Speeltuin Binnenste Buiten is a large playground in Delfshaven, just off Heemradsplein.
It’s great for kids of all ages. It has 2 large sandpits, with cubby houses and a small slide. It has a small water play area for warm weather. It has a flying fox, a large ropes course/jungle gym and a big basketball court out the back.
There is a small fee to enter (currently 50c per child) but it’s worth it.
