Gravel Road Touring in Napa Valley with a 4 year old

[j9fitzy]

Hi there,
We are looking for a 4 day cycling  trip in the Napa-ish CA area the last week in March.  We will be hauling our 4 year old kid in a wee-hoo trailer and we will have our Salsa Fargo's packed for camping.  We would love to stay on as much gravel/forest road as possible as to avoid cars with the little one.  We are looking for a route where we can camp, provision daily, and if weather got bad we can hit up a b&b or inn if possible.
I know this is a tall order but is there anyone that you can put me in touch with that might have an idea?
Thanks

Try looking at this site for bike maps north of San Francisco. They produce suitability maps so you can pick and choose the route you want. And I think the maps show gravel roads.

I am not aware of any significant gravel roads in Napa or Sonoma County, particularly for a four day trip. The roads in those counties are generally paved, small to no shoulders, and loaded with traffic, some of which are exploring the hundreds of wineries in those two counties. Of the two counties, Sonoma would be a better choice for biking (Alexander Valley, Dry Creek, Russian River) or, perhaps, Mendocino County (Anderson Valley).
