I would contact the CHP (California Highway Patrol) a few days ahead to make sure the coastal road Highway 1 is open. Occasional landslides happen, and there are only a few detours possible. With that out of the way, I would recommend bringing the couple widest lenses you have, and a 70-200 or thereabouts.
These are all on APS-C, so you have to do the math for comparison.
