Rocky Mountains, BC & Alberta
As advised by Wikipedia, the Canadian Rockies consist of the Canadian segment of the North American Rocky Mountains range. The Canadian Rocky Mountain Parks World Heritage Site is located in the Canadian Rockies. It consists of four national parks: Banff Jasper Kootenay Yoho and three British Columbia provincial parks.
With their total area being 180,000 km² you’d be hard pressed NOT to see the Rocky Mountains (white outs and fogs excluded of course) when traveling.
This mountain range was simply magnificent with the various peaks appearing to stand guard over their own areas!
Travel by train is highly recommended as you are able to experience so much more of the Canadian Rockies!
