1.6 miles, Half day
San Francisco's famous shopping, culture and cuisine begin with a trip to Union Square. There is so much more to see just off the main plaza, however. This trip may start with high levels of retail punctuated by loud (yet endearing) cable car bells, but it then takes the visitor south of Market Street to the SoMa district, where world-class and lesser-known museums, an amazing park, great food and drinks and plenty of family-friendly (and unexpected) sites await.
Wear comfortable shoes and dress in layers, because San Francisco weather is not only unpredictable and unseasonable, but it changes from neighborhood to neighborhood.
This is a flat journey, so no need to worry about the city's famous hills.
