The Rhine River starts in the Swiss Alps and ends in the North Sea in the Netherlands.

Source of the Rhine

  • The commonly cited source is Lake Toma (Tomasee) in the canton of Graubünden in southeastern Switzerland.
  • From Lake Toma, the stream Rein da Tuma becomes the Anterior Rhine, which later joins the Posterior Rhine near Reichenau to form the main Rhine.

Where the Rhine Ends

  • After flowing north through Switzerland, along the French–German border, across western Germany, and into the Netherlands, the Rhine finally empties into the North Sea.
  • In the Netherlands, the river splits into several distributaries (such as the Nederrijn and Lek) before reaching the sea near the Rotterdam area.
