Arriving in San Francisco

Flowers in your hair are not mandatory, but no one’s going to give you a hard time for your headgear in most of this laidback city’s eclectic neighborhoods. The free spirit of San Francisco may be a cliché by now, but something of that famously open-minded, easy-does-it character has survived the city’s changing fortunes and the tech invasion.

Hit up all the highlights on your first visit: The Golden Gate Bridge, Alcatraz, The Mission, The Castro. If you have time, pay a trip to one of the excellent art museums, like the San Francisco Museum of Modern Art. Next time, linger and explore. This is a city that’s lovely to explore on foot or by bike, but if you want to cover a lot of ground, the public transit is great and it’s hard to beat the historic open-air Trolley system.
