The Mumm Basin trail briefly enters Jasper National Park and overlooks Adolphus Lake. It's a much darker green lake than the glacial silt of Berg Lake a few kilometers away. While the Berg Lake Trail is busy, the stretch of trail by Adolphus Lake is quiet. Adolphus Lake is the end of the Canadian Rocky Mountains' most isolated trails - North Boundry and Moose River. Seven Days of you and Moose and Bears!
