One of the world's most famous and most photographed lakes, a glacial lake of vivid turquoise in the Canadian Rockies at about 1,750 metres, ringed by towering peaks, with the Victoria Glacier looking down from its far end. Its remarkable colour comes from fine rock particles ground by the ice and carried in by meltwater, which reflect sunlight as a blue-green. On its eastern shore stands the historic Chateau Lake Louise hotel, from which an easy path follows the shore. In summer visitors paddle red canoes on the water, and hikers climb a mountain trail to little Lake Agnes and the old wooden teahouse above it. In winter the lake freezes into one of the most beautiful skating rinks in the world. Entry requires a Parks Canada daily pass of about C$12.25 per adult; parking is scarce, paid and full by dawn in summer, so the Parks Canada shuttles from mid-May to mid-October are the better choice. The lake usually stays frozen until early June.
