Lake Matheson is nestled in ancient forest and is famous for mirror views of Aoraki/Mount Cook and Mount Tasman. Its excellent reflecting properties are due to the dark brown colour of the water – the result of organic matter leached from the humus of the forest floor. Dawn and dusk are the best times to enjoy the reflections in the lake. Shorter option: Car park to Jetty Viewpoint. Time: 40 min return car park to jetty. Distance: 1 km return car park to jetty.
