I'm planning a trip for November and can't decide on the location. I'm debating between Petaluma and Santa Rosa. Petaluma is closer to the southern wineries in Sonoma, but Santa Rosa is closer to the northern wineries by Healdsburg. Is 101 the primary driving route or can you also use the Sonoma Hwy 12? Is it worthwhile to visit both northern and southern wineries? Does either location have better restaurants or nearby attractions? Any feedback or suggestions are appreciated!
