California is a driving state. Distances are long, Los Angeles to San Francisco is around 6 hours on Interstate 5, and Highway 1 doubles that but is the reason to come.

Coastal fog burns off late morning in summer. San Francisco in July is often colder than San Diego in January.

Tipping is expected rather than optional. Budget 18 to 20 percent for table service, a couple of dollars a drink at a bar, and 15 to 20 percent for taxis.

Prices on shelves and menus exclude sales tax, which is added at the till and varies by state and city.

## Local knowledge

Contributed by guides, operators and creators on the ground. Community advice, kept separate from official sources.

Drive Highway 1 north to south

Going south puts you on the ocean side of the road, so every pull out is a right turn and you never cross traffic for a view.

## Frequently asked questions

Outside central San Francisco, yes. Los Angeles and San Diego are built around driving, and the coastal and national park routes have no useful public transport.

April to June and September to October give warm days, thinner crowds and clear coastal air. July and August are busiest and foggiest on the coast.

Ten to fourteen days covers San Francisco, Highway 1, Los Angeles and San Diego without rushing. Seven days means picking two of the three cities.

Yes by US standards. Budget 200 to 300 USD per person per day mid-range in the cities, less inland and in the desert.
