From The Fairmont Chateau Lake Louise, it’s a 3.5 km (2.2 mi) walk to a lovely hanging valley high above Lake Louise. The trail climbs steadily through a subalpine forest to tiny Mirror Lake. Then it’s a short, relatively steep climb beside a waterfall to Lake Agnes. Some continue higher where Beehive Mountain lookouts provide breathtaking views of Lake Louise far below, but most simply linger over lunch at Lake Agnes Teahouse. — Andrew Hempstead
