A beautiful hike with wonderful views of Banff, the Bow River, and surrounding mountain throughout the hike. You can begin the hike at the lower trailhead or 400 metres higher at the upper trailhead. If you walk to the trailheads from downtown Banff, account for the extra (uphill) distance. Please note: several reviewers have described this trail as easy or even "the easiest hike" in Banff. The trail is officially rated moderate difficulty due increase in elevation on the switchbacks. Not really a problem if you're in good shape. Those who aren't used to walking uphill or aren't used to breathing thinner air at higher elevations (the Banff townsite is over 1400 metres above sea level) should count on taking breaks on the way up.
