Each year in spring more than seven million tulips, daffodils, and hyacinths bring an incredible amount of colours and fragrances to the 32 hectares of Keukenhof, the famous flower park in the province of South-Holland. The gardens are part of the 15th-century estate of Slot Teylingen and used to be the castle's kitchen garden. In 2026 the park opens its doors from the 19th of March until the 10th of May.
