In winter, ski mountaineers descend on the Wapta Icefield, a series of glaciated ridges and peaks that spans a large portion of the Continental Divide in Banff National Park. But summer is prime time here: In July, temperatures hover in the mid-seventies and it's light until 11 p.m.Take advantage by trading skis for crampons on a hut-to-hut glacier traverse along moraines, lakes, and the high-alpine cirques of the Northern Rockies. Yamnuska Mountain Adventures' three-day trip ($785 per person, July–September; canadianrockieshiking.com) makes for a great introduction to technical ice travel, with just enough creature comforts. Nights are spent in the Bow and Peyto huts, mountaineer shelters with fully equipped kitchens (just bring a sleeping bag—your guides will do the cooking) and views of the 10,000-foot peaks fanning out in all directions.
