Rudower Fließ

Along the narrow watercourse you wander here over wide meadows and fields.

The Rudower Fließ is a 9.2 kilometer long sand-shaped lowland stream in the Rudow district of the Neukölln district. It is also known as Rudow's tear gland due to its formation as an Ice Age meltwater channel.The channel was formed around 12,000 years ago during the last Glaciation of the Vistula.Source: de.wikipedia.org/wiki/Rudower_Flie

The "Neukölln's tear gland" comes as a long stream from Brandenburg and cuts the Wall Trail here. In Berlin, the brook suddenly becomes a small oasis. Thick forest, boggy ponds, water plants. You can stroll left and right of it, it stays rustic and doesn't get boring. And there is also a playground.
Neukölln can really score with many green sights. You can combine it with the view of the village and with the bird forest. It is also part of the Neukölln Garden Culture Trail. But be careful, there is a risk of fresh air poisoning.
