Napa Valley Expo would be great if it is available. It has a limited number of sites and when I tried for late September, it was full. Found two sites at Vineyard RV Park in Vacaville. Tried two other parks closer to Napa, but they were also booked for the days we were wanting. Late September, early October seem to be very busy time in wine country.
