One of my favorite Spring day trips that we have taken while living in Dusseldorf is just a few hours into The Netherlands to Keukenhof Gardens! Open this year from March 21st-May 20th, this 32 hectare garden is the "most photographed place in the world!" It doesn't just have tulips either...there are over 7 million tulips, daffodils and hyacinths all in bloom at the same time! Take a peak at the flowers in bloom and make sure you stop and smell the tulips at the Keukenhof Gardens if you get the chance!
Oh and you must try the ham and mustard sandwich, it is to die for!!
