Follow the cutoff to Moraine Lake, a luminescent turquoise gem nestled beneath a long row of crumbling summits that form the Valley of the Ten Peaks.
Back in town, stop by the Lake Louise Visitor Centre (+1 403 522 3833) for a geology summary of the Canadian Rockies. Out back, you’ll find the start of the Bow River Trail, a 4.4-mile [7.2-kilometer] interpretive loop. For a grandstand vista of the glacier-capped peaks, glide up the flanks of Mount Whitehorn on the Lake Louise Sightseeing Lift & Gondola (+1 403 522 3555. June-late Sept.; Fare).
Most people find it hard to tear away from Lake Louise, but a great swath of sensational country awaits north along the Icefields Parkway (Hwy. 93), Canada’s highest road. Named for the hundred-plus glaciers visible along the route, the parkway bowls along for 143 miles [230.1 kilometers], passing through long, forested river valleys cradled by nearly continuous walls of dazzling peaks. Drivers frequently spot elk, moose, bighorn sheep, mountain goats, and black bears. A lucky few see a grizzly, wolf, or caribou. After about 20 miles [32.2 kilometers] of forest and crag, pull over beside Bow Lake for a good look at Crowfoot Glacier clinging to the scabrous cliffs of Crowfoot Mountain. From the lake’s north end, you can make out Bow Glacier Falls, a ferocious cascade plummeting nearly 500 feet [152.4 meters]. A 3-mile [4.8-kilometer] trail leads to its base.
At Bow Summit, follow the spur road west and stroll to where Peyto Lake Viewpoint overlooks a creamy blue lake, its glacial source, and the broad, forested valley of the Mistaya River. Continue past Upper and Lower Waterfowl Lakes, and walk down to Mistaya Canyon, a sinuous fissure so narrow and deep you may have trouble seeing the water that crashes through it.
At Saskatchewan River Crossing, pick up the gravelly bed of the North Saskatchewan River and begin a climb toward the treeless alpine zone. Not far beyond the Weeping Wall (the damp brow of curving limestone to your right), the road makes a sharp curve and begins a steep ascent. As you round its northern flank, consider hiking to the crest of Parker Ridge, a fairly strenuous climb to a panoramic vista of the Saskatchewan Glacier, curving down from the edge of the vast Columbia Icefield.
Soon you cross Sunwapta Pass into Jasper National Park (Visitor Center +1 780 852 6176. Adm. fee), descending to the toe of Athabasca Glacier, a broad ramp of ice and snow slanting down between Mount Athabasca (left) and Snow Dome. Signs along the spur road record the pace of its retreat during the past hundred years. Hike to the edge of the glacier, but don’t venture onto the ice without a qualified guide—the crevasses are deep, and people have died in them recently.
Across the highway, learn about glacial mechanics at the Icefield Centre, a thronged activity complex where you can grab a bite, book a Snocoach tour of the glacier, or visit the best natural history museum in either park. A large three-dimensional projection of the Columbia Icefield clearly shows its extent (125 square miles [323.8 square kilometers]) and its three meltwater drainages (Arctic, Atlantic, Pacific). Other displays examine wildlife of the alpine zone and explain how glaciers form, grow, and retreat.
Follow the Sunwapta River northwest as it rushes down into the forest and gathers strength from countless creeks and waterfalls spilling from the Winston Churchill Range to the west. Peer over the cliffs at Sunwapta Falls, a great ripping blast of foam, then coast along the Athabasca River to the Mounts Fryatt, Brussels, and Christie Viewpoint. Perched on a natural mineral lick, this is one of the park’s most dependable sites for spotting mountain goats. Next, turn onto Hwy. 93A and take in Athabasca Falls, always crowded, and for good reason. Here, the river’s milky blue waters funnel into a chasm and break into a creamy plume of whitewater with Mount Kerkeslin as a backdrop. Several miles farther north, take the slow, 9-mile [14.5-kilometer]) side trip to the base of Mount Edith Cavell, a vast wall of dark gray rock and snow that sweeps upward nearly a vertical mile from the parking area. Angel Glacier spills from the cliffs like an immense petrified waterfall, and two short loop trails beckon.
