A spectacular remnant from the ice age, the Columbia Icefield is the largest icefield in the Canadian Rockies.
More than 30 glaciers make up the icefield, including one of the largest and most visited, the Athabasca Glacier.
A highlight of a visit is the Icefield Centre, which provides all the info you need to know about the formation of the icefield and its glaciers.
Guided hikes lead to the toe of the Athabasca Glacier from the Icefield Centre, or you can ride a snow coach across the icefield.
The Columbia Icefield is in Jasper National Park, reached by the Icefields Parkway linking Lake Louise and Jasper. The best way to travel here is by organized tour.
