Drive the well-signed Highway 29 for classic valley views, easy pullouts and straightforward lanes that accommodate larger vehicles while connecting key sights. St. Helena’s Main Street is a short, walkable stop for shops and tasting rooms, letting you leave your campervan parked while you explore on foot. Wineries such as Beringer and Charles Krug have historic buildings and grounds reachable by road, offering photo stops and tasting reservations for travelers. Scenic side roads off the main highway provide peaceful drives past vineyards and oak-lined hills that reward a slow, relaxed pace.
