[5] 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.
