Lake Amadeus is a salt lake located in the Northern Territory of Australia, about 50 km northwest of Uluru (Ayers Rock). It is one of the largest salt lakes in the country, stretching over an area of approximately 1,150 square kilometers. The lake is named after French Emperor Napoleon Bonaparte's wife, Empress Amadeus, by the explorer Ernest Giles who was the first European to discover the lake in 1872.

One of the most unique features of Lake Amadeus is its bright pink color, especially visible during the morning and evening light. The pink hue is caused by the presence of algae and bacteria that thrive in the hypersaline environment of the lake. Due to its high salt concentration, the lake is almost entirely devoid of any plant or animal life, except for a few salt-tolerant organisms.

The lake is a significant site for the local Pitjantjatjara and Yankunytjatjara indigenous people, who have been living in the area for thousands of years. They believe that the lake was created by the mythical serpent king, Wanampi, and that it has spiritual significance as a source of life-giving water during times of drought.

Visitors can access the lake via a dirt road from the nearby Lasseter Highway, and there are several lookout points that offer stunning views of the lake and its surroundings. Due to its remote location and harsh environment, visitors are advised to come well-prepared with plenty of water, sunscreen, and suitable clothing and footwear.
