Destination guide
Calgary: The gateway to Banff and the Canadian Rockies
Most people fly to Calgary to get to the mountains, and that is a good reason: Banff is 90 minutes west and Lake Louise about two hours. The city itself has a strong food scene, the Stampede every July, and North America's largest urban pathway network.
Best time to visit: June to September for hiking and the warmest mountain weather, with the Stampede in the first half of July. December to March for skiing at Banff Sunshine, Lake Louise and Norquay. May and October are the value months — fewer people, and the scenery does not care.
