sticky approach shoes or well-worn boots will serve you well on the often smooth rock sections, especially given the potential for scattered snow patches through early season or leftover winter cornices.

The route is rewarding both visually and physically: from the sharper angles of the lower ridge to the softer gradient in the final few hundred feet, the mountain reveals more options—the western face offers subtle sidesteps for those feeling adventurous, but sticking to the ridge remains the most straightforward path. As clouds or moisture threaten, remember the rock’s slick nature—wet conditions make the granite treacherous, demanding heightened attentiveness and possibly rethinking timing. Planning for a dry forecast is smart.

Descent demands respect and forethought. Retracing the route remains the favored strategy, with mostly straightforward downclimbing punctuated by a handful of short rappels that require caution as gravity pushes you closer to the face. About two-thirds down, bolted rappel anchors mark a safer alternative to downclimbing, guiding you through a sequence of roughly 12 rappels around 25 meters each. This approach eases the descent in daylight but significantly complicates things if attempted by headlamp. An alternative descent via the northeast ridge and a broad ledge system to the west face exists but carries uncertainty and might necessitate an ice axe, especially if snow or ice linger.

Protection on the Northwest Ridge calls for versatility. A rope is essential unless soloing with extreme skill and confidence, yet carrying a slim rope for rappels is a smart backup in case the weather changes. A small rack with nuts and cams up to hand size covers most placements, though the long nature of the route makes pitching infrequent unless planning to bivy. This climb is a test of endurance, steady judgment, and readiness for alpine conditions rather than technical cruxes.

This route may not be crowded—its raw, classic appeal hasn’t attracted crowds despite its inclusion in the Fifty Classics. Weather permitting, it is possible to hike to the start in under three hours, making a sunrise start ideal. Climbing the Northwest Ridge car-to-car is satisfying, but patience and respect for the mountain’s pace remain key ingredients for success. With vivid exposure, the steady pulse of quiet wilderness, and a rewarding summit panorama, it’s a route that imparts both challenge and calm in equal measure.
