The Swist is a stream, 43.6 kilometres long, in the German Rhineland. It rises on the northern edge of the Eifel at 330 metres above sea level and empties rom the right and southeast into the Rhine tributary, the Erft, between Weilerswist and Bliesheim.Occasionally the Swist is also called the Swistbach, and locals often just call it der Bach ("the stream").
The Swist flows through the municipality Swisttal, the town of Meckenheim and Flerzheim, a village in the borough of Rheinbach. There are cycle paths by the side of the stream along this stretch. The Swist gave its name to the municipality of Swisttal and the town of Weilerswist. Its source area is situated at the northern edge of the Eifel. The Swist used to be considered the longest stream in Europe until it was canalised and straightened.
Its source lies at 330 m above sea level (NN) in the northern part of the Eifel in the Ahr Hills, north of the village of Kalenborn in the collective municipality of Altenahr in the county of Ahrweiler. The Swist has an average gradient of 5 ‰ and flows initially to Vettelhoven (Grafschaft) in a northeasterly direction and then descends at a gradient of just 1.3 ‰ through the Fore-Eifel. It continues along the western slopes of the Ville in the börde landscape of the Rheinbach Loess Plateau through Meckenheim, Flerzheim, Morenhoven, Heimerzheim and Metternich. The municipality of Swisttal and the village of Weilerswist derive their names from the stream. At 106 m above NN the Swist empties into the Erft between Weilerswist and Bliesheim.
