The Chephren Lake hike in Banff National Park is a short (8.2km, 258m elevation gain) but rewarding adventure along the Icefields Parkway. Starting from Waterfowl Lakes campground, the trail is mostly flat and winds through a forest before reaching the stunning blue glacier lake surrounded by majestic mountains. The trail can be muddy so I recommend bringing different waterproof boots if we're going to do pictures at the lake.
