Drive Marlborough 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 — most people begin in Blenheim or straight off the Picton ferry, though you can start anywhere and the GPS will pick you up — choose the cellar doors you want, and the app builds your personal route with turn-by-turn narration. 85 narrated stories cover 48 cellar doors and the valleys between them: as you cross the Wairau plain you'll hear how this was sheep country until 1973, when Montana Wines pushed seventy-five thousand vine cuttings into stony ground every expert had written off as too cold, too windy and too far south for serious wine. No group, no schedule, no guide — pause for a long lunch, replay anything, and the audio keeps working when the signal drops. You'll need a car and a designated driver; tastings are booked and paid directly with the wineries.
