The cycle route tracks the river Aller from its confluence with the Weser to its source. An alternative route diverts to Magdeburg. There is so much to see along the way, not least the equestrian town of Verden, which rose to fame through its world-class tournaments and horse shows. The former ducal town of Celle boasts more than 500 timber-framed buildings in its old quarter under historical protection. Many rare species of bird can be seen in the Ilkerbruch conservation area. Alternatively, you can learn all about the history of the automobile at VW's Autostadt exhibition complex in Wolfsburg or visit the Phæno science centre to discover for yourself how natural phenomena work. Terrain: mainly flat, occasional gentle hills in certain stages. The route is mostly on asphalt and traffic-free in the main, and links the Weser Cycle Route with the Elbe Cycle Route. Scenery: idyllic countryside along the river Aller and its catchment area: Aller-Leine valley, Südheide (southern heath), Drömling nature reserve. Beyond Lower Saxony: Flechtingen hills, Elbauen Park in Magdeburg, headwaters of the river Aller.
