• Only on market weekends, roughly twice a month, so check the calendar on the IJ-Hallen site before you set out
• Free F4 ferry from the back of Amsterdam Centraal to NDSM-werf, then a 5-minute walk to the hall
• Uneven floors in the hall and across the wharf, so watch your step with toddlers and expect a bumpy stroller ride

IJ-Hallen is a flea market in a former shipyard hall at the NDSM wharf, with up to 600 stands on a market weekend. Anyone can rent a stand, so the mix changes every time, from secondhand clothes to home furnishings and odd finds.

Kids with a little pocket money can hunt for bargains among the stalls. The floor of the hall and the wharf is uneven, so strollers bump along.
