One of the first hiking trails you come to when entering Banff National Park (coming from Calgary) is Johnston Canyon. The entire trail is about 6 miles and passes several waterfalls on the way.
The picture below is the Lower Falls, the first of the waterfalls you get to and it is an easy walk. As the hike continues, the trail gets a bit more rugged.
As you can see, the Lower Falls plunges into this giant pothole, a cauldron of swirling water with amazing colors. There is bridge and cave you can walk through to get closer to the falls, providing you don’t mind getting wet! Not something I’d try with a camera, regardless of the weather sealing.
