Begin on CA-29 through the Carneros region, then merge onto I-80 East to I-580 West for the quickest path to US-101 South. From there, follow US-101 down the Central Coast. The route is well-paved, with most sections four-lane divided highway. Fuel and route economics: gas prices vary significantly, save about $0.50 per gallon by filling up in the Central Valley rather than near coastal tourist towns. Budget for $120 in fuel round-trip. Rest stops are plentiful: every 30 to 40 miles, you'll find a Caltrans rest area with clean bathrooms and vending machines.

• CA-29 to I-80 merge: watch for traffic around Vallejo
• US-101 near San Luis Obispo: construction zones possible
• Alternative CA-1 route: scenic but adds 2 hours
