This lake is a must see when visiting Banff National Park. Absolutely one of my favorite places in the park. So beautiful. The color is mesmerizing. For the best views of the lake you have to hike further than the first lookout point that is easely reachable from the parking lot. After about twenty minutes of easy walking, you’ll be able to enjoy the best views on Peyto Lake, almost undisturbed.
