San Francisco sets the bar high when it comes to parks. Nearly every neighborhood has one, although the grandest of all is Golden Gate Park, which stretches from the Height to the Pacific Ocean. With more than 1,000 acres of plush greenery, it's also home to The Koret Children's Quarter (a merry-go-round and playground), the de Young Museum, Conservatory of Flowers and Stow Lake. There's plenty of room to spread out for a picnic, go on a hunt for waterfalls, or polish a few soccer moves in an open meadow.
