Hutt Lagoon is a saltwater lake located in Western Australia, about 5 km north of the town of Gregory. It covers an area of about 70 square kilometers and is known for its pink hue, which is caused by the presence of a type of algae called Dunaliella salina.

The lake's pink color can vary in intensity depending on several factors, such as the time of day, weather conditions, and the concentration of the algae. The best time to see the lake's vibrant pink color is during the middle of the day when the sun is at its highest point.

Apart from its unique color, Hutt Lagoon is also known for its salt production. It is one of the largest producers of salt in Western Australia and is home to a commercial salt harvesting operation.

Visitors can take a scenic drive around the lake to see its pink color and the stunning views of the surrounding landscape. There are also several lookout points and picnic areas along the way. Additionally, visitors can take a guided tour of the salt harvesting operation to learn more about the process of producing salt.
