The Mundaring Weir Rail Trail is a 7-kilometre route through the scenic landscapes of Beelu National Park in Western Australia. This grade 3 hike typically takes around three hours to complete, following the path of a former railway that once played a vital role in the region’s history. Starting opposite the historic Mundaring Weir Hotel, the trail also forms the first section of the renowned Munda Biddi Trail, a long-distance cycling route stretching to Albany.
As you make your way along the track, you'll pass through sections of the Zamia State Forest and Beelu National Park, where the terrain varies between compacted earth and coarse to fine gravel. The trail is mostly flat and undulating, with occasional steep sections where it deviates from the original railway formation. These changes in elevation add a sense of variety to the walk, rewarding hikers with views over rocky outcrops, pockets of native bushland, and small waterfalls that flow after heavy rain. Wildlife is abundant in this area, with birdsong filling the air and the chance to spot kangaroos, echidnas, and other native species along the way.
One of the most significant features of the landscape is the Golden Pipeline, a 560-kilometre engineering marvel that transports fresh water from Mundaring Weir to Kalgoorlie. Constructed between 1898 and 1903, this pipeline remains the longest freshwater pipeline in the world and continues to supply water to communities along its route. It was the vision of Western Australia’s Government Engineer-in-Chief, C.Y. O’Connor, whose pioneering work transformed the region. At the No. 1 Pump Station, located at the end of the trail, visitors can explore interpretive displays that delve into O’Connor’s legacy and the incredible feat of engineering that made the pipeline possible.
The trail itself gently descends from Mundaring to the weir, offering a relaxed walk that is suitable for most hikers, though some steeper sections may require extra care. At its northern end, the Mundaring Weir Rail Trail connects with the Railway Reserves Heritage Trail, creating opportunities to extend the hike for those wanting to explore more of the area’s rich history and natural beauty. Whether you're drawn to the region’s engineering past, its diverse landscapes, or the peaceful bush setting, this trail offers a rewarding and immersive experience within easy reach of Perth.
