The Stunning Geography Of Milford Sound: Rocks, Rivers & Glaciers

Milford Sound/Piopiotahi is known for its gorgeous landscapes, from its rocks to its glaciers. The geography of Milford Sound promises awe-inspiring sights that are a must-see and must-visit.

Here at Southern Alps Air, we have been providing scenic flights to Milford Sound for over 40 years. In fact, when it comes to the rocks, rivers, and glaciers of Milford Sound, here is what you need to know:

How Was Milford Sound Formed?

Over 600 million years ago, Milford Sound and the surrounding Fiordland National Park were part of a large mountain range. Over time, both Milford Sound and Fiordland were reshaped naturally, particularly through erosion and tectonic activity.

Despite its name, Milford Sound is not actually a sound – so, why is it called Milford Sound?

Early settlers incorrectly named the area a sound, though the area was actually formed by the erosion of glaciers, creating a fiord.

What Can You See in Milford Sound?

You can see numerous types of rocks in Milford Sound, including diorite, granite, gneiss (garnet crystals), and greenstone/jade. Greenstone deposits, as well as other interesting features of Milford Sound, can actually be seen from above on a flyover, which is why locals and tourists alike choose scenic flights to visit the sound.

Mitre Peak/Rahotu is situated on the shore of Milford Sound, standing at an impressive 1692 metres above sea level. With a fly-cruise-fly tour, you have the opportunity to both fly over and sail across the sound itself.

Is Milford Sound A Wonder Of The World?

Milford Sound is famous for its stunning scenery, from its glaciers to its waterfalls, making it undoubtedly one of the most breathtaking places in the world. It has even been touted as the ‘eighth Wonder of the World’ by Rudyard Kipling, author of the Jungle Book.
