The closest city to the Canadian Rockies  is Calgary , Alberta , 128 kilometers (80 miles) east of Banff . Vancouver , British Columbia’s largest city, is a major gateway to the mountains for international travelers. It lies on Canada’s West Coast, 830 kilometers (515 miles) west of Banff. Edmonton , 360 kilometers (224 miles) east of Jasper , also has an international airport. Even though Vancouver is a lot farther from the Canadian Rockies than Calgary, it is a popular starting point, as the trip across British Columbia by rail, bus, or car is spectacular.
