Morane Lake in the Rocky Mountains

Moraine Lake’s Colour Comes From Physics and It’s More Impressive for Knowing That

The flat, impossible turquoise of Moraine Lake is produced by glacial rock flour – particles so fine they remain suspended in meltwater and reflect specific blue-green wavelengths of light. The process is measurable and reproducible. Knowing the mechanism does not make the colour less extraordinary when you see it in person; it makes it more so, because what you are looking at is glacial erosion rendered visible by optics. The surrounding ten peaks complete a setting that genuinely looks staged.

The lake sits in the Valley of the Ten Peaks, about 14 kilometres from Lake Louise village in Banff National Park. Getting there by private vehicle in peak season is now effectively not an option. Parks Canada runs a mandatory shuttle from Lake Louise, and private vehicles are turned away from the Moraine Lake road from mid-May through mid-October unless you have a lodge reservation. Shuttle tickets sell out online; book through Parks Canada before you arrive, not on the day.

The Rockpile

The viewpoint everyone wants is the Rockpile, a short scramble up a boulder pile at the far end of the lake from the lodge. The classic photograph – all ten peaks reflected in the turquoise water – comes from here. The scramble takes five minutes. By 9am there is a queue for the viewpoint; arrive at the first shuttle of the day.

Hiking

The Lakeshore Trail is flat, 3km return, and appropriate for everyone. Sentinel Pass is the serious option: 11.6km return with 725 metres of elevation gain, ending at one of the highest maintained trails in Banff. Views back down into the valley justify every step; allow four to six hours and start by 7am. Consolation Lakes at 5.8km return is the middle ground with fewer people than the main Moraine Lake trails.

Where to Stay

Moraine Lake Lodge operates late May through September and books out almost immediately when reservations open each January. Rooms run CAD 500 to 1,000 per night. The lodge has canoes available for guests. For non-lodge visitors, rental canoes from the dock cost approximately CAD 155 per hour. Lake Louise village has the Fairmont Chateau Lake Louise at the luxury end. Canmore, 45 minutes east, is the best base for budget travellers.

Park Pass

Banff National Park requires a pass: CAD 10.50 per person or CAD 21 for a day pass. The annual Discovery Pass at CAD 75.25 per adult pays off quickly for stays of more than a few days across the Canadian national parks.
