Discover the modern-day relatives of some of the planet’s oldest life forms, the thrombolites, at Lake Thetis in Cervantes.
These rounded, rock-like structures may seem unremarkable at first glance, but they are closely related to stromatolites, some of the earliest known organisms on Earth. The Lake Thetis thrombolites are estimated to be over 3,500 years old.
Located just a 5-minute drive from RAC Cervantes Holiday Park, Lake Thetis is also accessible via a bush walk from Thirsty Point to Hansen Bay, which includes a detour past the lake. Once there, follow the marked boardwalk to view the thrombolites up close to ensure these fragile organisms are protected.
For those keen to explore further, a 1.5-kilometre loop trail circles the wetlands of the lake, offering opportunities to spot resident waterbirds and migratory shorebirds that frequent its shores.
Facilities at Lake Thetis are minimal, with only a few picnic tables near the car park. Be sure to bring any essentials, including water and sun protection, for your visit.
