Helen Lake Trail is an 11.7 km (7.3 mi) out-and-back from the Helen Lake parking area on the Icefields Parkway, with the lake as the turnaround. Allow four to five hours. A sustained climb through rooted forest eventually opens into alpine meadow, with Bow Lake, Crowfoot Glacier and several peaks appearing well before the lake. If you want a full mountain walk with changing views, the route earns its length. If the lake itself is your main reason to go, temper expectations: Helen Lake is modest, and the scenery along the way is the bigger reward.
