There is no loop, so arrange a pickup or other transport between the towns before you start. The Timboon trailhead is beside the swimming pool on Lambert Street; at the Port Campbell end, the trail starts by Desaily Street, with parking at the Recreation Reserve. Water is available at the Timboon station and Paaratte, and toilets are listed near the Timboon Ice Creamery and at Paaratte. Dogs are allowed on lead. The route is also used by cyclists, so expect to share the wide track.
If you want a shorter version, walk about 12 km return from Timboon to Schulz Organic Creamery & Café. It is on the route and makes a natural halfway turn-around for a shorter day.
