Columbia Icefield Skywalk, Glass-floored cantilevered viewpoint in Jasper National Park, Alberta, Canada

Columbia Icefield Skywalk is a glass-floored observation platform in Jasper National Park that extends high above Sunwapta Valley. The structure allows visitors to look down through transparent walkways and see the landscape and glacier-carved terrain beneath them.

The platform opened in 2014 as an initiative to increase visitor access to natural attractions in the Canadian Rocky Mountains. The project expanded tourism offerings in the region and drew more people to experience the glaciated landscape.

The name honours the Columbia Icefield, whose meltwater feeds the Sunwapta valley below. The steel is weathering (corten) steel, chosen so the structure rusts to a brown surface that matches the rock and records the passage of time. The walkway was designed to be cut into the slope rather than built on top of it, so it reads as a continuation of the mountainside.

Visitors can take a shuttle bus from the Glacier Discovery Centre to reach the platform, with regular service during operating hours. Warm clothing is recommended as the location is exposed to wind and cold temperatures year-round.

The glass surfaces can withstand extreme temperatures ranging from minus 40 to plus 40 degrees Celsius and support up to 400 people at the same time. This engineering achievement allows the platform to endure the harsh conditions of the mountain environment.
