Lake Louise is the name of a small village, but the nearby lake is much more famous. It is located in Banff National Park. Both are named after Louise Carolina Alberta, a child of the English queen Victoria. The province of Alberta is also named after her.

The lake is famous because of the striking colour of the water. The glaciers scratch the limestone rocks thereby releasing minerals, which are fed to the lakes via the rivers. Because the supply of water to the lake varies, the colour of the water also varies. It may be bright blue, striking green, but also blackish.
