Second the advice to head to Paso Robles to Hearst Castle. We go from Morro Bay to northern Arizona. The route home is 40 to 15 in Barstow, 58 north to Bakersfield where we take 99 north to 46 west to Paso Robles. That section of 48 ends at 101 in Paso. A left turn onto south bound 101 a couple miles to 46 west to 1 just a couple miles south of Cambria and San Simeon.
Heading south on 1 will get you to 101 in San Luis Obispo where 1 and 101 merge. Just south of Ventura you can access the next section of 1 to Santa Monica to Newport Beach. That section from Ventura to the north end of Malibu you’re right on the beach.
