Lake Clifton is a small town located on the east side of the lake of the same name in the Peel region of Western Australia just off the Old Coast Road, between Mandurah and Bunbury at the north end of the Yalgorup National Park.
Lake Clifton contains basic accommodation and shopping, and a community hall offering a range of activities. A couple of roadhouses for passing trucks and motorists are located on Old Coast Road, while rural residential estates have sprung up at Tuart Grove.
The Yalgorup National Park was established in the 1970s to protect the coastal lakes, swamps and tuart woodland in the area. The area is also central to waterbird migration patterns. At the edge of Lake Clifton, rock-like structures called thrombolites (similar to stromatolites) can be seen, built by tiny microorganisms believed to resemble the earliest forms of life on Earth. Scientists have suggested their presence here may be due to upwellings of fresh groundwater high in calcium carbonate. An observation walkway has been constructed to allow visitors to view these fragile structures.
