context_page_description: Napa County is a county north of San Pablo Bay in the northern portion of the U.S. state of California. As of the 2010 census, the population was 136,484. The county seat is the City of Napa. Napa County was one of the original counties of California, created in 1850 at the time of statehood. Parts of the county's territory were given to Lake County in 1861.
  Napa County comprises the Napa, CA Metropolitan Statistical Area, which is also included in the San Jose-San Francisco-Oakland, CA Combined Statistical Area. It is one of four North Bay counties.
  Napa County, once the producer of many different crops, is known today for its regional wine industry, rising to the first rank of wine regions with France by local wineries Stag's Leap Wine Cellars and Chateau Montelena winning the "Judgment of Paris" in 1976.
context_section_description: According to the U.S. Census Bureau, the county has a total area of 789 square miles (2,040 km²), of which 748 square miles (1,940 km²) is land and 40 square miles (100 km²) (5.1%) is water.
  Napa is warmer in the summer than Sonoma County, to the west, or Santa Barbara County, a wine-producing county in southern California. Thus, the Napa wineries favor varietals such as Cabernet Sauvignon, while Pinot noir and Chardonnay are more the specialty of Sonoma and Santa Barbara wineries. At the north end of Napa County, in the Mayacamas Mountains, lies Mount Saint Helena, the Bay Area's second tallest peak at 4,344 feet (1,323 m) and home to Robert Louis Stevenson State Park; Snell Valley is also situated in northern Napa County; the Missimer Wildflower Preserve is within Snell Valley. On the west side of the Napa Valley is Hood Mountain, elevation 2,750 feet (838 m).
  Napa County is home to a variety of flora and fauna including numerous rare and endangered species such as Tiburon Indian paintbrush and Contra Costa goldfields.
