The hiking trail over Wilcox Pass was used frequently before the Icefields Parkway opened in 1940. It is best in late June through to mid-August, although snow can remain in Wilcox Pass until late July. Wilcox Pass is in Jasper National Park, Alberta and accessed just off the Icefields Parkway (Highway 93).

These little guys seem to populate the wood piles near campgrounds wherever one travels in the mountains.
The Wilcox Campground road is at an elevation of 2040m with a steep climb through alpine forest.
At approximately the 1.7km mark the trail emerges above the treeline gaining 120m in less than a kilometre.
In another 2.5km there is a steep climb to flat alpine meadows and the viewpoint for the Athabasca Glacier.

Only a small portion of the Columbia Icefield is visible from the Icefield Parkway. The Athabasca Glacier is the most accessible and visible of the glaciers which flow from the Icefield, but there are numerous others. Over three hundred square kilometres in area, the depth of the icefield varies from 100 to 365 metres. The average annual snowfall on the upper reaches is seven metres.
From the viewpoint the trail moderates, opening out onto a ridge overlooking the Icefields Parkway and the Athabasca Glacier. The hiker can feast his/her eyes upon the massive ice-covered Mount Athabasca (3491m) (11454ft), Mount Andromeda (3450m) (11,319ft), the Snow Dome (3460m) (11,399ft) and Mount Kitchener (3511m) (11,500ft).
Mt Kitchener was named in 1916 after Horatio Herbert Kitchener (Viscount Kitchener), a British Field Marshall who organized the British armies at the beginning of WWI. He was lost when HMS Hampshire struck a mine in 1916.

Norman Collie and Hermann Woolley completed the first ascent of Mount Athabasca on August 18, 1898. Collie described a vast icefield that stretched westward and surrounded by unknown peaks.

The Snow Dome was named in 1898 by
J. Norman Collie . This dome-shaped mountain is covered by the Columbia Icefield. The water produced from this mountain flows into three oceans through the Saskatchewan and Nelson rivers to the Atlantic, though the Columbia to the Pacific, and through the Athabasca and Mackenzie Rivers to the Arctic.

Past the viewpoint the trail climbs along the edge of a creek, then levels out across alpine tundra and heads northwest into the long U-shaped pass between Wilcox and Nigel peaks.

At 4.0km is the summit of Wilcox Pass (2374m). Wilcox Pass and peak are named after
Walter Wilcox, whose party first crossed the pass in 1896 on horseback. The pass became the usual route north as it avoided the
Sunwapta Gorge and the Athabasca Glacier, which nearly blocked the valley below.

It is here and at the other end of the pass that the hiker will find
Bighorn Sheep.

To continue on to Tangle Falls the route continues north across the pass to trail makers or cairns at the 7.1km mark, where there is a steep descent into the forest. Stick to the left side below Mount Wilcox. At about 8.6km, the trail crosses to the left of the creek where it becomes more defined. Here the slope goes from moderate to steep on the descent south of Tangle Creek.
At 11.2km is the Tangle Creek trailhead (1860m) with the Icefields Parkway 200m south of
Tangle Falls and 10km north of the Wilcox Creek trailhead.
Otherwise, at the rock cairn the hiker can begin to backtrack the way they came to return to the Wilcox Creek Campground.
