Drive Enjoyment
This road features 5-star pavement but the score is downgraded to 4 stars due to rare occurrences of a small amount of gravel debris along the eastern portion near Berryessa, estimated to occur around 10% of rides in this rider's experience. Otherwise excellent road quality; no pott holes, appropriate banking, and both tight and more leisurely twisties. Very light traffic except at the western edge where traffic is light-moderate due to visitors to the vineyards.
Tourism Opportunities
Both St. Helena and Winters have gasoline, service, and food/drink available. At the west end, consider visiting one of the many world class vineyards of Napa Valley (Frog's Leap, Beringer, Silver Oak, etc.).
