Comprising about half of the region’s Wine Country, Sonoma County hosts to a limited number of public transportation options, including several city-focused transit agencies (Santa Rosa CityBus, Petaluma Transit, Healdsburg In-City Transit, and Cloverdale Transit) and three regional transit agencies (Sonoma County Transit, Golden Gate Transit, and Napa VINE). Mendocino County, on the other hand, has an extremely limited public transit network due to its limited urban area confined to Ukiah, with service provided by Mendocino Transit Authority (MTA) that provides service as far south as Santa Rosa.

With limited services, these buses are used as the agency’s transit fleet that connect communities in the county, as well as two routes serving Sonoma County as far south as Santa Rosa, called the CC Rider (Route 65) to Fort Bragg via Ukiah and the South Coast Rider (Route 95) to Point Arena via Bodega Bay.
