Peyto Lake is a must visit while driving through the Icefields Parkway between Banff and Jasper. The bright water makes it a tourist hotspot. Glacial rock flour flows into the lake during summer months, giving it it’s signature turquoise color. I do prefer the winter color where there’s a richer pigment of blue, along with ice chunks. If you go at the right time, you can see the lake in its frozen state, along with some rich color!
