Unprecedented opportunities for people-watching compete with the picturesque views of the Golden Gate Bridge and the lush Marin headlands as you stroll or jog down Marina Green. This district is a microcosm of San Francisco: old Victorians and Edwardians, new apartment buildings, tourist attractions like Fisherman's Wharf and Alcatraz, and arguably the city's best nightlife and shopping boutiques. Cow Hollow, now the area bordered by Chestnut and Union streets, was a dairy farm in the 1800s but is now home to watering holes of another sort. These neighborhoods are ground zero for newly stock-optioned 20- and 30-somethings who can't get enough of the renovated Mediterranean-style flats and condos and the convenient location. Commuting to the Financial District or Multimedia Gulch is painless and freeway access is easy, too. Cultural attractions abound in this district: Fort Mason, the Exploratium, and the Palace of Fine Arts are within walking distance of many residences.
