Natural Wonder: Lake Hillier, Australia


Lake Hillier is an amazing pink lake on Middle Island, in the Southern Australia. It’s believed that the water’s pink colour is due to the extremely high level of salinity. This discovery was made as early as 1802, but there has been no definitive proof that salt is the source of its unique hue.

The lake is separated from the Southern Ocean by a thin strip of sand. Measuring just 600 metres wide and shaped like a footprint, this relatively small feature has a huge impact when viewed from a scenic flight or cruise. 

Located on Middle Island, the largest of the Recherche islands (11 kilometres from the coast of Cape Arid National Park), this striking phenomenon can be accessed by chartering a plane or boat with nearby tour operators in Esperance.
