Formerly known as the Busselton-Flinders Bay Rail Trail, the Wadandi Track is a partially complete rail trail in the Leeuwin-Naturaliste region of Western Australia. The track is situated on the alignment of the 108 km railway that once linked Busselton to Augusta.

Two sections of the track are currently open – Busselton Jetty to Carbanup River (which is mainly asphalt), and Cowaramup to Vlam Road (which is mainly gravel).

Busselton Jetty to Carbanup River (16.4 km)

The northern part of the trail begins near Busselton Jetty, the longest timber-piled jetty in the Southern Hemisphere. The official northern trailhead is at Railway House, which houses the historic Ballaarat Engine, the oldest surviving Australian-built locomotive.

Leaving the Busselton Jetty precinct, the track heads west, following the original railway alignment along the Geographe Bay foreshore. The trail crosses the bridge at the Vasse River Diversion before turning inland near the Busselton Health Campus. The route continues through the Broadwater Nature Reserve wetlands before turning west to run parallel to the Busselton Bypass.

The trail enters the residential village of Vasse to meet the next trailhead. Just west of Vasse, the trail transitions from asphalt to gravel and continues west to Carbanup River near the site of the former Marybrook siding.

The section between Carbanup River and Cowaramup is yet to be developed.

Cowaramup to Vlam Road (37.3 km)

The southern part of the trail begins at the corner of Memorial Drive and Sunset Drive in Cowaramup. Heading south toward Margaret River, the trail winds through a bushland corridor and crosses several creeks. Just north of Carters Rd the trail provides access to the Margaret River MTB area.

After crossing Carters Rd the trail passes along the western side of Margaret River. The town centre can be reached along Turnbridge St or the cycleway on Wallcliffe Rd.

South of Margaret River the trail passes through forest, scrub and open farmland before arriving the small town of  Witchcliffe.

While the official southern trailhead is currently at Calgardup Rd, the railway alignment can be traced along Harrison Rd and Boulter Rd all the way to Vlam Road.
