Keukenhof is located in South Holland in the small town of Lisse, south of Haarlem and southwest of Amsterdam. It is accessible by bus from the train stations of Haarlem, Leiden and Schiphol. It is located in an area called the Dune and Bulb Region (Duin-en Bollenstreek).
Well, not of the flowers anyway. Keukenhof is the world's largest flower garden, over 70 acres (around 32 hectares) of parkland filled with more than 7 million bulbs - tulips, daffodils, hyacinths, narcissi, gladioli. But mainly it's the tulips - of course, since this is the Netherlands.
