Daytrip outside Amsterdam: Keukenhof, Amsterdam

Simply beautiful!! I dont know the statistics of how many acres and how many varieties of tulips etc. You can definitely spend half a day in this beautiful place.
If you have time, dont go with the tour agencies. You should be able to find your way to the garden, wherever you are.
It is very close to the airport, so if you have just arrived, you can leave your bags in the airport, and take the bus (there is a DIRECT bus from the airport). No point in going to Centraal station, and coming back in pretty much the same direction right? If you are going from Centraal, you need to change trains. There is no direct bus/train. Perhaps, you can go to airport and then take the direct bus?
It is open for 2 months during april-may timeframe.

A short train ride from Amsterdam in the town of Lisse is Keukenhof-the world's largest flower gardens.
Keukenhof sits on 32 acres of immaculately cared for land. The colors of the flowers are some of the boldest and brightest that you may ever see. Even if you are not a flower enthusiast, Kuekenhof still warrants a visit.

Not too far from Amsterdam and accessible by train, is the famous bulb area. Hundreds of colorful flowerfields can be found in this area during spring time. You can though this area by bike or car or you can go to the Keukenhof, a large park where all kinds of flowers are grown. Keep in mind that the Keukenhof is only opened in spring! (until mid May)

Keukenhof Gardens in Lisse
A beautiful spring garden just outside of Amsterdam. It's open from mid-March to mid-May usually. A must see really for anyone venturing to the Netherlands.
Just a short (1 hour?) bus ride from Amsterdam. It's a nice ride through Holland, and the bus driver gives all kinds of interesting information on the way.

Keukenhof Gardens in Lisse, Holland, It is a short drive from Amsterdam and well worth it during tulip season. Be careful, though, because there are hordes of people there that want to see it too! It is nearly impossible to take a picture without someone wandering through at just the right time.

A side trip to Keukenhof is a must. These amazing gardens are a delight for the senses. We spent a whole day here, walking, having lunch and stopping for endless photo ops.

The welcoming committe at Keukenhof are very friendly staff. I like the way that they get dressed up and hand out the pamflets to you and even show you where to go when you are a dum tourist.

keukenhof is a graden full of tulips... but dun go at the early of spring... try for mid of spring.. might get a better scene !!! that time i went there... was too early for the tulip. too bad!!~

I love this postcard! Will make sure the next trip to Amsterdam will be when Tulips bloom their prettiest and pay a visit to Keukenhof near Lisse.
