On Saturday April 21, 2018 the Flower Parade of the Bollenstreek will travel from Noordwijk to Haarlem. In the three days before the parade the floats will be ‘pierced’, that is to say, covered and decorated with bulb flowers. Many hundreds of volunteers will be busy for days with the piercing or pinning of thousands of hyacinths, tulips and daffodils to the floats. This unique event can be admired at the hall of DeLeeuw Flowerbulbs in Sassenheim. You will find more information on the opening times and entrance fees on the Admissions page.
