West Side Community Garden, Upper West Side
A neighborhood sanctuary nestled between two apartment buildings, the West Side Community Garden was founded in 1976 when it was transformed from a trash-filled lot to the lovely escape it is today. Privately owned but open to the public daily, it's famous for its thousands of blooming tulips which culminate in an annual festival each spring.
