Lergravsparken is one of Copenhagen's many staffed playgrounds (and it happens to be one we go to a lot). It has all of the classic playground equipment (swings, slides, sandboxes, and a large rope climbing structure for older kids). When the playground is staffed, they have bikes that kids can borrow, an indoor playhouse filled with toys and activities, and the staff often hold special events. If you find yourself in this area of Copenhagen with kids, this is a great place to let them play!
