Along the trail
The Wiilman Bilya is a dedicated walking trail, stretching 87 kilometres in a loop that starts and finishes in the town of Collie. It combines sealed dual-use paths with a mix of dedicated single-track forest trails and minor vehicle tracks. To the south of Wellington Dam the trail uses part of the Bibbulmun Wellington Spur Trail.
The Wiilman Bilya trail will take you from Collie through Westralia Conservation Park and Wellington National Park to Wellington Dam, providing sweeping views of the Collie River valley and wide expanses of water. Imposing granite outcrops and the scents and sounds of the magnificent yarri (blackbutt), marri and jarrah forest along with wildlife encounters offer an unforgettable experience.
The Wiilman Bilya is a Class 4 walking trail with some steep gradients and unstable or slippery surfaces. A good level of fitness is recommended. The complete trail is a 5-day, 4-night walk. You can also break it up into shorter sections and do a day walk or an overnighter.
The trail is marked by a footprint motif on grey posts.
Make sure to purchase the detailed 'Walk the Wiilman Bilya Trail' map from the Collie Visitor Centre before commencing your journey.
The Wiilman people are known and acknowledged as the traditional owners of the land and waters through which the Wiilman Bilya trail passes.
There are four purpose-built campsites along the trail. Each features a large, roofed shelter (as shown in the image above) with weather-side walls, a water tank and a sealed vault drop toilet situated away from the shelter. Tank water is not guaranteed and must be treated before use. Use tank water sparingly and keep an emergency supply of drinking water as backup. Tank water should be treated by boiling, mechanical filtration, or chemical treatment.
Camping at Potters Gorge Campground requires a prior online booking (fees apply). Go to parkstay.dbca.wa.gov.au
If staying overnight at the Bibbulmun Track Arcadia Campsite in a group of 8 or more people, a Group Notification Form must be completed. See the Bibbulmun Track Foundation website for more information.
Parking is available at both ends of the trail and contact the Collie Visitor Centre to organise track transfers.
