Lake MacDonnell: Australia’s Most Stunning Pink Lake

Lake MacDonnell stands out as one of the most mesmerizing. This striking pink lake, located on the Eyre Peninsula in South Australia, is a must-visit for nature lovers and photographers alike.

Lake MacDonnell is a salt lake on western Eyre Peninsula near the Nullarbor Plain. Situated 15 km south of Penong on the way to Point Sinclair. It is the site of a former salt mine and the largest gypsum mine in Australia, on the largest gypsum deposit in the southern hemisphere. The ore body consists of calcrete coastal dunes of the Pleistocene Bridgewater Formation in a 20-kilometre (12 mi) northwest-trending depression. The gypsum formed during the Holocene period. The gypsum deposit has a one-metre layer of gypsarenite containing 93 percent gypsum calcium sulphate. Below that is a 5-metre (16 ft) layer of selenite containing 94-96% calcium sulphate.

The Unique Beauty of Lake MacDonnell:

High in salt concentration, the lake gives the impression of a salmon pink lake on clear days. One side of the causeway is Pink Lake, the other side is Green Lake and further down over the small bridge is the Blue Lake. The Pink Lake is caused by salt loving algae called dunaliella salina and bacteria called halobacteria that secrete carotenoid red pigments, that turns the water bright pink. 

Lake MacDonnell is famous for its vivid pink color, which contrasts dramatically with the surrounding white salt flats and blue skies. The lake’s vibrant hue is a result of its high salt concentration, which fosters the growth of a type of algae called Dunaliella salina. This algae produces carotenoid pigments, giving the water its distinctive pink shade. The intensity of the color varies depending on weather conditions and water levels.

 

One of the most remarkable features of Lake MacDonnell is the “Watermelon Road”, a long, straight road that runs through the middle of the lake. On certain days, this creates a stunning effect where one side of the road appears pink while the other is a vivid blue or green due to differing salt concentrations.

 

How to Get There:

Lake MacDonnell is located near the small town of Penong, about 860 km west of Adelaide and 45 km from Ceduna. The best way to reach the lake is by car, making it an ideal road trip stop along the Nullarbor Plain. The drive from Ceduna takes around 45 minutes, and a four-wheel-drive vehicle is recommended for some of the rougher tracks in the area.

When people refer to the Nullabor they generally mean the huge area of deserted land. The striking pink waterscape separated from a neighbouring blue-green lake by a gunbarrel-straight dirt road is Lake MacDonnell, near Penong by the Nullarbor Plain. 

Best Time to Visit:

The best time to visit Lake MacDonnell is during summer and late spring, when the salt concentration is highest, and the pink hues are most vibrant. However, the color of the lake is subject to natural changes, so checking recent traveler photos or weather conditions before planning your trip is a good idea.
