Sunwapta Falls is a popular stop along the Icefields Parkway, the road between Banff and Jasper National Parks. Here, the Sunwapta River funnels through some narrow gorges on its way to join the Athabasca River. The Upper Sunwapta Falls is a roadside stop, very easily accessible and thus frequently visited. The Lower Falls, however, is less crowded because you must hike to get there. The trail is not too difficult or lengthy, however, so you can still complete as a quick jaunt, then be on your way to another destination in the national park.
