In Quebec City, La Citadelle of Quebec provides visitors a glimpse into the military past of the area. La Citadelle remains an active military facility, so all tours are guided, and visitors will learn about the fortress and its history; guests may also explore the Governor General's residence, which overlooks the Saint Lawrence River and has served as the second home to every Governor General of Canada since 1872. During the summer months, the morning Changing of the Guard can be viewed, as well as the evening Retreat.
This one might not be visible from space, but the Great Wall of Saskatchewan near Smiley is quite a feat in its own right. The Wall was started by Albert Johnson in 1962 and continued to grow over the years as rocks from neighboring farms were added to the project. Completed in 1991, it was built without any cement or mortar.
Moose Jaw, where dozens of murals adorn the fronts and sides of buildings in the downtown corridor, is also home to two fascinating, multimedia tunnel tours. The town used to have an extensive underground system used for various purposes—both mundane and nefarious—and visitors can now participate in the "Passage to Fortune" tour, which gives guests an idea of the life of a Chinese immigrant in the late 19th century, and "The Chicago Connection," which looks as Moose Jaw's role in supplying liquor to the United States during Prohibition.
Don't miss the views from the Top of the World Highway, which runs from Dawson City to Alaska—a narrow, meandering road that takes drivers on a spectacular journey through unspoiled Canada.
And while most travelers buy souvenirs, for those more inclined to leave something behind, there is the Sign Post Forest in Watson Lake. The forest began simply enough, by Carl Lindley, an American Army man working on the Alaska highway; Lindley missed his home in Danville, IL, so he posted a sign in 1942, pointing in the direction of Danville and listing the mileage to make it there. In the decades since, more than 10,000 signs have been posted—pointing toward the hometowns of so many visitors.
