Such a beautiful trail. I did this hike in August of 2017 right before the Kenow fire burned it's way through Waterton Park. this trail offers such unique views of Waterton National Park, Glacier National Park and Akamina Provincial Park. Would definitely suggest ascending on the Forum Lake side of the trail and descending on the Wall Lake side. An absolutely stunning hike. This is a difficult trail, but it's not so hard to discourage a reasonably in shape person. Most of the hike is on top the ridge at high elevation. 10/10 would recommend.
