I remember that sunny morning of April 2008 when I visited Keukenhof with my colleagues from Pakistan. Keukenhof is the world's largest flower garden where approximately 7,000,000 (seven million) flower bulbs are planted annually.
It's located in South Holland in the small town of Lisse, south of Haarlem and southwest of Amsterdam. Bus can be catched from train stations of Haarlem, Leiden and Schiphol to access this bulbous paradise.
Kaukenhof was established by mayor of Lisse in 1949, to promote the Netherlands flower export industry ( Netherlands is the world's largest flower exporter now).
It opens normally from the last week of March to mid-May. In 2008 when I visited, it was opened from 20 March to 18 May. While in 2010, it will be open from 18 March to 16 May according to its official website.
This historic park is spread colorfully over a big land piece of 32 hectare with 15 kilometers of footpaths. It's very well planned and enormously filled with blooming tulips, hyacinths, irises, daffodils and other spring bulbs.
The area where it's situated is also know as the "Dune and bulb Region" (Dune- en Bollenstreek in Dutch). The flowers fields outside the garden are evidence of this.
This park is also quite visible through following video.
Overall, this was a great experience and I enjoyed it very much. I get excited by the magnificent specs of color whenever I remember this exquisite work of art and nature. I strongly recommend that take your camera along on this unique experience to get it with you for your whole life.
