Lake Tyrrell is a salt lake located in the Mallee region of north-west Victoria, Australia. It is approximately 320 kilometers northwest of Melbourne, near the town of Sea Lake. The lake is known for its stunning pink and gold sunrises and sunsets, as well as its natural mirror-like reflection when it is filled with water.

Lake Tyrrell is the largest salt lake in Victoria and covers an area of around 20,860 hectares. The lake is shallow, with an average depth of only about 30 centimeters, and is fed by a number of small creeks and drainage channels.

The lake's high salt concentration and flat surface make it a unique landscape, with many visitors attracted to its otherworldly appearance. In recent years, Lake Tyrrell has become a popular destination for astrophotographers, as the clear skies and low levels of light pollution make it an ideal location for capturing stunning images of the Milky Way.

Visitors to Lake Tyrrell can take a guided tour or explore the area on their own. The best time to visit is during the dry season (April to October), when the lake is most likely to be dry and the surface is hard enough to walk on. It is important to note that visitors should not enter the lake when it is filled with water, as the salt concentration can be harmful.
