Useful information:
With a total length of 2,900 kilometers, the St. Lawrence River is one of the longest rivers in the world and is also called the "great waterway" in the language of the North American natives.

The river was discovered by the Frenchman Jacques Cartier and runs from the Canadian province of Ontario to the US state of New York.

The river is navigable along its entire length and is of great importance as a transportation route. But the river is also very attractive for tourism.
