HIKING SEALY TARNS TRACK

Often called the ‘Stairway to Heaven’, the Sealy Tarns Track is a challenging alpine hike that rewards every step with some of the best panoramic views in Aoraki/Mount Cook National Park. With over 2,200 steps and a steep gradient, this is a track for those with good fitness, but the payoff is more than worth it.

Climbing high above the Hooker Valley, you’ll gain a bird’s-eye view over Mount Cook Village, Mueller Glacier, and all the way up to Aoraki/Mount Cook. At the top, the track levels out beside the Sealy Tarns — two small alpine lakes that perfectly reflect the towering peaks on calm days.

Getting There

The Sealy Tarns Track starts at the White Horse Hill Campground, about a 10-minute drive or a 45-minute walk from The Hermitage. This is the same car park used for the Hooker Valley and Kea Point tracks. Toilets and parking are available at the trailhead.

Walking The Track

The Sealy Tarns Track begins on the same path as the Kea Point Track, branching off after a short distance. From there, the climb begins, and it doesn’t let up. Over 2,200 wooden steps lead you steadily uphill through alpine scrub and tussock.

As you gain height, the views open up dramatically. Mueller Lake and the glacier below become clear, with Aoraki/Mount Cook rising beyond. Kea are often spotted in this area, so keep an eye (and ear) out.

At the top, the Sealy Tarns sit nestled in a high alpine basin. On a still day, the reflection of Aoraki in the tarns is unforgettable. Take time to rest at the viewing platform, soak in the scale of the landscape, and enjoy your well-earned achievement.

The track ends at the tarns — return via the same route.

Best Time Of Day To Walk

Clear mornings are ideal for this track. The light hits the eastern face of Aoraki and Mueller Glacier beautifully, and the cooler temperatures make the climb more comfortable.

Sunset is also spectacular, with golden light bathing the valley below — just make sure to allow enough time to descend before dark.

Best Time Of Year To Walk

Sealy Tarns is walkable most of the year, but late spring through autumn offers the best conditions. In summer and autumn, the track is usually snow-free and offers long daylight hours for walking.

In winter and early spring, snow and ice are likely, this can make the track slippery and much more difficult. Check conditions at the DOC Visitor Centre before attempting in colder months.

What To Bring

Although only a half-day hike, in these alpine conditions it is always best to come prepared.

Bring enough water to stay hydrated, especially in summer. A few light snacks will help keep your energy up for the climb.
Weather can change quickly in the mountains. Always pack a warm layer and a windproof jacket, even in summer.
The track is fully exposed to the elements. Sunscreen, sunglasses, and a hat are essential.
The track includes stairs, gravel and sometimes uneven ground. Hiking shoes or boots will give you better grip and support, especially on the descent.
You’ll want to capture the views, Sealy Tarns offers some of the best vantage points of Aoraki/Mount Cook.
