Southwest Holland’s annual Bloemencorso, aka flower parade, takes place on 20 April. Starting at 9.30am, it meanders through the towns of Noordwijk, Voorhout, Sassenheim, Lisse, Hillegom, Bennebroeck and Heemstede to the city of Haarlem, arriving there around 9.30pm. In past years fabulous creations have included cars, carriages, windmills and clogs shaped with tulips and hyacinths.
