Keukenhof who does not know this amazing park only one hour drive from the capital of Netherlands. It is located between Amsterdam and The Hague, in a small city named Lisse. You do not need to worry how to reach there because it is pretty easy. If you somewhere close to Amsterdam Central Station, take a 15 mins train in direction to Schipol Airport, there you could use a Keukenhof Express Bus which is taking you directly to the park. I found it is the best way to get there so far. You could by combi ticket which include return transportation from Schipol Airport to Keukenhof as well as the entrance ticket to the park.  One thing you should remember before make your plan to visit this beautiful park, they only open during Spring, for only about a month. Go check their website in advance http://www.keukenhof.nl/en/.
