Gem Trek maps are recommended by all major guidebook publishers that cover the Canadian Rockies including Lonely Planet, Frommers, Moon, and Dorling Kindersley. Here’s what Lonely Planet has to say about our maps:
For the Canadian parks, the best topographical maps are produced by Gem Trek Publishing (www.gemtrek.com). Maps range in scale from 1:35,000 to 1:100,000 and cover Banff and Mt Assiniboine, Jasper and Maligne Lake, Waterton Lakes, Lake Louise and Yoho, Bow Lake and Saskatchewan River Crossing, the Columbia Icefield, Canmore and Kananaskis Country. All major trails and points of interest are clearly marked on the maps, which are waterproof and tear-proof. They’re available everywhere, including from retail stores, bookstores, grocery stores and many gas stations.
