You can find more information on their own website http://www.keukenhof.nl. Each year they have a central theme, and the opening is performed by the Queen or someone from the royal house.
Tips & tricks:
- The best time to visit is end of April. We did try end of the season like May but we did not find flowers anymore, most of them being cut down.
- come early in the morning because it is a huge space and you will need like 6-8 hours to scratch the surface of it.
- dress comfortable and wear walking shoes.
- you do have restaurants inside, but i find it best to bring your own sandwiches and water.
- buy a map in the beginning to guide you through this area.
- if you buy tickets form airport, these includes also the bus trip to there.
To quote from their own site about the history:
Where Keukenhof is situated now, was a hunting area in the 15th century. Herbs for the kitchen of the castle of Jacoba van Beieren were also collected here; hence the name Keukenhof.
The current park was a section of the sizeable estate of Slot Teylingen, with beautiful untamed bushes and dunes. After the decease of Jacoba van Beieren Keukenhof fell into the hands of rich merchant families. Baron and baroness Van Pallandt invited landscape architects J.D. and L.P. Zocher, designers of the Amsterdam Vondelpark, to make a design for the garden around the castle. This design, in the English landscape style, has always been the basis of Keukenhof.
At the moment the estate belongs to a Corporation. On the initiative of the Lisse mayor of that time and a number of leading flower bulb growers and exporters, an open air flower exhibition was organized here for the first time in 1949. This expanded to an annually recurring event that has always drawn great numbers of visitors from all over the world. This is how Keukenhof became the park that we now know.
