The Cool Glacier Route is one of the standard documented climbing lines on Glacier Peak. It is a glaciated alpine ascent with routefinding, crevasse travel, and seasonal snow conditions controlling difficulty. The route typically involves a long approach into remote terrain before reaching the glacier. Objective hazards include crevasses, snow bridges, and rockfall or icefall from surrounding slopes. Conditions can vary substantially with season and year, and late-summer travel may be more broken. It is generally treated as a serious mountaineering route rather than a hiking objective.
