Notarian nails it in his review. Fun group of roads. Keep on your toes for the wine tasters. Really nice area of California to explore by motorcycle.
Okay, you are heading south in search of good roads and youve taken Nacimiento/Fergeson Road to Fort Hunter-Liggit and G14 south past Lakes San Antonio and Nacimiento. About 6 miles past Nacimiento Dam youll come to Chimney Rock Road.
Turn right onto it and enjoy fine tarmac and undulating twisties for the next five miles. Then youll come to Adelaide Drive on the left. Take it and it leads to Vineyard Drive after about 3 miles.
Vineyard Drive is just that. Vineyards and wineries along the road. This section is more travelled than the first sections but a very pleasant way to wind yourself south to Hwy 46
There are a few interesting short rides off Chimney Rock and Adelaide such as Klau Mines Rd and Cypress Mountain Rd. Short but sweet if time to explore.
Wine money ensures the road conditions are maintained in good order.
