Although America's Yellowstone was the world's first national park, Canada was the first country to create an agency specifically devoted to national park creation, management and preservation. Parks Canada celebrates its 100th birthday this year, and in a century of park stewardship it has safeguarded some of the world's most famous landscapes and icons, including the Prince of Wales Hotel in Alberta's Waterton Lakes National Park. Parks Canada's scope includes 10 World Heritage Sites and four UNESCO Biosphere Reserves, ranging from remote marvels to easily accessible human playgrounds. Fourteen of our favourites follow.
