[[Image:Rur zwischen Monschau und Dedenborn 30-01-2005.jpg|right|thumb|The Rur between Monschau and Dedenborn during winter]]
The Rur rises in the [[HautesHigh FagnesFens]]/Hohes Venn National Park, near the {{convert|696|m|ft|adj=on}} tallhigh [[Signal de Botrange]] in Belgium at an elevation of {{convert|660|m|ft}} above sea level. South of [[Monschau]] it flows into Germany, through [[North Rhine-Westphalia]]. It flows first through the northern part of the [[Eifel]] hillsmountains.
After {{convert|39|km|mi}} it reaches the [[Rur Dam|Rurstausee]], the second-largest artificial lake in Germany. After approximately {{convert|160|km|mi}} it flows into the Netherlands, and at its {{convert|170|km|mi|adj=on}} mark it flows into the river [[Meuse]] at the city of [[Roermond]].
Major tributaries of the Rur include the [[Inde]] and the [[Wurm]]. CitiesThe towns along the Rur are Monschau, [[Heimbach]], [[Nideggen]], [[Düren]], [[Jülich]], [[Linnich]], [[Hückelhoven]], [[Heinsberg]] (all in Germany) and Roermond (Netherlands).
In the 1960s and 1970s, the northern part of the Rur was heavily polluted by the [[tailings]] of many German coal mines. Neither fish nor other organisms could be found, and it was dangerous to swim in the river. Foam flakes regularly flooded parts of the city of Roermond. After the closure of the mines, the waste water treatment in Germany and the Netherlands greatly improved. Only the lower part of the river is still contaminated.<ref>[ Water quality chart of the Rur published by the Ministry for Climate Protection, Environment, Agriculture, Nature Conservation and Consumer Protection of the German State of North Rhine-Westphalia]</ref> The water in the upper part of the river is so clean that trout and more than 30 species of fish are back. After an absence of 125 years, [[salmon]] returned to the Rur in 2004.
