A few hours south of San Francisco is one of my favorite places on earth.

Stay at the Post Ranch Inn or the Ventana Inn. If you can't swing the steap prices. Camp out for $25 dollars at Ventana and book message at the spa the best of both worlds!
Take hikes in the Pfiffer redwood forrest, picnic on the side of highway 1, eat dinner at Nepenthe. Stop at the Big Sur Bakery for breakfast. You won't want to leave...
