Hiking the blue lakes and Tasman Glacier Track

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!

Tasman lake boat excursion

We stayed at the Hermitage Hotel. Due to Covid 19 travel restrictions, Kiwi’s have been travelling locally. Our hotel was near capacity. To encourage travelers to explore Aoraki Mt Cook National Park, prices for some excursions were reduced. This included Glacier Explorer – a boat ride on the Tasman Lake.

After a short drive to a car park (same starting point for the Blue Lakes and Tasman Glacier Track), we took a short walk on the moraine towards the chalky turquoise lake. After fitting on our life jackets and safety briefings, we were off. The water’s surface is cold. Surrounded by snow capped mountains including the looming Mt Cook, I was excited to see icebergs floating around. As we got closer, their sizes were enormous. The guides gave insights and short lecture on glacier-logy. These sculptured ice are several hundred years old. In the heat, water dripped rapidly. We even managed to break off some ice and taste. Cold but refreshing.

Tasman Lake is enormous. The view from glacier hike, the previous day, did not give the scale or enormity of the lake. We sped north towards the glacier’s terminal face. For safety, we viewed from a distant. The giant ice wall (4km wide) can calve without warning and cause tsunami like waves. A sharp sound burst through the silent and cold air. Then, followed by an ice wall breaking off and crashing into the water. It wasn’t big but the display was exciting.

Beyond the fractured ice face, the top of the glacier is covered with black dirt. It stretched towards the tops of the mountains. If fact, this dirt covering may extend the life of the glacier. Murchison Glacier is adjacent to Tasman Glacier. Perhaps the best overview would be aerial. Even better will be to walk (flights-and-tours ) on the glacier!

The overflow from Tasman Lake merged with Hooker River and the braided river flowed south towards Lake Pukaki.
