The source of the Jeker is near the village of Geer, in the Belgian province of Liège.

Places through which the Jeker passes include Waremme, Tongeren, Kanne, (all three in Belgium) and Maastricht.

Beginning in Kanne, it is possible to raft into the city of Maastricht on this relaxing river.

The trip from Kanne to Maastricht takes about two hours and crosses the border between Belgium and the Netherlands.
