Lake Clifton Thrombolites

Lake Clifton Thrombolites are living rock-like microbial structures on the eastern shore of Lake Clifton within Yalgorup National Park, about 30 kilometres south of Mandurah in Western Australia. Forming the largest thrombolite reef in the southern hemisphere, they are modern analogues of some of Earth's earliest life forms. Visitors view the thrombolites from a dedicated boardwalk and observation platform with interpretive signage explaining their formation, ecology and conservation.

Visitors can expect a short timber boardwalk and observation platform extending over the shallow, hypersaline waters of Lake Clifton. Thrombolites appear as rounded, rock-like mounds visible just above or below the water surface depending on lake levels. The site is open and exposed with interpretive panels explaining the biology and geology. There is a small car park at the trailhead and no direct water access. The experience is quiet, educational and focused on observation and photography from the boardwalk.
