De La in Santa Cruz, GGP in San Francisco, Black Mouse in Felton, and Stafford in Novato will fit that bill. If you're going 101 you just take 152 over to Watsonville. I would say it's about 45 min out of your way, but then you can also take Hwy 1 from Santa Cruz to S.F. Takes a bit longer, but that way you don't have to drive back over the hill to 101.
GGP and Stafford are both very close to your line of travel. Oh one other place to check out is the KOA in Willits. Very hilly and wooded, but bring some Technu for that couse. Tons of poison oak, same with Stafford, but not too bad.
