I must confess that I am very partial to a bargain (who isn't, right?). It goes without say, therefore, that I absolutely love markets, to the horror of my partner, who absolutely hates them. Amsterdam has no shortage of markets, ranging from the most popular market the Albert Cuypmarkt, organic food markets on Noordermarkt and Nieuwmarkt on Saturdays, to the best known flea-market on Waterlooplein, weekly on Monday-Saturday. These markets are all great, but rather small and pedestrian when compared to the mammoth IJ-Hallen (http://www.ijhallen.nl/en/index.php).
The monthly IJ-Hallen in Amsterdam North tops my market list. According to the IJ-Hallen website, "The IJ-Hallen is the biggest and most unique flea market in Europe." Whether this is true or not, I'm not sure, but it certainly is big and the stuff on sale is extremely diverse and interesting. The location, in an industrial area in Amsterdam North, which can be reached by free ferry from Amsterdam Central Station, adds to the journey and experience.
