After you leave the Yamnuska parking lot near the information kiosk, you follow a wide trail as it crosses a gravel road and then climbs for 800 m to a Y-junction. Beyond this junction, the trail to the left is a climber's access trail leading to the face of Mount Yamnuska; there is a high likelihood of dangerous rockfall in this area and it is not recommended for hikers. The trail to the right leads to the East Ridge of Yamnuska. This portion of the trail ends with a small loop with beautiful views on the summit of the ridge. If you are not a comfortable and competent scrambler, you should enjoy the views and then turn around and return via the same trail.
Continuing beyond the East Ridge Trail, a cliff blocks the route at the “Chimney” and Yamnuska becomes a scramble in alpine terrain with significant exposure and loose rock. This section requires good route-finding skills. Many people have become lost on this side of the mountain, suffered from exposure to the elements and some unfortunate people have died. If you are in any way unsure of your abilities, please turn around and do not risk putting your friends and family through this tragedy.
Following the scramble section of Mount Yamnuska, the West Col Descent traverses the front of the mountain, returning to the first junction and you return to the Yamnuska parking lot, on the original 800 m of trail you followed while leaving the parking lot.
Please note: With over 150 climbing routes up the face, it is critical that hikers do not throw rocks over the edge.
