Aoraki / Mount Cook

Aoraki’s summit has dropped three metres in recent decades. The 1991 rockfall that removed the top of the peak reduced it from 3,764 metres to 3,724 metres, and the Tasman Glacier has retreated so significantly that the lake at its terminal face, which barely existed in the 1970s, is now kilometres long. Visiting the Mount Cook area without knowing these things is possible; visiting it with them gives the landscape a more honest character than the standard “spectacular scenery” framing provides.

The Walks

The Hooker Valley Track is the essential walk and one of the better day hikes in New Zealand: 10 kilometres return, three swing bridges over glacial streams, and a view from the terminal lake at the end that includes icebergs calved from the Hooker Glacier with the mountain behind. Allow three to four hours. Start early to have the light on the mountain from the front rather than behind.

The Tasman Glacier Lake Walk is shorter (two hours return) and reaches the terminal lake of the Tasman Glacier, New Zealand’s largest. The glacier is retreating at roughly 180 metres per year; what you see from the viewpoint above the lake is the evidence of that process rather than the glacier at its historical scale.

Mueller Hut, above the village on the ridge, requires a full day and serious fitness. The views are genuinely alpine and the hut has beds available through DOC booking. This is not a casual undertaking.

The Dark Sky

The Aoraki Mackenzie International Dark Sky Reserve surrounding the area is the world’s largest dark sky reserve. On a clear moonless night from the Hooker Valley or the Lake Pukaki foreshore, the Milky Way is visible as a textured band across the sky and the Magellanic Clouds (two dwarf galaxies visible only from the Southern Hemisphere) are naked-eye objects. This is not a minor bonus to the mountain; for some visitors it is the primary reason to come.

Getting There

Mount Cook Village is 3.5 hours from Christchurch via Lake Pukaki (State Highway 1 then 80). The approach through the Mackenzie Basin with the lake and mountain visible ahead is one of the better driving approaches in the South Island. There is no train; the village is accessible only by road. Fly-drive from Christchurch is the practical option.

Staying and Eating

The Hermitage Hotel is the only significant hotel in the village, with several price tiers. The Alpine Grill does good food with mountain views. The DOC campground at White Horse Hill is a fifteen-minute walk from the Hooker Valley trailhead and significantly cheaper than the Hermitage.
