Heysen Trail

The Heysen Trail is Australia's longest marked walking trail and one of the most varied long-distance routes in the country. Stretching 1200km from Cape Jervis on the southern tip of the Fleurieu Peninsula to Parachilna in the northern Flinders Ranges, the trail traverses five distinct bioregions and an elevation change from sea level to over 1100m in the Flinders.

The southern sections through the Fleurieu and Adelaide Hills are domesticated by the Heysen's standards: rolling farmland, wine regions, and the Mount Lofty Ranges with predictable water and regular towns. The trail passes through the edge of the McLaren Vale wine region, skirts the foot of Mount Barker, and climbs through the native bush reserves east of Adelaide. These sections are accessible and can be done as multi-day day sections before committing to the full route.

North of Burra, the trail changes character. The mid-north sections cross private station land, and the trail is marked but the terrain is increasingly dry, the towns more distant, and the services less predictable. Camping on private property requires discretion and sometimes permission — the trail passes through a mix of public reserve and private pastoral land, and the ethics of access are worth understanding before relying on a map that doesn't show property boundaries.

The Flinders Ranges section from Melrose north is the physical and visual highlight. The trail climbs the main range face, traverses exposed ridgelines with 180-degree views over the inland plain, drops into gorges with ancient river red gums, and crosses the tilted geological spectacle of Wilpena Pound. The terrain here is rocky, loose in places, and demanding on tired legs in the later stages of a thru-run.

Water management in the northern sections requires planning. The Flinders Ranges section (Hawker to Parachilna) can have 40-60km between reliable sources. Station tanks are marked on the official maps but are not always filled — call ahead when possible.

Trail runners complete the route in 20-28 days. The season closes for the northern sections in summer: the Flinders above 30°C by November, and the mid-north water sources dry out by December. April-October is the safe window, with the trail closed in the southern sections (fire risk) between November-April in some years.
