The first half of this trail is uphill and fairly boring, notable only for it taking you across the continental divide and into British Columbia. Things get better as one makes a sharp left turn at Wall Creek. From here, surprisingly, most of the trail falls gently downhill. You walk through dark mature forest till suddenly you are in an alpine meadow and then, minutes later, a great wall of snow appears at the far end of Wall Lake.
It was drizzling slightly the day we hiked and low clouds cloaked the upper reaches of the nearly vertical rock walls which surround the lake. These conditions only added to the magical atmosphere of the place.
