Treat Banff to Jasper via the Icefields Parkway as a full scenic travel day — about 232 km on Highway 93 North with limited services, a summer-only fuel stop at Saskatchewan River Crossing, and stops sequenced from Lake Louise toward Jasper.
Plan Banff as a walkable national-park town base, with clear guidance on transit, park access, Lake Louise and Moraine Lake systems, and how many days to spend.
Plan Canmore as a mountain-town base just outside Banff National Park, with free local transit, Banff day trips on Route 3, and clear guidance on Kananaskis versus national-park pass systems.
Visit Lake Louise lakeshore and Moraine Lake without private parking by using Roam, Parks Canada connector rules, licensed operators, and the right seasonal reservation system.
