Even larger, more diverse and delightful than the markets in Amsterdam and Leiden is De Bazaar, located in Beverwijk. The website says it's "a place where cultures meet," and I can't think of a better description! There's a free market (Oosterse Markt - Oriental Market) and a paid section (2 euros for all-day entrance to the Zwarte Markt (Black Market), Grand Bazaar, Computer Market & ChinaTown) and I honestly think there isn't anything you can't buy at this place.

Many people travel to De Bazaar by car, but it is also possible to take public transportation. Just disembark at the NS Station Beverwijk and walk for ten minutes - and you're there! It's open every Saturday and Sunday from 8:30am-6:30pm.
