Fortress Lake is located in Hamber Provincial Park in British Columbia, and is accessible only by fly-in, and hiking or skiing over a 24 km (15 miles) route from Sunwapta Falls in Jasper National Park. Hamber Provincial Park has 24,000 hectares.
Trophy brook trout catch and release fly fishing in a remote and private wilderness area. Photos of the sizes of the fish caught in this lake can be seen here.
From British Columbia Parks:
“At high elevation, and with pristine wilderness, this park has excellent angling opportunities, and is prime grizzly and black bear country. A rustic campground is located at the east end of Fortress Lake and several traditional campsites are identifiable along the north shore of the lake. Each campsite has a pit toilet and bear pole for storing food. Because Hamber Provincial Park is an undeveloped wilderness area with no facilities, visitors should be self-sufficient and properly equipped.”
As an added bonus the following are photos of braver and tougher hikers than I who walked to Fortress Lake.

These hikers sent the tallest of their group first into the icy water to see how deep it was. However, the reward of reaching Fortress Lake would be waiting.
