The Town of Danville[11] is located in the San Ramon Valley in Contra Costa County, California, United States.

It was first a railroad that has been converted to an 80-foot-wide (24 m)[citation needed] corridor of bike and hike trails as well as controlled intersections.

[14] Danville is also home to the Eugene O'Neill National Historic Site, Village Theatre and Art Gallery, and the Museum of the San Ramon Valley.

[15] Often referred to as the "Heart of the San Ramon Valley", Danville was first populated by Native Americans who lived near creeks and camped on Mount Diablo in the summer.

Initially a farming community, the Town of Danville switched from wheat to fruits and nuts after the Southern Pacific Railroad built a spur line through the area in 1891.

The Union Academy, a private high school begun by the Cumberland Presbyterian Church, served the county from 1859 to 1868, until it burned down.

Developments such as Montair and Cameo Acres were built, the water and sewer districts extended their boundaries, and the new I-680 freeway which cut through Danville in the mid-1960.

Camino Tassajara is the main thoroughfare for east–west travel, most importantly to reach the eastern subdivisions far from the interstate.

Winters are rainy, but periods of several days to a week of mild, dry, sunny weather are quite common even in midwinter.
