Drive Sonoma County 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 — Sonoma Plaza, Healdsburg, Santa Rosa or Sebastopol — choose the cellar doors you want from 76 across the county, and the app builds your personal route with turn-by-turn narration. 96 narrated stories cover the county's people and places: as you pass the Sonoma Plaza you'll hear how a flamboyant Hungarian who called himself Count Agoston Haraszthy founded Buena Vista east of the plaza in 1857, then returned from Europe with over 100,000 cuttings of 300 grape varieties and seeded an entire industry. No group, no schedule, no guide — pause for a long lunch in Healdsburg, 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.
