What to expect
Expect forest walking on variable terrain with creek crossings and occasional wet sections, particularly in cooler months. The route is signposted throughout but navigation demands attention over long distances. Shade is generally good under native forest canopy, though some sections may be more exposed. Elevation change is moderate but sustained over the full distance; pace slows considerably on day two and three.
Good to know
- Waymarked route
Carry substantial water supplies and food; creeks are not reliable water sources year-round. Spring (Aug–Oct) offers mild weather and wildflowers. Summer heat and bushfire risk make winter to early autumn safer. Wear sturdy boots and gaiters for creek work. Plan accommodation or camps before starting. Check local conditions with Collie visitor information; some sections may be affected by logging operations or seasonal closures.
