Best Athabasca Glacier and Columbia Ice Explorer Tours

The Athabasca Glacier in the Canadian Rockies covers an area of 2.3 square miles (6 sq km), and is between 300 and 980 feet (90–300 m) thick. According to Parks Canada, it is the most visited glacier in North America, due to its accessibility from Banff and Jasper National Parks. Take a bus to the glacier's edge, and then get on a special snow coach to reach the glacier itself. You’d better hurry – the glacier is receding at a rate of about 16 feet (5 m) per day!
