Some things get better with age! Located at Yalgorup National Park, south of Mandurah, the thrombolite reef at Lake Clifton offers you a glimpse of what life was like when the earth began.

These rock-like formations are found in only a few places in the world and scientists believe that thrombolites are one of the first life forms on earth, dating back approximately 570 million years, producing oxygen that made all subsequent life possible.

The Lake Clifton thrombolites are approximately 2,000 years old and the largest in the southern hemisphere. You can view them from above on a boardwalk over the lake with January to May being the best time to see them when the water levels are low.

The best way to experience the thrombolites is on a guided tour where you will learn the history and cultural significance of the thrombolites.
