Which Canadian national park contains the turquoise Lake Louise?

The Canadian national park containing the turquoise waters of Lake Louise is Banff National Park.

Lake Louise lies in Alberta’s Canadian Rockies, inside Banff National Park. Its striking blue-green colour comes mainly from fine particles of glacial rock flour carried into the lake by meltwater from Victoria Glacier. When sunlight scatters through the suspended particles, the water takes on its famous turquoise appearance.

The lake was originally known by the Stoney Nakoda name Ho-run-num-nay, meaning “lake of the little fishes.” It was later named Lake Louise after Princess Louise Caroline Alberta, Queen Victoria’s daughter and the wife of Canada’s Governor General, the Marquess of Lorne. The nearby settlement and mountain also carry the name Louise.

Banff, established in 1885, is Canada’s oldest national park and forms part of the Canadian Rocky Mountain Parks UNESCO World Heritage Site. Visitors often confuse Lake Louise with Moraine Lake, another famous turquoise lake in the region. Moraine Lake is also in Banff National Park, but the quiz’s landmark is specifically Lake Louise.
