The Erft (pronounced [ʔɛɐ̯ft]) is a river in North Rhine-Westphalia, Germany. It flows through the foothills of the Eifel, and joins the Lower Rhine (left tributary). Its origin is near Nettersheim, and its mouth in Neuss-Grimlinghausen south of the Josef Cardinal Frings Bridge. The river is 106.6 kilometres (66.2 mi) long, which is significantly shorter than it was originally. Due to the open-pit mining of lignite in the Hambacher Loch, the flow of the river had to be changed. The Erft gave its name to the town of Erftstadt, through which it flows, as well as to the Rhein-Erft district. It also flows through the towns of Bad Münstereifel, Euskirchen, Bergheim, Bedburg and Grevenbroich.

The Eifel Aqueduct was one of the longest aqueducts of the Roman Empire. The aqueduct, constructed in AD 80, carried water some 95 kilometres (59 mi) from the hilly Eifel region of what is now Germany to the ancient city of Colonia Claudia Ara Agrippinensium (present-day Cologne). If the auxiliary spurs to additional springs are included, the length was 130 kilometres (81 mi). The construction was almost entirely below ground, and the flow of the water was produced entirely by gravity. A few bridges, including one up to 1,400 metres (0.87 mi) in length, were needed to pass over valleys. Unlike some of the other famous Roman aqueducts, the Eifel aqueduct was specifically designed to minimize the above-ground portion to protect it from damage and freezing.

Blankenheim Castle (German: Burg Blankenheim) is a schloss above the village of Blankenheim in the Eifel mountains of Germany. It was built as a hill castle around 1115 by Gerhard I and became the family seat of the House of Blankenheim. The lords of Blankenheim were elevated to the countship in 1380. The counts were related to the counts of Manderscheid and, from 1469, were named Manderscheid-Blankenheim. With the extinction of the lines of Manderscheid-Gerolstein and Manderscheid-Kail (1742) the County of Manderscheid became the largest independent territorial lordship in the Eifel.

The Ahr Cycleway (German: Ahr-Radweg) is a cycle path, that runs from the source of the River Ahr in Blankenheim, in the Eifel region of Germany, along the river to its mouth on the Rhine near Kripp. Several sections are on an old railway trackbed. The route starts in the middle of the Eifel mountains and runs initially through a valley landscape with broad river bends. From the hamlet of Schuld the Ahr Valley narrows and swings around the settlement in a loop. In Altenahr, hillsides and rocks come close to the river itself and offer the best conditions for the wine growing. Behind the spa town of Bad Neuenahr-Ahrweiler the Ahr reaches its broad delta on the Rhine. The cycleway is not difficult and suitable for leisure cyclists. The route is uniformly signed with the cycleway's logo.
