Easy track
Starting from the car park off Hansen Bay Road, Cervantes, this walk takes you on a circuit around Lake Thetis. Lake Thetis is a lake that hosts thrombolites which are amazingly formed by cyanobacteria over billions of years. These organisms used to be very common, but there are only a handful of places you can see them currently. They are prominent examples of the earliest living organisms in the world and give an insight into the long history of life on Earth. There is also a picnic table towards the middle, which is suitable for walkers to have a small lunch looking over the open view the lake offers. The first 300m of the boardwalk is universally accessible; the texture is a hardened or compacted surface for the first half and is followed by a flat dirt track afterwards. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
