On the edge of Willunga, at the southern end of the McLaren Vale wine region, this hosted retreat takes a single couple at a time. The accommodation is self-contained but attentively looked after by resident hosts, who deliver multi-course breakfast hampers each morning and lend out electric bikes for the nearby Shiraz Trail, a rail-trail that links the district's cellar doors without a car. Interiors run to a comfortable sitting area, a bathroom with underfloor heating and a bed positioned for the garden outlook. Willunga is an old wheat-and-almond town of stone buildings and a well-regarded Saturday farmers' market, a short drive from the coast at Aldinga. The house has been a repeat winner in South Australia's tourism awards for hosted accommodation, and its appeal rests on that one-party-at-a-time intimacy rather than scale.
