Comprised mostly of numerous subdivisions, Cupertino did not have a traditional downtown until recently when Main St. Cupertino was added. Cupertino is known to be pedestrian and biker friendly with bike lanes designated on even its busiest streets. It is home to De Anza College, a hub of activity in the city, which includes a planetarium, museum, performing arts center and flea market. Shopping and dining of all kinds are available in this city filled with professional and urban vitality.
