This is the index to two rides in Sonoma County - and one that crossed from Marin County to San Francisco.
The rides are selected by clicking on the appropriate ride name on the lowest menu bar above.
This was the first time that I'd visited the wine country around Sonoma and Napa. I stayed in Santa Rosa and found that the Santa Rosa's Bike Club's web site was an invaluable source of information about rides in the area. The area also benefits from the availability of two quality bike maps.
