Milford Sound is a sight to behold. Breathtaking. It sits within Fiordland National Park, part of UNESCO World Heritage Site, Te Wāhipounamu – South West New Zealand. It is the best known of New Zealand’s fiords. The Māori name for Milford Sound is Piopiotahi, a long-extinct native bird – the piopio. It is from here that the ancient Māori would collect precious pounamu (jade/greenstone). What is a fiord? They’re long and narrow inlets to the sea with steep cliffs, which were gouged out by glaciers a few thousand years ago. When the ice melted the sea water rushed in forming these spectacular landscapes. Viewing the fiord by boat you can see some of the deep scratches left by retreating glaciers. The dark waters are home to normally deep-sea dwelling creatures (Te Ara: The Encyclopaedia of New Zealand).
