It surrounds the Richelieu River as the river flows north from Lake Champlain in the United States to the Saint Lawrence River northeast of Montreal at Sorel-Tracy, Quebec. Dramatically different from the mountainous terrain to the south, the river valley is a vast plain that has been developed with extensive farmlands.

In the 21st century, the Richelieu River is very popular for both U.S. and Canadian recreational boaters, providing a connection that can bring boaters all the way from the outlet of the Saint Lawrence River to New York Harbor. A number of old fortifications exist dating back to the 17th century; they were built by the French in an effort to try to prevent the Iroquois from using the river as a way to attack the French settlers in the area. Fort Richelieu is at the mouth of the Richelieu River. Fort St. Louis (now Fort Chambly) at Chambly, Fort Sainte-Thérèse, and Fort Saint-Jean at Saint-Jean-sur-Richelieu, are on the way. Fort St. Anne Isle La Motte, Vermont in Lake Champlain is near the river's source. The region is informally known as la Vallée-des-Forts.
