Select participants and date
The rope hums as it slides through a belay device and the Athabasca river keeps time a few dozen meters away—its current a cold, relentless metronome. You step onto the foot of a broad limestone slab, toes searching for a seam, and feel the rock push back in the clean, tactile language climbers understand. The sky over Jasper is a hard, clear dome and beyond the river the Rockies rise in layers of grey and ochre.

Adventure Tips
Arrive hydrated
Bring at least 1–1.5 L of water per person—cold river air can mask dehydration and the activity is deceptively aerobic.
Wear grippy approach shoes
Climbing shoes are provided, but sturdy approach shoes are best for the 10-minute hike to the crag and for standing on loose scree.
Layer for variable weather
Mountain weather shifts quickly—pack a lightweight windproof and a warm mid-layer even on warm days.
Listen to the guide
Belay commands and anchor briefings are taught on-site—follow instructions closely for safety and efficiency.
