• Road quality: Excellent on 101; narrow and winding on coastal routes like Highway 1

For a smoother drive, avoid peak hours in San Francisco (8-10 AM, 4-7 PM). The scenic alternative, Highway 1, adds 2-3 hours but offers breathtaking coastal views.

Weather along the route varies; microclimates can shift from foggy coastal mornings to sunny inland afternoons. Check forecasts for each segment.
