Open Monday mornings and Saturdays all day, there's always something to find at this market. Lots of vintage items, the most gorgeous florals, and fresh food for making an amazing dinner that night.
The city's biggest flea market is hosted the first weekend of each month in and around a gigantic warehouse in the industrial area of NDSM in Amsterdam Noord. I love to snuff around the hundreds of stalls to find unusual props. Taking the boat to cross the IJ and leaving the old centre behind is very refreshing. Make sure to also have a drink in Noorderlicht while the sun sets.
