About one-third of Berlin consists of green spaces and bodies of water. The map shows everything that takes place outdoors: playgrounds, parks, swimming spots, forests, animal enclosures, and outdoor festivals. The most practical filter is distance—with small children, the commute determines how the day goes, not the activities themselves. For playgrounds, the map also notes whether there’s shade, whether the area is fenced in, and whether there’s water nearby for splashing. If the weather turns: Under {In Case of Rain}, you’ll find all the covered options.
