Most direct route would probably be Hwy 101, would be boring.
PCH (Hwy 1) is very scenic but slower as it has curves aplenty and dips and swoops all the way. I recommend it.
You could visit Hearst Castle and check out the beaches with the elephant seals. Cambria is a very nice town. Carmel is picturesque and expensive.
From about Cambria take Hwy 46 to Paso. You will go through the west Paso winery area. Lotsa good wines grown there.
