The Canadian Rockies boast great national parks. Many Americans wrongly assume these parks are too far north of the border for practical exploration, and many Canadians never venture west to see Banff, Glacier, Jasper, Kootenay or Yoho. But the parks can be reached in one day’s drive from eastern Washington, or within a two-hour drive from Calgary International Airport. Take a look at the features of each park and plan a budget trip.
