Lesmurdie Falls

Lesmurdie Falls National Park is a small but spectacular reserve on the Darling Scarp, just 22 km from Perth city centre, protecting the most accessible waterfall in the Perth metropolitan area. Lesmurdie Falls plunges 37 metres over the Darling Fault escarpment, surrounded by jarrah forest, creating a picturesque natural attraction that has been enjoyed by Perth residents for generations. The park encompasses the falls and surrounding jarrah-wandoo woodland on the scarp, offering short walks and picnic opportunities in a forest setting close to the city. The falls are most impressive in winter and spring when seasonal flows are strongest.

Lesmurdie Falls National Park supports wildlife typical of the Darling Scarp. Western grey kangaroos, brushtail possums, and echidnas are present in the jarrah forest. The forest red-tailed black cockatoo and carnaby's black cockatoo visit to feed on marri seeds. Azure kingfishers and white-faced herons hunt along the creek below the falls. Western rosellas, spotted pardalotes, and honeyeaters are resident birds. The seasonal waterway below the falls supports aquatic invertebrates and provides water for forest wildlife. The park's proximity to urban Kalamunda means it experiences high visitor numbers.

Jarrah (Eucalyptus marginata) and wandoo (Eucalyptus wandoo) woodland dominate the park, with marri on lower slopes. The understorey includes native clematis, acacia shrubs, and a seasonal wildflower floor from August through October. The creek vegetation below the falls includes flooded gum and paperbark. Granite outcrops support specialised rock-dwelling plants. The falls themselves create a microhabitat of enhanced moisture that supports ferns and other moisture-loving species in the spray zone.

The falls descend over the Darling Fault Scarp — the major structural boundary between the ancient Yilgarn Craton plateau and the younger Swan Coastal Plain. The falls' character is determined by the resistant Archaean granite that forms the scarp edge. The waterway has cut back into the scarp over millennia through a process called headward erosion, gradually extending the gorge upstream.

Modified Mediterranean climate — rainfall 750–850 mm. The falls run strongly July–October after winter rains and reduce to a trickle in late summer. Spring (August–October) is ideal for full falls and wildflowers. Summer visits see reduced or no falls flow.
