How tall is Aoraki/Mount Cook?

Aoraki/Mount Cook stands 3,724 metres above sea level. This is its current surveyed height. The summit was previously listed at 3,755 metres, but a large rock and ice collapse in 1991 removed material from the summit cone and reduced the height. It remains New Zealand's highest mountain.

How long is the Tasman Glacier?

The Tasman Glacier is around 27 kilometres long, making it the longest glacier in New Zealand. It has been retreating for decades, and its snout now terminates in Tasman Lake — a glacial lake that formed as the glacier retreated and has grown significantly since the 1970s. Boat tours on the lake take visitors among the icebergs calved from the glacier face.

What walks can you do at Mount Cook?

The most popular walks from Mount Cook Village include the Hooker Valley Track (10km return, 3 hours, crosses swing bridges above glacial streams with views of Aoraki), the Tasman Glacier View Track (short, leads to a viewpoint above the glacier), and the Red Tarns Track (moderate, 1.5 hours return, for elevated views of the village). The Hooker Valley Track is one of the most accessible high-country walks in New Zealand.

Can non-climbers visit Aoraki/Mount Cook?

Yes — the area around Mount Cook Village is accessible to anyone with a vehicle and reasonable fitness. Walking tracks, boat tours on Tasman Lake, and ski-plane or helicopter flights over the glacier are available to non-climbers. Aoraki itself requires technical mountaineering skills and experience; it is not a hiking objective. The mountain was first climbed in 1894 and remains one of the more serious mountaineering objectives in the Southern Hemisphere.

Aoraki/Mount Cook and the Tasman Glacier: New Zealand's Highest Peak

At 3,724 metres, Aoraki/Mount Cook is the highest mountain in New Zealand. It stands in the centre of the Southern Alps, in a national park that bears its name, at the head of a broad glacial valley that funnels cold air down from the snowfields above. Below its southeast face, the Tasman Glacier flows for around 27 kilometres toward a lake that formed only in the last few decades as the ice retreated. The entire landscape is geologically young, actively changing, and vast in a way that photographs do not adequately convey.

Aoraki — The Cloud Piercer

New Zealand's highest mountain

3,724 m Aoraki/Mount Cook National Park

Aoraki means "cloud piercer" in Māori — an accurate description of a peak that frequently disappears above cloud cover and creates its own weather. In Ngāi Tahu tradition, Aoraki and his brothers became the South Island's mountains when their canoe ran aground and tilted; the passengers, turned to stone, became the Southern Alps. The mountain was given its dual name — Aoraki/Mount Cook — in 1998 as part of a Treaty of Waitangi settlement with Ngāi Tahu.

The mountain's current height is 3,724 metres — lower than its previous listed height of 3,755 metres after a major rockfall and ice collapse in 1991 removed material from the summit cone. It is still the highest point in New Zealand and one of the most serious mountaineering objectives in the Southern Hemisphere. Edmund Hillary trained on these flanks before his Everest ascent in 1953.

The Tasman Glacier

New Zealand's longest glacier — and a new lake

~27 km long Tasman Lake

The Tasman Glacier flows approximately 27 kilometres from the neve (snow accumulation zone) above to the terminal lake below. It is the longest glacier in New Zealand. Like most of the world's glaciers, it has been retreating for decades: the terminal face has retreated several kilometres since systematic measurement began, and the process has accelerated in recent decades.

Tasman Lake — the lake at the glacier's snout — did not exist 50 years ago. It has formed as the glacier has retreated, fed by meltwater and bounded by lateral moraines. The lake is now several kilometres long and filled with icebergs calved from the glacier face. Boat tours operate on the lake, threading through the ice in small inflatable vessels close to the calving face. It is a landscape mid-transformation.

Hooker Valley Track

10 km return 3 hours

The most accessible walk in the national park is the Hooker Valley Track from Mount Cook Village. The 10km return trail crosses three swing bridges above glacial streams and ends at Hooker Lake, with a direct view across the water to Aoraki's south face. The walk is straightforward, well-formed, and achievable for most reasonably fit visitors — no technical skills required. Hooker Lake also contains icebergs in cooler months.

Weather: Aoraki/Mount Cook National Park generates its own severe weather with little warning. Afternoon thunderstorms, sudden cloud, and high winds are common even in summer. Check the forecast before any walk and carry warm, waterproof gear regardless of the morning conditions. The Department of Conservation visitor centre in Mount Cook Village has current conditions and advice.
