Upper Florence Lake

Upper Florence Lake is a freshwater lake located on the west skirt of Ladies Peak and Cape Horn, and North of Grindstone Mountain, in Chelan County, Washington. The lake is a popular area for hiking, swimming, and fishing, especially for rainbow trout. Lower Florence Lake is located further down the slope of Mary Pass from Upper Florence Lake, approximately 15 miles west of the city of Leavenworth. Self-issued Alpine Lake Wilderness permit required for transit within the Lake Alice area.

Along with neighboring lakes, Lake Florence was given its name by Albert Hale Sylvester, a topographer for the United States Geological Survey working throughout the North Cascades National Park Complex around 1900.
