The Riesling Trail stretches thirty-five kilometres between Auburn and Clare, tracing a decommissioned railway corridor that once carried grain and ore through the mid-north wine region. Opened as a recreational trail in 1997, it follows telegraph poles and stone culverts built in the 1870s, passing through townships where German settlers established vineyards that now anchor South Australia's cool-climate wine identity. The walking path—sealed in some sections, gravel in others—connects more than forty cellar doors and offers walkers access to Polish Hill River, Watervale, and Sevenhill sub-regions without navigating vehicular traffic. Clare Valley walking tours today serve both self-guided walkers and participants in guided wine-and-trail packages. The trail's flat gradient and segmented layout allow visitors to complete sections between two and ten kilometres, with pickup points at Sevenhill, Leasingham, and Penwortham. Local operators offer luggage transfer, bike-and-walk hybrid itineraries, and winemaker-led walks that stop at boutique producers not open to drive-in traffic. The trail's cultural layer includes interpretive plaques marking Jesuit mission history, colonial flour mills, and indigenous Ngadjuri gathering sites. Walking the Riesling Trail exposes the valley's viticultural micro-geography in a way vehicle touring cannot. Walkers pass between rows of cabernet franc and grenache, witness soil transitions from terra rossa to slate, and observe elevation changes that influence grape ripening. The trail's design prioritizes accessibility—wheelchair-friendly segments run from Sevenhill to Clare, and rest shelters appear every three kilometres. Spring walkers encounter wildflower corridors and lamb-dotted paddocks; autumn visitors see harvest activity and taste young vintages at cellar doors that open directly onto the path.
