Lost Lake Trail
The run
Trail report
Starting near the historic Crowsnest Pass, this trail winds its way up through dense spruce forests into the subalpine.
The terrain consists of loose rock, a few cross-ditches, and a couple of steep, loose ascents where 4LO is highly recommended to maintain traction.
The destination is Lost Lake, a pristine body of water perfect for a quiet lunch, photography, or setting up camp for the night away from city lights.
