Banff and Jasper National Parks
From a jumping-off point in Calgary, Canada, head west into Banff National Park before hooking north from Lake Louise along the Icefields Parkway toward Jasper. Along the 140-mile (225.3-kilometer) parkway, you'll pass views of the Crowfoot Glacier and the Columbia Icefield, along with powerful Athabasca Falls, which is known more for its thunderous whitewater than for its height. Throughout the route, look up into the high summits of the Canadian Rockies, whose predominantly limestone cliffs tend to weather in a way that creates bands of snow that cling to many of the peaks year-round.
Gas and services are available only at the Saskatchewan River Crossing, and then only in the months from April to October.
