Located within Yalgorup National Park, just south of Mandurah, the ancient thrombolite reef at Lake Clifton offers a rare glimpse into Earth’s earliest days. These fascinating, rock-like formations are among the planet’s oldest life forms, dating back approximately 570 million years, producing oxygen that paved the way for all subsequent life.

The Lake Clifton thrombolites, around 2,000 years old, form the largest thrombolite reef in the southern hemisphere. From the boardwalk over the lake, you can observe these formations up close—especially between January and May, when low water levels provide the best view.

For a truly memorable experience, consider a guided tour to uncover the incredible history and cultural significance of these ancient wonders—a journey into the origins of life itself!
