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. 

Overnight Stops

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.

Great trail. Potters to about 8km in is great but from there it becomes very overgrown for at least 5km. That bit is not fun!. The last 3km or so to the camp is gorgeous. The hikers camp is fabulous, clean and in a stunning location.

Due to a heavy handed burn 2 years ago on this tourism attraction, the jarrah forest understory is just overgrown soap bush. The trail is wildly overgrown and unmaintained with bushes overgrowing the track and many small trees fallen over the track.

Two km south of the campsite the jarrah forest finally returns to the natural healthy understory that it's supposed to have with moss and ferns and a multitude of plant varieties.

The campsite also seemed unmaintained with the beautiful campsites slowly returning to the forest, the toilets without toilet paper, and a small shrub growing in one of the shelter footings.

The burning of this resource was a sad waste of taxpayer money.

Absolutely love this trail. One killer hill about 7 km from Potters Gorge, but the rest was quite manageable. A lot of the time you are walking with the bush on one side and views over the dam on the other. I was particularly impressed with the huge grass trees up the Potters Gorge end. The overnight campsite is in a very pleasant location over looking the dam

Trails are free and bring so many benefits to our community by providing opportunities to have fun, get fit, socialise, explore and challenge yourself. But they also have to be managed and maintained which only is made possible through terrific sponsors, donations and/or volunteering.
