North Ridge

The Linda Glacier Route is one of the standard alpine routes on Aoraki / Mount Cook and is widely documented in New Zealand climbing references. It is a serious glaciated ascent involving snow and ice travel, crevasse hazards, and objective avalanche and serac danger depending on conditions. The route is commonly used as a normal route from the east side of the mountain. Conditions on the glacier and upper slopes can change rapidly, and route-finding is important. It is a full mountaineering objective rather than a trekking route.

The East Ridge is a major alpine route on Aoraki / Mount Cook and is known as a more technical and committing line than the glacier routes. It typically involves mixed climbing on exposed ridge terrain with rock, snow, and ice sections. The route is serious in both objective hazard and route-finding, and conditions can vary substantially with snow cover and ice. It is a classic mountaineering line rather than a hiking route. Parties generally need strong alpine skills and favorable weather.

Zurbriggen Ridge is a documented alpine route on Aoraki / Mount Cook and is regarded as a serious technical climb. It follows a prominent ridge line and usually involves exposed mixed climbing with snow and ice. The route is more committing than the standard glacier ascent and demands solid alpine judgment. Rockfall, icefall, and changing snow conditions are important hazards. It is a genuine mountaineering objective on New Zealand's highest peak.
