Lake Lois, a famous attraction in Banff National Park in the Rocky Mountains of Canada, is a birthday gift from the British Governor-General of Canada to his daughter, so named after his daughter, you can see the fascinating scenery of the lake. Lake Lois is set against the snow-covered ice peak, and what is unfolding in front of you is a clear green lake water, like a huge emerald, a small boat in the lake swings the ocean, and the water is calm as a mirror.
