Yeah, but you have to find a parking space up there, which is impossible. Brave it and you will be rewarded, as Manton suggests.
As for Napa Valley, if you make it as far north as Calistoga go to the Vincent Arroyo winery and buy whatever he named after the dog. That's always the best stuff. Vincent Arroyo is out on the Silverado Trail.
I also liked the Sterling Winery, which is also in Calistoga (I think). It's a big industrial wine operation but it has (1) a self guided tour, so you are not bogged down with a slow-moving group and (2) great views of the valley. I think there's a cable car that runs up to the winery. Just embrace your inner rube tourist and enjoy!
