Stick to the coast both north and south. Slightly longer but way way more beauty. Stops... San Simeon to see elephant seals breeding November through January. Astoria for Bow Pickers fish and chips and Goonies stuff. Tillamook for ice cream. Oregon or Washington state parks for yurt or cabin camping. Forks area for pacific beaches. Hope for stormy weather. Port Angeles area for Olympic national park. Once near ONP you'll find plenty of places to sleep in your vehicle. Repeat southbound for the drive of a lifetime.
