The Great Ocean Drive (Tourist Loop) from Esperance will take you past the Pink Lake. It has not been very pink for a while due to changes in the water after heavy rain - slowly recovering and hopefully will once again take on the famous pink colour. The pink is caused by a salt tolerant algae that is found in this lake - Dunalella Sailina and a bacteria called Halobacterium cutirubrum. Apparently the salt found in the Pink Lake is 99.9% pure.
There are a number of areas to park along this road and take pictures of this lake and it is worth spending some time driving this tourist loop.
We saw the pink colour in the Hutt Lagoon (near Geraldton) and it was quite spectacular (even on a cloudy day).
