Aka The Pink Lake, near Port Gregory, WA. Hutt Lagoon is Australia’s Most Unique Lake
Hutt Lagoon, or the “Pink Lake,” is a marine salt lake in Western Australia, famous for its vibrant pink color caused by the Dunaliella salina algae and high salt content
When we arrived the lake was a beautiful pink colour. Then the wind got up and the colour disappeared. Thankfully, the wind dropped away.

I would love to get over to WA one day and see this lake
WA has a lot to offer, but so does the east side.
