On April 27, 2026, NDSM will turn orange again during the 14th edition of NDSM Vrijhaven. The city's largest children's free market is not just about selling, the NDSM wharf is also a place full of play and fun. Of course, children display their treasures: toys, books and unexpected finds. But you can also come up with an idiosyncratic activity and rent a market stall to bring it to life, such as: throwing cans, a mini performance or another playful idea that fits in a stall or just outside. For visitors, as usual, this means strolling through stalls, rugs and activities, where there is always something to do.
