The Flower parade of the ‘Bollenstreek’ is a colorful procession between Noordwijk and Haarlem that is held every spring on the first Saturday after April 12th. Traditionally the parade, equipped with lighting, starts on Friday evening in Noordwijkerhout. The 24-hour timeline on the bulb indicates at what time of day the cars pass the villages on the route. From every village you can see a famous building. The color green symbolizes spring, the Narcis, Hyacint and Tulip are the flowers that provide the parade with color.
