Many years ago in the geological history of the area, the Murray – Sunset National Park was submerged beneath the sea.
With the withdrawal of these ancient seas what is left are sand ridges and dunes and a variety of vegetation including grasslands, saltbush and mallee eucalypt and myriads of wild flowers in Spring.
A feature of the park are the saltwater Pink Lakes which are especially remarkable when viewed at sunset.
The park also some bigger inhabitants including the red kangaroo shown. Both red and grey kangaroos are found in the park as well as wedge tailed eagle and emus.
The Pink Lakes – Lake Hardey and Lake Crosbie – of the Murray-Sunset National Park, change in colour throughout the year from a deep pink to a glistening white. The lakes take on this color due to an algea present in the lake and the white salt bed of the lake itself. Particularly after rains and when nutrients are washed into the lake the algea grows and the pink colour is the most intense.
