The Icefields Parkway is considered one of Canada's most scenic roads! Highlights along the route include Peyto Lake, Bow Lake, Athabasca Glacier, and Sunwapta Falls. . The highway goes all the way to Jasper from Lake Louise and is about 232km along. You can of course turn around whenever you do not need to drive the whole thing. There are some campgrounds and lodges along the Icefields Parkway and about 80km away from Lake Louise there is a gas station, a convenience store and a restaurant as Saskatchewan Crossing.
There is only ONE gas station at The Crossing Gas Station and Store at Highway # 93 and Highway # 11. But it has limited opening hours. It’s open only in the summer from mid-April to mid-October (call ahead to make sure it’s open), which means there are no gas stations between Lake Louise and Jasper in the wintertime. Make sure to check road reports if you go in winter!
All of my recommended stops are on the map! There is no cell service on this road!
