The Thrombolites of Lake Clifton

While at uni I studied them, and in my working life I have even done investigations on the water chemistry of the lake and how it may impact them, yet I have never visited the thrombolites at Lake Clifton, just over an hour south of Perth. On my drive back from an Easter break, I thought why not take a break from the traffic and stretch my legs, as well as a toilet stop without a crowd.

There’s a boardwalk out over the thrombolites which is easily accessible for all, with lots of information signs about the microbiology of the organisms. Yes, that’s right they are living organisms not rocks like they appear.

For something that has taken me so long to see for the first time, I will definitely go back for a day trip and venture out on some of the longer walk trails on offer at Yalgorup National Park.

The Important Stuff


The site is managed by the Department of Parks and Wildlife (DPaW).


There are picnic tables and toilets at the main carpark with a wheelchair accessible boardwalk out to the thrombolites. There are other hiking trails to explore and the Cape Bouvard Winery is right next door if you want something more substantial to eat or drink.


The thrombolites are located in the Yalgorup National Park, east of Lake Clifton at the end of Mt John Road. There are signs to follow from Old Coast Road.

I visited in mid-April, water levels were low so the thrombolites were above the water line. Being located on the eastern side of the lake can result in some strong (cold at times) winds, so pack accordingly.
