This route is a step up in commitment, difficulty and reward from the standard South side. Early season is best. A second ice tool can be useful, as can ice screws. While a one day ascent is common, camping at Illumination Saddle the night before will reward you with great views and an early and well rested start. Bring the backcountry skis for a great ski down after breaking camp.
