Personally, I like the Russian River Valley this time of year. I know you've done the wine tasting thing; but for me, RRV is more about the scenery.



I'd drive up Route 1 to Guerneville (it takes longer this way, but the views are worth it). Along the way you'll see ocean, redwoods, a different climate every ten minutes. Then grab lunch in Guerneville and take it with you down along the river. It's quiet, rustic nature at her best.



Then head south, maybe stopping in Healdburg for some gentrified window shopping and maybe a drink. Last, have dinner at the new El Dorado Kitchen in Sonoma.
