Lake Clifton Thrombolites: Earth's Ancient Life Forms

#perthonbudget • Vibe: Scientific and humbling. Observe rare, ancient (2,000-year-old) rock-like structures formed by micro-organisms, offering a glimpse into early life on Earth. • Location/Access: Located within Yalgorup National Park, approximately 30 minutes south of Mandurah via the Old Coast Road. Free entry, with a dedicated car park off Mount John Road. • Must-See: The Observation Boardwalk takes you over the water for close viewing of the largest lake-bound thrombolite reef in the Southern Hemisphere. • Best Time to Visit: January to May is optimal, as water levels are typically lower, exposing the rounded thrombolite domes for clearer visibility. • Trails: The site features the short boardwalk and the Lakeside Loop Trail (5km) for a longer walk through tuart and peppermint bushland. • Facilities: Limited, but includes an information shelter, picnic tables, and wheelchair-accessible toilets. No cafes or shops on site. • Tip: Thrombolites are critically fragile; stick strictly to the boardwalk to protect them. Bring insect repellent, especially around dusk.
