Glacier Skywalk —
Canada's stunning new Glacier Skywalk pops 35 meters out the side of a cliff in Alberta's Jasper National Park. The glass-floored observation walkway hangs 280 meters above Sunwapta Canyon.

Educational experiences —
A Discovery Trail cliff-edge walkway leading to the glass platform includes six interpretive stations and an audio tour focusing on the glaciology, biology and ecology of Canada's Columbia Icefield region.

Fair-weather attraction —
Owned by Brewster Travel Canada, the Skywalk took two years to build -- work could only be carried out seasonally due to Jasper National Park's cold winters. It reportedly cost CAD$21 million ($19 million) to construct and will be open May through October.

Skywalk criticism —
Skywalk opponents are concerned about the ecological impact of the project and the privatization of a national park site.
