Little Sister is located northeast of Middle Sister and Big Sister in the Bow Valley section of Kananaskis Provincial Park. The Three Sisters are some of the most photographed mountains in the Canadian Rockies and appear on many calendars and postcards. The Three Sisters are an easily identifiable landmark to the travelers on the Trans-Canada Highway as they are immediately south of the town of Canmore, Alberta, which is the primary gateway into Banff National Park. Little Sister is the nearest of the three to the Trans-Canada Highway. Originally named The Three Nuns, they were later officially named The Three Sisters. Little Sister is the lowest of the three, but the most difficult to climb since it requires technical rock climbing rather than the scrambles up Middle and Big Sisters. The first ascent of Little Sister was made by Lawrence Grassi in 1925. (see also Mount Lawrence Grassi)
