Drive McLaren Vale yourself, with a GPS audio guide that plays automatically as you go. Your booking unlocks the whole region in the free Wine Trails app: pick your date and starting point — McLaren Vale Township, Willunga, the coast, or straight from Adelaide — choose the cellar doors you want, and the app builds your personal route with turn-by-turn narration. 116 narrated stories cover 78 cellar doors and the people behind them: as you pass Kay Brothers at Amery you'll hear how Herbert and Frederick Kay planted Block Six Shiraz into sandy loam in 1892 — and those same vines are still cropping today. No group, no schedule, no guide — pause for a long lunch, double back, replay anything, and the audio keeps working when the signal drops, so Blewitt Springs' patchy coverage never matters. You'll need a car and a designated driver; tastings are booked and paid directly with the wineries.
