Haupapa/Tasman Glacier Track (2.7km) is one of the easier walks in Aoraki/ Mt Cook National Park. The drive towards Tasman Lake is stunning. The grand views of Mt Johmson, The Armchair, Nuns Veil and several more just before crossing the Hooker River bridge is spectacular. The drive continued along Mt Wakefield to a car park.
From the car park, it is a gradual climb through a series of steps. With elevation gain, the Blue Lakes became visible, nestled at the base of the mountains. They were glacial lakes with a blue tinge. The blue, in earlier days, were glacial melt-waters permeating through moraines. Over time, the glacier height dropped and water flow diminished. With rain water, algae developed and turned the colour green.
Towards the top, the track is rocks and debris left behind when the glacier retreated. Today, Tasman Glacier is 27km, the longest in New Zealand. It has retreated significantly since late 1990s. That’s when the lake was formed. At this height, the snow and ice covered mountains which included Mt Cook, Mt Tasman, The Alcolyte and Nuns Veil were stupendous.
The fractured appearance of Tasman glacier’s terminal face, the dirt covered glacier head, the turquoise lake and the braided Tasman River (joined by the Hooker River) leading towards Lake Pukakai in the south, is quite a sight. Yes, the suggested walking time is 45 minutes. However, be prepared to linger much longer, in the cold, as the views here are quite captivating. Imagine, this lake was only created 20 years ago. Sadly, Tasman Glacier’s terminal face may retreat further with rise in temperature. Go now!
