Ptarmigan Lake is an alpine lake at the foot of Ptarmigan Peak. The main access to the lake is a hiking and skiing trail which begins near the Lake Louise Mountain Resort. The lake drains eastward into Baker Lake and then into Baker Creek, which flows into the Bow River. The Skoki Ski Lodge is located beyond the lake and over Deception Pass.
