If you want to have a beautiful drive with very little traffic and few tourists this time of year, take Highway 128 from Calistoga and drive through Knights Valley to Alexander Valley. It is beautiful this time of year.
This is Hanna Winery and Vineyards on Highway 128.
This stand of trees in the Alexander Valley Vineyards was remarkable last year. The rain has thinned the leaves a bit this year, but the color is still lovely.
Old Oaks on the Fieldstone Vineyards property are covered with hanging moss. Acorns crunch underneath your shoes as you walk through the mossy short grass. I loved the bright yellow leaves of the grapevines in contrast with the trees.
