How many times have you taken the kids on a trip and found yourself stuck downtown, surrounded by nothing but adult-centered activities? Yuerba Buena Gardens is the San Francisco city cure for that dilemma. Not only does Yuerba Buena offer large expanses of grass for kids to run to their heart's delight, it also has a carousel, a bowling alley and an indoor ice skating rink. And if those classic kid activities don't work, try "Zeum," an interactive museum with a mission of fostering creativity in young people to ignite the imagination and inspire lifelong learning. Still not enough activities? Then bring the gang over to the nearby Metreon for a well-deserved movie and meal.
