We visited Icefield Parkway in winter on the way driving back to Vancouver. I decided to give Johnston Canyon a visit, while dad wanted for a nap. I would say the scenery in the canyons in Canadian Rockies is way better in winter than in summer. The ice scenery is just incredible. The downside was, I was hiking wearing backetball shoes, so I fell several times due to the icy trail.
Along with Maligne Canyon and Mistaya Canyon, Johnston Canyon is one of the three most famous canyons in the Rockies. It draws lots of tourists in all time of the year, with no exception on the day I was there. I only continued to the Lower Falls, but there is Upper Falls and Ink Pot further up the canyon that worth a visit too.
