The Columbia Icefield Skywalk is a cool glass-floored walkway that juts out over Sunwapta Canyon, giving you killer views of Mount Athabasca and Mount Kitchener. You can only get there by shuttle bus from the Icefield Centre, but once you're on the skywalk, you'll feel like you're floating above the valley floor 280 metres below. It's a must-do for anyone looking for a thrilling perspective of the stunning Canadian Rockies! It is only open in the summer months!
