This Gem Trek publication is a map and guide in one. It features a 1:50 000 scale topographic map with 25-m (82-ft) contour interval and UTM grid for use with GPS. This map covers all six of the most popular trail networks in the Lake Louise and Yoho National Park areas: Chateau Lake Louise, Moraine Lake, Skoki Valley, Emerald Lake, Yoho Valley and Lake O'Hara. Well-known trails on this map include the classic 'tea house hikes' to Lake Agnes and Plain of the Six Glaciers, Fairview Mountain, Larch Valley, Twin Falls and the Iceline. On the back of the map are 1:25 000-scale inset maps of Chateau Lake Louise and Lake O'Hara areas, photos and trail descriptions of 18 recommended day hikes, ranging from easy lakeshore walks to more demanding trails into alpine country. Four multi-day trips are featured. Information on two backcountry lodges: Skoki Lodge and Twin Falls Chalet.
