From Buandik Campground, follow the creek upstream on the signed Buandik Falls Walk. The falls are roughly 1.2 kilometres return, but the short distance can feel more involved than the number suggests because the route is a bush path beside uneven rock and water. Allow about an hour to walk carefully, look around, and take photographs. The campground and nearby picnic area are the practical starting points; this is not a roadside waterfall with a formal viewing platform.
The approach is part of the experience. Buandik sits in a remote corner of Gariwerd, and the final drive uses unsealed roads and tracks. The area also has nearby Aboriginal cultural sites, so follow signs, respect closures, and do not enter fenced or protected areas. Keep this waterfall visit separate from any longer walk you may add in the same valley.
