"Just under an hour from Calgary, Coire Dubh Integrale spans six pitches of mixed snow, ice, and rock climbing on Loder Peak. This approachable alpine route offers moderate challenge with reliable rock quality and a rewarding summit view, perfect for climbers seeking a full alpine experience close to town."
Just 45 minutes from Calgary, the Coire Dubh Integrale on Loder Peak offers a compelling alpine adventure that blends ice, snow, and rock climbing into one rewarding day out. This route engages all the senses—the chill of crisp alpine air, the crunch of icy steps beneath your boots, and the firm grip of good-quality rock under your hands. The approach trail carries you through silent, snow-laden forests and across rugged ground, taking roughly 50 minutes before you rack up your gear and start ascending.
The climb itself stretches up to about 6 hours depending on conditions and your pace. Six pitches wind through a dynamic landscape: glassy ice sections that demand precise ice screw placements, snow slopes that shift with the sun and weather, and rock pitches where solid cams and nuts secure your progress. The rock quality rarely disappoints, generally stable enough to inspire confidence yet sometimes testing your route-finding when winter’s grip loosens the grip of the snow. If the snowpack is deep, the rock pitches stay mellow; when it's scarce, those same sections spike in difficulty.
Despite the moderate grade of 5.7 with WI3 ice, the route has enough variety and exposure to keep you fully engaged without overwhelming commitment. The summit of Loder Peak rewards your efforts with sweeping views of the Bow Valley, where the landscape spreads wide and raw, and the distant peaks freshen the horizon.
Descending demands similar respect. It takes between 1.5 to 2.5 hours to safely navigate your way down, often involving a mix of downclimbing and rappel. The descent can be as tricky as the ascent, particularly if winter conditions grip tight.
Sunlight barely filters through in winter, so start early and dress in layers to manage the cold. Gear up for ice screws—count on carrying 6 or more—as well as cams up to 2 inches and a selection of small to medium nuts. Tri-cams come recommended for snagging tricky pockets, and carrying some pins might save you in unexpected spots.
Coire Dubh Integrale is as close to a full alpine day as you can get without sinking deep into the backcountry. It’s an excellent choice for anyone seeking a solid mix of climbing styles with minimal approach time but maximum alpine character, ideal for winter and early spring conditions in the Canadian Rockies. Prepare well, expect changing terrain, and get ready to meet the mountain on its terms.
Be cautious on the descent; some sections have limited ledge space and can be icy, making downclimbing or rappelling technical. Keep an eye on changing snow conditions that can loosen protection placements or expose more difficult rock.
Start before dawn to maximize daylight and avoid icy shade on the route.
Wear layered clothing to adjust as you transition between snowy slopes and exposed rock.
Check recent weather and snow reports closely; conditions can shift the rock pitches from moderate to challenging.
Prepare for a mixed descent of rappelling and downclimbing—bring the necessary webbing and anchor material.
Bring 6+ ice screws for the ice pitches, a full rack of cams up to 2-inch, plus small to medium nuts. Tri-cams are handy for tricky pockets, and a few pins could come in useful depending on snow coverage and rock condition.
