The most beautiful Lake Minnewanka is actually a glacial lake located in the eastern area of Banff National Park in Canada, at least 3.1 miles northeast of the Banff town site. The lake is 28 kilometers long and 466 ft deep, making it the longest lake in the mountain parks of the Canadian Rockies. There’s a power dam at the west end. The lake is fed by the Cascade River, flowing east of Cascade Mountain, and runs south through Stewart Canyon as it empties into the western end of the lake. Numerous streams flowing down from Mount Inglismaldie, Mount Girouard and Mount Peechee on the south side of the lake also feed the lake. Aboriginal people long inhabited areas around Lake Minnewanka, as early as 10,000 years ago, according to stone tools and a Clovis point spearhead discovered by archaeologists. The area is rich in animal life i.e bears, elk, mule deer, mountain sheep, and the easy availability of rock in the mountainous terrain was most important for fashioning weapons for hunting. The western end point of the lake can be reached by following Lake Minnewanka road from the Trans-Canada Highway. Boat tours are easily accessible near the parking lot. A hiking and mountain biking trail runs along the northern shore of the lake, passing Stewart Canyon and six backcountry campsites. Dams were built in 1912 and 1941 to supply the town with hydro-electric power. Lake Minnewanka itself has a popular with recreational SCUBA divers. Lake Minnewanka is actually the largest lake in the park, and really a great place of picnic point.
