Gonzaga is epic and there are some cool places along the way. Last I was there, May, the paved road went 7 miles past Puertocitos so that leaves like 60 miles of dirt. It's a darn good road but will give you some teeth rattle after a bit but there are some cool bays to check out on the way.
I'm not the full Gonzaga expert but I know it is hot there now but if it cools down you can hike up the old trail that the Jesuits used to access the Mission up near Santa Ynez (Catavinia). Lots of talk about making this friendly on dirt bikes but doubt it anytime soon.
