It’s well worth visiting the remarkable Stromatolites at the picturesque Lake Thetis near Cervantes if you are in the area. Enjoy a walk around the lake and witness the earth’s oldest living life form, believed to be over 2,000 years old. Stromatolites are among the world’s oldest fossils, some of which are over 3.5 billion years old, and provide some of the most ancient records of life on Earth. They may look like rocks but they are in fact living things! You will find the best examples of Stromatolites at the south western edge of the lake, with a beach and bush walk trail available.
