AFA locations, I second John's recommendations for the north coast, in particular the Three Capes scenic "detour" off 101, and would add the Oswald West walk-in park.
For the central coast (where I am), Yaquina Head, Cape Perpetua area, Heceta Head, Darlingtonia, and if you're lucky the wild rhodies will be blooming already n/s of Florence (Sutton, Honeyman).
Not too familar with the south coast but there's plenty there also. The north coast is the most scenic - just too wet for me to live there
