The first stop outside Québec City's urban sprawl is one of the region's most interesting. Grosse Île served as a major quarantine station for European immigrants in the 19th and early 20th centuries. A tour of the Grosse Île National Historic Site sheds light on this little-known aspect of North American history. It is also possible to visit the 21-island Île aux Grues archipelago. For all trips, wear warm clothing and comfortable shoes.
