Located in Canada’s famous Banff National Park, Emerald Lake is the largest lake located in Yoho National Park in the province of British Columbia. It’s just 20 minutes drive west from it’s famous neighbor Lake Louise, but is not as well known. With a beautiful green hue it truly stands up to it’s name. The color is most intense in early summer when there is a high amount of glacial silt flowing from the surrounding mountains. Due to the high elevation of the lake it remains frozen from November to early June.
