Jarrah Forest and River Valley Country in Beelu National Park

Overview

Beelu National Park sits in the Darling Range east of Perth, in the Perth Hills around Mundaring. Formerly known as Mundaring National Park, it protects a stretch of hills forest and the Helena River valley, where jarrah and marri woodland meets granite country and watercourses running down from the scarp.

What gives the park its character is that mix of upland forest, steep valley slopes and broad views across the Mundaring Weir area. It feels close to the city, yet the landscape is very much that of the inland hills, with dry woodland, rocky ground and seasonal bursts of wildflowers.

Highlights

The big draw here is the scenery of the Helena River valley below Mundaring Weir. Much of the park is shaped by the folds of the Darling Range, with forested ridges dropping into the valley and opening out at lookouts over the lake, the river corridor and the surrounding hills.

The vegetation changes with the landform, which adds a lot to the park’s visual appeal. Jarrah and marri dominate across much of the woodland, while granite areas carry wandoo, and the lower valley floors support blackbutt and flooded gum. In spring, these hills are brightened by wildflowers among the grasstrees and open forest understorey.

Best Time to Visit

Spring is one of the best times to be here, when wildflowers are out and the forest has its freshest colour. The cooler months more broadly tend to suit walking best, especially when the hills and valley feel greener and the views are clearer.

Summer can still be striking for its dry bush character, but the park’s woodland and exposed slopes generally feel at their most inviting from late winter into spring.

Plants and Animals

Beelu National Park is a classic Perth Hills forest landscape, with jarrah, marri, wandoo and grasstrees featuring strongly through the park. Around granite and valley-floor areas, the plant communities shift again, which is part of why the scenery never feels one-note.

Native wildlife and birdlife are part of the park’s everyday character rather than a rare event, especially in the quieter woodland and along the river valley. The combination of forest, tributaries and varied terrain supports a broader mix of habitats than you might expect so close to Perth.

Culture and Heritage

The park’s name recognises the Beelu people, whose district was generally bounded by the Helena, Swan and Canning rivers. Their winter camps were in the Mundaring and Kalamunda hills, and the name relates to the Noongar word for river or stream, fitting a park shaped by the Helena River and its tributaries.

The area around present-day Mundaring Weir was also an important meeting place for Noongar families, linking the park’s landscape with a much older cultural history than its modern name suggests.
