The St. Lawrence River is one of Canada's most emblematic natural monuments. The 1,197 km-long river flows through Quebec's three largest cities: Quebec City, Trois-Rivières and Montreal. Since the beginning of Quebec's history, the St. Lawrence River has played a key role in the development of the cities and the country. A major trade artery for Canada, it has developed in parallel with the Canadian economy.
The St. Lawrence River has been an integral part of the history of the settlers, of Quebec and, of course, of Canada. This immense river crosses Quebec from Quebec City to Montreal, via Trois-Rivières. This majestic waterway is full of surprises. In Tadoussac, whale pods come to spend the summer, while in Montreal, cruise ships take tourists for dinners and brunches with panoramic views.
In Quebec City, you'll discover Île d'Orléans, one of the first territories conquered by European settlers. Stroll among century-old churches and unspoilt forests. Finally, in Trois-Rivières, Parc Saint-Quentin is a small park nestling in the heart of one of the archipelagos of the St. Lawrence River. Here you can take a stroll, go to the beach or enjoy a family picnic.

The St. Lawrence River begins its course above Quebec City, in the Gulf of St. Lawrence, where the French archipelago of Saint-Pierre-et-Miquelon is located. As it flows south, it crosses the Quebec border and plunges into Lake Ontario, in Canada's Great Lakes region. The St Lawrence estuary is the largest in the world, measuring 48 kilometres wide and 370 kilometres long.

It was Jacques Cartier, the famous French explorer who discovered much of Quebec, who named the St. Lawrence River. He decided to give it this name because he arrived there on the feast day of Lorenzo of Rome. However, long before the Europeans arrived in Canada, the First Peoples had already named the river "the river that walks".
Later, the river was used as an artery for inland exploration of North America. The St. Lawrence is the direct connection between Quebec's two largest cities. As a result, it is an important commercial artery for the Quebec economy.

In the north, near Quebec City, a small island 34 kilometres long floats in the St. Lawrence River. Accessible by boat or bridge from Quebec City, Île d'Orléans was one of the first territories conquered by European settlers. Here, time seems to have stood still. The stone houses of the era still stand proudly, and the native forest seems untouched by man's damage to nature. All around the island, you can go hiking, stop off at the island's pubs and restaurants, and even stay overnight in this atypical island setting.

Trois-Rivières lies between Montreal and Quebec City. The city, which is slightly less touristy than its neighbours, is nonetheless a little Quebec gem, with museums, an interesting historical heritage and architecture that reminds us that Trois-Rivières was the second city to be colonised by Europeans.
As well as being an exciting city, Trois-Rivières boasts an impressive nature park on the St. Lawrence River. Set in a small archipelago, the island of Saint-Quentin is home to a nature park teeming with beaches, century-old trees and hiking trails. It's a place where Quebecers come to kayak, enjoy a picnic or admire the scenery. Admission costs $5.50.
