Summary

Lake Thetis Loop Trail is an easy, 1.5km walk around the shores of Lake Thetis. It is one of only a few places in the world with living marine thrombolites, or ‘Living fossils’. The first 300m of Boardwalk, which passes the best examples of thrombolites in the lake, is universally accessible.

Enjoy an easy 1.5km loop walk around Lake Thetis and gain an insight into what life was like at the dawn of time. Like the famous stromatolites of Hamelin Pool, in Shark Bay, these rock-like structures on the edge of Lake Thetis are built by micro-organisms too small for the human eye to see. Within the structures are living communities of diverse inhabitants with population densities of 3000 per square metre! The thrombolite-building micro-organisms of Lake Thetis resemble the earliest forms of life on Earth. The discovery of modern examples helped scientists to understand the significance of micro-organisms in the environment and unravel the long history of life on Earth. Today living examples of these once completely dominant organisms are restricted to only a few places.
