The Seine river flows 776.6 kilometers from its source in the Cote-d'Or (at St-Germain-Source-Seine, north of Dijon) to the sea at Le Havre. It is navigable from the confluence with the Aube river at Marcilly. From Paris to Le Havre it is France's busiest waterway. Four other navigable rivers flow into the Seine: Yonne, Loing, Marne and Oise; these rivers connect into the inland waterway network of France - north, east, and south. The combined Seine Basin dominates the waterways of northern France. The Seine is unusual in its many boucles, smooth curving loops that cut across the straight-line path to the sea. The limestone cliffs shown above are at Le Petit Andely, Normandie.

Hello Tom, Thanks so much for all the work you have done over all these years and your freely offered support, it really is very much appreciated. So much so it has enabled a group of complete amateurs to take a 40 foot steel Dutch motor boat from Arnhem to very close to the Med, all via your guides, and we're still going!! Stay safe. John C.
