 From here an airy and challenging scramble up the peak's north ridge is required to attain the summit.The ascent is a challenging climb by the standards of British mountains, being an exposed scramble at Grade 2 standard.The south face of the mountain, by contrast, falls sheer to the bealach between Sgùrr MhicChoinnich and Sgùrr Thearlaich, and the easiest route up this face (King's Chimney) is a V. Diff rock climb.
