A glacial lake in the Valley of the Ten Peaks at 1,884 m, famed for its vivid turquoise colour. Walter Wilcox reached it in 1899; Lillian Gest documented its history in History of Moraine Lake (1970). The lake sits in the shadows of ten distinct peaks (including Mount Fay, Mount Little, and Mount Bowlen). The world-famous turquoise comes from glacial flour: fine silt from the Fay Glacier meltwater stays suspended in the water; sunlight reflects blue and green wavelengths, creating a saturation that looks almost artificial. The iconic Rockpile view has appeared on Canadian currency and countless postcards.

Access

Moraine Lake Road is managed as a shuttle, transit, commercial-operator, and bicycle access corridor rather than a normal personal-vehicle road. Parks Canada shuttle, Roam Transit, private operators, Lake Connector eligibility, early departures, and parking rules change by season; confirm current access with official sources before planning around a specific departure. See Summer logistics for the practical checklist.

The thaw

Moraine Lake is high-altitude and usually frozen until late May or early June. For bright blue water, late June through September is the usual window. Late September is busiest (larch season). For photography, sunrise and late-day light are usually more forgiving than midday.

Trails

Rockpile Trail 0.8 km return, 30 m (stone stairs to the “Twenty Dollar View”); Lakeshore 2.9 km return (flat; boardwalks over glacial streams at the far end are the quietest spot); Consolation Lakes 6 km return; Larch Valley 3.5 km one-way, 535 m (branches off lakeshore; continues to Sentinel Pass for Minnesota Wall and Paradise Valley views); Eiffel Lake 11.2 km return; Wenkchemna Pass 19.4 km return (Continental Divide). Seasonal group-size restrictions may apply during grizzly activity periods; carry bear spray and verify current Parks Canada notices before starting.

Fauna and gear

Prime grizzly bear habitat; buffaloberries attract bears in late summer. American Pika and Hoary Marmot on the Rockpile (listen for the pika “eeep”). Lake breeze is cold even in July; pack a windbreaker. Sturdy sneakers fine for lakeshore; mid-height waterproof boots if extending to Larch Valley. Canoe rentals and lake-use rules can change by operator and season. Water activity rules can also change with aquatic invasive species and disease controls; verify current Parks Canada guidance before paddling, wading, or putting personal gear in the water.

Photography

Rockpile: wide-angle 16–24 mm to capture lake and Ten Peaks; use lower tiers for foreground interest. Lakeshore: walk approx. 500 m down for better mirror reflections (more sheltered from wind). A circular polarizer (CPL) cuts surface glare and reveals the depth of the turquoise.
