Moraine Lake is a glacially fed lake in Banff National Park, outside the hamlet of Lake Louise, Alberta, Canada. It is situated in the Valley of the Ten Peaks, at an elevation of approximately . The lake has a surface area of . The lake, being glacially fed, does not reach its crest until middle to late June. When it is full, it reflects a distinctive shade of azure blue. The unique colour is due to the refraction of light off the rock flour deposited in the lake on a continual basis by surrounding glaciers. The road to Moraine Lake is only open during the summer months (June-Sep). Since 2023, Parks Canada has closed it for personal vehicles year-round with only its shuttles, public transit and commercial operators allowed to access the road. Visitors can also bike the road. Tourism Hiking trails The area around the lake has several walking/hiking trails that are, from time to time, restricted. The trail most commonly taken by tourists is The Rockpile Trail, which is along the actual moraine. The trail is approximately long, with an elevation change of . The view of the lake from the top of the rockpile is one of the most photographed locations in all of Canada. That view of the mountains behind the lake in Valley of the Ten Peaks is known as the "Twenty Dollar View", as Moraine Lake was featured on the reverse side of the 1969 and 1979 issues of the Canadian twenty dollar bill; see . The area often experiences congestion due to the high level of tourism. Along the same trail-head, the Consolation Lakes trail starts, which is approximately 3 kilometers long, with an elevation change of . Upon reaching Consolation Lakes hikers may continue along to the upper lake, which is not visible from the end of the lower lake. There is, however, no clearly marked trail, and can often be a scramble over large rocky areas. Near the canoe docks of Moraine Lake Lodge there is another trail-head. This trail-head is the start of two trails, one of which branches out into four different trails - so there are in total, five trails starting at that trail-head (Moraine Lake Lake shore Trail, Eiffel Lake, Wenkchemna Pass, Larch Valley, and Sentinel Pass). The Lake Louise & Yoho Map provides information on these trails. Mountaineering routes The Neil Colgan Hut can be reached
