Columbia Icefield in the Canadian Rockies, Canada, is a vast icefield straddling the border of Alberta and British Columbia, located within Jasper and Banff National Parks. Visitors can take part in glacier tours, walk on sections of ice with guides, enjoy scenic viewpoints along the Icefields Parkway, and learn about glacial landscapes and formations. Covering roughly 325 square kilometres, it is the largest icefield in North America’s Rocky Mountains and feeds several major glaciers, while its meltwater contributes to river systems that flow to different oceans.
