New Zealand's highest mountain at 3,724 metres, an ancestor turned to stone for Ngāi Tahu, approached on swing bridges under some of Earth's darkest skies.

Spring opens: Glacier Explorers relaunches on 1 September as the Tasman lake thaws, snow starts to leave the valley tracks, and the Milky Way's core still crowds the early-night sky.

Year-round The turquoise lakes, glaciers and alpenglow-lit summit are here year-round; summer eases the valley walks, and clear dark nights bring the Milky Way.

Aoraki is the highest mountain in New Zealand, 3,724 metres of rock and ice at the head of a valley in the Southern Alps, and nobody stands on its very top. For Ngāi Tahu, the people of the South Island, it is an ancestor turned to stone. In their telling the island is Te Waka o Aoraki, the canoe Aoraki and his brothers came down from the sky in. It struck a reef, and the crew who climbed onto the upturned hull froze there into the range. Standing on the summit would be treading on his head, so guided parties stop a few metres short. The top is not even fixed. Just after midnight on 14 December 1991 the summit ridge collapsed onto the glacier below, and the mountain lost about ten metres in a night. The road in runs the length of Lake Pukaki, milky turquoise from rock the glaciers have ground to powder, with Aoraki growing larger ahead of you the whole way. On a still morning the mountain lies out flat on the water. The Hooker Valley track is flat almost the entire way, so what tires you is the wind and the distance, not any climbing. It crosses a braided river three times on bridges that swing under your feet, over moraine the glacier stood on a century ago. There is no shelter on it, and the weather turns inside an hour. It ends at an iceberg-dotted lake under the south face. Further in, the Tasman, the country's longest glacier, has melted back into a young lake where boats weave between slabs of blue-white ice close enough to put your hand on. Then the light goes: the high snowfields flare pink and orange for a few minutes while the valley floor is already in cold shadow, and then the mountain goes dark and the sky above it does not. There is almost no light for hundreds of kilometres, and both Magellanic Clouds — our neighbouring galaxies — stand out plainly over a peak that, in the telling, came down out of that same sky in a canoe.

Worth knowing

Good to know

Come to the lakes at first light — the peak only mirrors on the water when the air is dead still, and the wind that ruffles it usually rises by mid-morning.
A moonless night shows far more than a bright one — check the moon phase before you travel, bring a red-light torch to protect your night vision, and give your eyes twenty minutes to adjust.
Alpine weather turns within the hour — carry a windproof layer and warm clothing even on a bright summer walk, as cloud and cold can close over the valley without warning.
Kea, the world's only alpine parrot, patrol the car parks — these bold, curious birds pry at rubber trim and unattended bags, so keep gear packed away and never feed them.
Mount Cook Village is the only base inside the park, and its handful of beds fill months ahead — book early, or visit for the day from Twizel or Lake Tekapo.

Things to do

1
Cross the three swing bridges up the Hooker Valley
The track is flat almost the whole way, so the work is in the distance and the wind rather than any climbing, and it crosses the braided river three times on bridges that swing under your feet. Nothing shelters it: you are walking bare moraine the Hooker Glacier stood on a century ago, and the weather up here turns inside an hour. Leave nothing loose at the car park — the kea there pull at rubber trim and open unattended bags.
2
Drive the length of Lake Pukaki
The road into the park runs the length of Lake Pukaki, with the water on one side and Aoraki growing steadily larger ahead of you. Pull-ins along the shore look straight up the lake to the peak, and on a still morning the whole mountain is mirrored in water coloured milky turquoise by rock the glaciers upstream have ground to powder. The colour is strongest under overcast light, not sun.
3
Cruise the Tasman Glacier's iceberg lake
The Tasman is New Zealand's longest glacier, and its meltwater has filled a young terminal lake dotted with icebergs. Small boats weave between the floating slabs of blue-white ice, close enough to touch, beneath the grey wall where the glacier still calves.
4
Watch the summit flush, then read the southern sky
As the sun drops behind the range, Aoraki's high snowfields flare pink and orange for a few short minutes while the valley floor has already fallen into cold shadow. Then the sky takes over: with almost no light for hundreds of kilometres, the night here turns dense with stars. Guides and small observatories point out the Southern Cross, the two Magellanic Clouds — our neighbouring galaxies — and the Milky Way's bright core arching overhead.
