Santa Rosa is the largest city in Sonoma County, California. Depending on traffic conditions, Santa Rosa is 1-2 hours north of the Golden Gate Bridge in San Francisco on Highway 101. Driving through Marin County and southern Sonoma can be mind-numbingly slow during the afternoon commute and on weekends. You can also fly Horizon Air to Charles M. Schulz Airport from Seattle, Portland, Los Angeles, or Las Vegas. Being largely suburban, a personal vehicle remains the most common method of getting around Santa Rosa and the surrounding area. There is, however, the Santa Rosa CityBus, but frequency, operating hours, and coverage leave much to be desired. Sonoma County Transit and Golden Gate Transit also provide service in Santa Rosa, but focus mainly on inter-city travel. Bicycling in Santa Rosa is a reasonable option. Most destinations are reachable via not-too-busy roads, and notable car-free pathways exist from downtown to and beyond the western city limit. The primary off-street bicycle and pedestrian path system is the Prince Memorial Greenway, extending along the banks of Santa Rosa Creek from City Hall in the heart of downtown, out beyond the city to the west. On the western edge of downtown, near the Marriott Hotel in Railroad Square, this connects to the Joe Rodota Trail, a paved off-street path going to Sebastapol paralleling CA highway 12. Much of the city is relatively flat. The downtown core is easily walkable, and if one were staying downtown they could conceivably while away a day on foot.
