5 days - lucky you!
Off the top of my head for pet friendly wineries-
Some other wineries will allow dogs outside and others don't allow them on the property at all. If you do a 'pet friendly wineries' google search quite a few should pop up. However, we're always discovering pet friendly places that aren't mentioned in generic books. Or we'll go to a place that is listed and it closed a year ago.
Most tasting rooms at The Wine Ghetto urban trail in Lompoc allowed pooches inside. We just ask wherever we go- some say yes, some say no.
As you know, that area is rural, so for architectural interests- it will be the wineries, Santa Barbara or Solvang. :)
Have you been to the Botanical Gardens in SB? Pups are allowed there.
Have you been to Jalama Beach? The road to get there is quite scenic and the beach is extremely isolated with miles of undeveloped land except for the campground. I've heard the weather can be extreme though, but we lucked out. We had a delicious breakfast at the little general store there,(Jalama Beach Cafe) but their known for their burgers. The ingredients were so fresh. Who would think in a spot like that they'd have tasty food?!
As for photography- that would be everywhere! The Central Coast is such a beautiful place, isn't it?
I'm sure you'll discover many places! Have a wonderful trip RRCazador!
