Lange Bretten is known as the last city wilderness of Amsterdam. De Lange Bretten is half a kilometre wide and ten kilometres long – making it three times larger than the Vondelpark. Many different types of animals live in Lange Bretten. Buzzards and falcons hunt in the area, and the water is home to thousands of frogs, toads and fish. The "muddy boot trail” (wear your wellies!) is a highlight, and the nature track meanders through an area full of character.
