Cerulean Lake

Cerulean Lake is an alpine body of water situated at 2,250 meters (7,380 feet) elevation in Mount Assiniboine Provincial Park, featuring distinctly blue waters that mirror the surrounding mountain peaks. The water's striking coloration comes from glacial minerals suspended in it, which reflect light in a way that creates that characteristic deep blue tone.

Mount Assiniboine Provincial Park was established in 1922 to protect these alpine lakes and surrounding landscapes as part of British Columbia's conservation efforts. This protected status has preserved the mountain environment and its natural features for over a century.

The lake sits within lands long inhabited and traveled by the Ktunaxa, Shuswap, and Assiniboine peoples, who continue to hold significance in this region. Local Indigenous communities maintain deep connections to these mountain waters and the surrounding wilderness.

The lake is only accessible on foot via hiking trails from Sunshine Village or Mount Shark, as no roads reach this remote alpine area. Visitors should prepare for challenging mountain terrain and unpredictable weather conditions typical of high elevation.

The lake is part of a three-lake system with Sunburst and Magog Lakes, each offering a different vantage point of Mount Assiniboine's pyramidal peak. This arrangement allows visitors to experience the mountain from several distinct angles on a single trip.
