The 56 kilometre stretch includes a new 94 metre pedestrian bridge, taking the hiking experience for both residents and visitors to the next level.
The eastern portion of the trail winds through stunning jarrah, marri and yarri forests, providing spectacular views of Wellington Dam.
The new section can be linked with the Bibbulmun Track for a 4-day return hike from Collie. Overnight campsites are available and can be accessed by paddle craft from the dam.
When all sections are complete, the 87 kilometre trail will offer hikers a 5-day, 4-night experience that starts and finishes in Collie, circling Wellington Dam.
The trail is named after the Traditional Owners of the area, the Wiilman Noongar people, with the term Bilya meaning 'river' in the Noongar language.
The Kaniyang Wiilman pedestrian bridge offers stunning views of the Collie River. The concrete base displays artwork designed by local artist Natalie Veal, which highlights the connection between nature and culture of the region.
It's part of the $10 million Collie Adventure Trails initiative being delivered through the Department of Biodiversity, Conservation and Attractions.
