Lake Clifton is a unique and ecologically significant lake situated within Yalgorup National Park, located just south of Mandurah in Western Australia — roughly 18 miles from the nearest major city. The park encompasses approximately 13,140 hectares and is home to ten lakes that together form an internationally recognized Ramsar wetland system of global importance. Lake Clifton is perhaps best known not for its fishing, but for its remarkable thrombolites — ancient, rock-like structures built by living microorganisms that represent some of the earliest forms of life on Earth. This extraordinary ecological context shapes the character of the lake and the experience of visiting it, making it a destination unlike any other in Western Australia.
