The falls are named after the property of George Maxwell, an early settler who named his homestead Lesmurdie after his birthplace in Scotland.
The park's geology features laterite capping, which is common throughout the Darling Scarp.
Lesmurdie Brook is one of the few permanent watercourses in the area, though flow volume fluctuates significantly with the seasons.
The site acts as a critical wildlife corridor connecting the Darling Scarp to the Swan Coastal Plain.
Lesmurdie Falls National Park is located on the Darling Scarp, featuring a series of cascades on Lesmurdie Brook that drop 50 meters into the valley below. The park provides panoramic views of the Swan Coastal Plain and the Perth skyline. Visitors can access a network of trails ranging from the easy Falls Walk to the more challenging Valley Loop. Native vegetation includes jarrah and marri forests, which provide habitat for local fauna such as bandicoots and various bird species. The area is part of the larger Mundy Regional Park managed by the Western Australian Department of Biodiversity, Conservation and Attractions. The falls are a seasonal feature, relying on winter rainfall to maintain water flow. Picnic facilities and viewing platforms are situated at both the upper and lower levels of the site. Interpretive signage along the paths provides context regarding the geology and ecology of the Darling Range.
The upper viewing platform provides a wide-angle perspective of the waterfall with the Perth cityscape in the background.
Stick to the marked trails to prevent erosion and avoid private property boundaries.
Wear footwear with high-traction soles, as the rocky granite slopes become slippery when wet.
Carry adequate drinking water, as there are no potable water taps available within the park boundaries.
Attempting to climb the rock face adjacent to the falls, which is unstable and poses a significant safety risk.
Stay on designated paths to protect fragile flora; keep dogs on a leash at all times; remove all rubbish as there are no bins on site.
