In the shadow of the spectacular bell tower of the Muntplein, now a gallery and souvenir shop, on the Singel canal lies this floating flower market open 6am to 5pm Monday to Saturdays. The disappointingly short row of stalls is laid out along the southern side of the Singel canal on a series of floating pontoons that are accessible from the street.
Here you can find a variety of cut flowers and plants, including the ubiquitous tulip as well as bulbs, seeds and all the necessary equipment to allow you to grow your own. Also available are a wide variety of tacky souvenirs including wooden tulips, clogs both wooden and porcelain and models of windmills highlighting this markets status as something of a tourist trap.
If you are interested in plants and flowers, you should be able to find enough of interest here to while away a half an hour and a fistful of Euros. Otherwise you'll probably make it from one end to the other in 5 mins and be on your way.
