Nambung National Park also contains beaches at Kangaroo Point and Hangover Bay, as well as coastal dunes and flowering plants in low heathland areas. A boardwalk in the northern area of the park at Lake Thetis allows visitors to view thrombolites which, like stromatolites, are structures built by micro-organisms, especially cyanobacteria. Some of the fossilized thrombolites have been dated to 3.6 billion years old. The Pinnacles Desert Discovery Centre features exhibits about the geology of the pinnacles formations and the cultural and natural heritage values of the area.
