It may measure less than 50 square miles and have a population that doesn’t even crack a million, but San Francisco justly ranks as one of the greatest cities in the world. Famous for grand-dame Victorians, cable cars, a dynamic waterfront, and a soaring golden bridge, this city truly has it all. With trend-defining cuisine ranging from Michelin-starred dining to outrageous food trucks; world-renowned symphony, ballet, theater, and opera; plus almost boundless outdoor adventures, San Francisco justifiably stands out as one of the ultimate must-visit cities on any traveler’s wish list. The hardest part may be deciding where to go first. (Well, that and packing for the city’s famously unpredictable weather.) The Golden Gate Bridge is one of the city’s most iconic landmarks; you can walk or bike across the span to the Marin Headlands.
