Paris and the Île-de-France reach
Paris downstream to Vernon and Les Andelys — France
The upstream end of the cruised Seine. Vessels moor in central Paris and work downstream through a green, meandering valley of chalk cliffs, small towns and country houses. The river loops heavily here, so progress over the ground is slow relative to the distance travelled on the water.
Navigation: Locked and canalised throughout, with a series of large navigation locks maintained by the French waterway authority. Bridge clearances in Paris are low, which is one reason Seine vessels are among the smallest in European river cruising.
