Recommended stop near Banff
The road that runs parallel to Johnston Canyon is a highly recommended stop in the outskirts of Banff. Starting from Johnston Canyon Lodge, there are two sections: the lower falls, that you can reach in less than half an hour, and the upper falls, which add an extra hour (round-trip) to the walk but are certainly worth it for the height of the falls. The trail is clearly marked and has spectacular wooden walkways that at some points can be dozens of feet above the river.
