Emerald Lake is located in Yoho National Park, British Columbia, Canada.It is the largest of Yoho’s 61 lakes and ponds, as well as one of the park’s premier tourist attractions. Emerald Lake Lodge, a high-end lodge perched on the edge of the lake, provides local accommodation. A 5.2 km (3.2 mi) hiking trail circuits the lake, the first half of which is accessible to wheelchairs and strollers. During the summer months, canoe rentals are available; in the winter, the lake is a popular cross country skiing destination.
The lake is enclosed by mountains of the President Range, as well as Mount Burgess and Wapta Mountain.This basin traps storms, causing frequent rain in summer and heavy snowfalls in winter. This influx of moisture works with the lake’s low elevation to produce a unique selection of flora.
The lake had an impression on even the most seasoned of explorers: “For a few moments I sat [on] my horse and enjoyed the rare, peaceful beauty of the scene.” It was Wilson who gave the lake its name because of its remarkable colour, caused by fine particles of glacial sediment.
Due to its high altitude, the lake is frozen from November until June. The vivid turquoise color of the water, caused by powdered limestone, is most spectacular in July as the snow melts from the surrounding mountains.
