Silverado Trail
Running parallel to the busier Highway 29, the 29-mile Silverado Trail is Napa’s quieter, more scenic eastern route. Originally a 1852 wagon trail built after flooding, it later served silver miners before becoming the backbone of one of the world’s most famous wine regions. Today more than 40 wineries line or sit just off this road, including legendary Stag’s Leap Wine Cellars — whose Cabernet helped put California on the global map at the 1976 Judgment of Paris.
