About Napa County

Napa County was formed in 1850 as one of the original counties in California. Covering 789 square miles, Napa County is located in the northern region of the San Francisco Bay Area, with Sonoma County to its west and San Pablo Bay to its south.

Over the course of Napa County’s history, its natural resources and climate have greatly dictated its development. While gold was being prospected in other parts of the state in the 1850s, Napa County was a center for silver and quicksilver mining. In the mid-1880s, Calistoga was founded as a resort town to take advantage of the area’s numerous mineral hot springs. Following World War II, new businesses capitalized on the Mediterranean climate of the region with the rise of the wine industry and related tourism, and the trend continues today.

Summers in Napa County are marked by warm to hot, sunny days and cool nights. Winter is mild and is characterized by occasional rain and frost. It also has the benefit of having several microclimates that vary in temperature from one another, allowing a wide range of wine grape varietals to grow well in the area. 

Beyond its world-renowned reputation as a wine destination, other popular activities to enjoy in Napa County include fine dining, spa retreats, golf, ballooning, cycling, fishing, horseback riding, and more.   

We invite you to experience all of the excitement Napa County has to offer!
