In the 1880's, Upper Lake had three livery stables. As far back as 1870, Upper Lake was the terminus of both the Cloverdale and Clearlake stage lines, which brought tourists to the mineral waters of Witter Springs, Saratoga Springs, and the Blue Lake resorts. Before Highway 20 went through in the late 1920's, the Bartlett Springs-Colusa Road connected Lake County to the Sacramento Valley. Highway 20 was originally called the Tahoe-Ukiah Route. Because of the terrain, old photos of stage coaches in Lake County usually show six-horse teams rather than the four-horse teams of neighboring areas.
