Famous for reflecting a near-perfect image of Aoraki Mount Cook in its waters, Lake Matheson was formed around 14,000 years ago when the Fox Glacier retreated from its last major advance towards the sea.
The glacier left a depression that later filled with dark ale-coloured water. Discolouring of this water was caused from leaching from organic matter on the ancient forest floor that surrounded this lake.
Five kilometres west of the Fox Glacier Township on the South Island's West Coast, Lake Matheson is situated within the Westland Tai Pountini National Park.
A tiny lake well protected from the wind, its waters often sit incredibly still, providing the perfect mirror for the mountains above (the view is best at sunrise and sunset).
An easy walk through the forest affords fantastic reflection views once you reach the lake – as does a walk on to the jetty, which takes you past tall kahikatea (white pine) and rimu (red pine).
It's worth taking a look at this reflection, and when you too are seeing double, you'll soon realise why Lake Matheson is considered to be a jewel in New Zealand's scenic crown.
