Napa County, California

Napa County is all about the wine. Seriously, it’s everywhere. The Napa Valley is gorgeous, with rolling hills covered in vineyards. St. Helena and Yountville are like fancy postcards come to life.
The population is around 140,000, but the number of visitors far exceeds that. Remember that the charm here is in the details: the winding roads, the historic wineries, and the quiet moments overlooking a vineyard at sunset.
Popular spots are Robert Mondavi Winery and Beringer Vineyards. The whole place is pretty pricey, but hey, that’s what you get in Wine Country.
