Banff is one of the most renowned tourist destinations in Canada and the most popular in the Canadian Rockies. It is the oldest national park in Canada, the second in North America (following Yellowstone in Wyoming) and the third oldest park in the world (following Royal in Australia). It encompasses 6,641 square kilometres (2,564 square miles) including the Lake Louise area and part of the Icefields Parkway.
Waterton Lakes National Park is a place "where the mountains meet the prairie," a unique juxtaposition of prairie flatlands and some of the most ancient mountains in the Canadian Rockies. Protecting 203 square miles in the southwest corner of Alberta, the park is bordered by British Columbia on the west, Montana to the south and to the north and east by forest and private lands.
