The Icefields Parkway , also known as Highway 93 north, is a scenic road in Alberta, Canada. It parallels the Continental Divide, traversing the rugged landscape of the Canadian Rockies, travelling through Banff National Park and Jasper National Park. It links Lake Louise with Jasper to the north. At its southern end, the Icefields Parkway terminates at the Trans-Canada Highway (Highway 1). Highway 1 west goes to Yoho National Park in British Columbia and Highway 1 east to Lake Louise and the Town of Banff. A second parkway, the Bow Valley Parkway also links Lake Louise and the Town of Banff. Known as Highway 1A, this road parallels Highway 1 and, at the midpoint, passes the Castle Mountain junction where Highway 93 south, or the Banff-Windermere Highway, branches southwest into Kootenay National Park in British Columbia.
