The Columbia Icefield can be found within Jasper National Park and is North Amercias largest non-polar body of ice. Covering 325 square kilometres with solid ice up to 1150 feet deep, it is an absolute must-see on any visit to the Canadian Rockies and this is one of the most fun and comfortable ways to explore this awe-inspiring natural wonder. This tour must be booked well in advance at a specific time, and lasts around 1 hour 30 minutes.
