All children are invited to roll out their blankets at Park Valkenberg for King's Day on the Free Market. It’s the perfect spot to sell your old toys or those clothes you've outgrown. This way, you can make someone else happy while keeping some extra pocket money for yourself! 

Note: the free market in Valkenberg is really intended for children. Supervision is of course welcome, but commercial sellers are not allowed. 

Food and drinks can only be sold at the terraces and food trucks. 

The market officially starts at 11.00, but in practice, it’s often quite a bit earlier. To reserve a nice spot, it’s wise to arrive early in the morning.
