For strong, experienced hikers, Caldron Lake is a premier dayhiking destination in the Canadian Rockies. Start very early, so you’ll have time to roam beyond the lake: generally north, through the low pass between Mistaya Mtn (left / west) and Caldron Peak (right / east). You’ll see Delta Glacier (left / northwest), and a smaller glacier on Mt. Peterson’s south flank (ahead / north). But the reward here isn’t a specific view; it’s the joy of wandering in such a high, remote, lonely place, and the raw beauty you’ll witness in every direction. In this photo, Kath is returning from the edge of Delta Creek canyon. That’s Mt. Peterson behind her. To her left (your right) is a shoulder of Caldron Peak.
