Peyto Lake
📍 Bow Summit, Icefields Parkway, Banff National Park, Alberta, Canada
A glacier-fed lake of startling turquoise in a forested valley below Bow Summit, the highest point on the Icefields Parkway — one of the most photographed views in the Canadian Rockies.
What makes it marvelous
Peyto Lake lies at 1,860 metres in a valley of the Waputik Range, between Caldron Peak, Peyto Peak and Mount Jimmy Simpson. It is fed by Peyto Creek, which drains Caldron Lake and the Peyto Glacier, part of the Wapta Icefield. Each summer the glacier pours fine rock flour into the lake, and the suspended particles turn the water a vivid turquoise. The lake is the source of the Mistaya River and is named after Bill Peyto, an early Banff park warden and mountain guide.
Why visit
A short walk from the Icefields Parkway brings you to a viewpoint high above one of the bluest lakes in the Rockies.

Most of the Rockies’ famous lakes are seen from their shores. Peyto Lake is seen from above. A short walk from Bow Summit, the highest point on the Icefields Parkway, brings you to a viewpoint over a valley where a long, curving lake of almost luminous turquoise lies in a dark forest.
The colour is glacial. Peyto Creek drains the Peyto Glacier, part of the Wapta Icefield, and every summer it carries fine rock flour into the lake. The suspended particles scatter sunlight and turn the water a bright, milky blue that is strongest from midsummer, once the lake has thawed and the meltwater is running hard.
The lake sits at 1,860 metres between Caldron Peak, Peyto Peak and Mount Jimmy Simpson, and is the source of the Mistaya River. It takes its name from Bill Peyto, an English-born guide who became one of Banff’s early park wardens. Parks Canada rebuilt the viewpoint, trails and parking in 2021 — a sign of how many people stop here. Come early or late in the day to have it closer to yourself.
