From Illecillewaet Campground’s day parking lot, follow the markers to the trailhead. As the route makes its way into a thick, green, old-growth forest, it passes through a clearing that contains the remains of Glacier House. Five minutes in, the path splits, with signage sending you to the right (straight). Five minutes later another sign steers you to the right again.
There is a slight incline in the forest that quickly settles into a wide, flat path for about 500 m. A high bridge rises above Asulkan Brook, which marks the 1.2-km point of the trek. The hike pushes upward from the brook, and within a couple of short minutes a fork in the trail is accompanied by a sign pointing you to the left, marking 3.5 km remaining on this hike.
The next hour and a half or so is a climb of switchbacks through an increasingly thinning forest that allows the occasional view of Abbott Ridge, Mount Abbott and the Asulkan Ridge. The trail is surrounded by a variety of ferns, mosses, liverworts and broad-leafed shrubs. During the seemingly endless switchbacks, watch for the distinctive western hemlock with curved trunks. Because of the steep slope (causing a phenomenon called soil creep) and an impenetrable forest canopy, some of these magnificent trees begin life by careening out of the side of a bank on an angle, only to right themselves years later, creating a unique curved trunk near their base.
The grade continues, unrelenting in releasing progressively more astounding beauty as you move higher and higher. The forest progresses through the evolution to alpine within a short span of 150 to 200 m of elevation. The change is quite abrupt, and soon you are wandering over a boulder field that seems endless. This, however, is not the final destination. All sights in a 270° west, north and south arc are included in this stunning panorama, but the best is only another 134 m higher.
The view from the crest is magnificent. Lookout Mountain is 1.3 km to the southeast, while Young Peak is 4.1 km southward. The Asulkan Valley and Glacier are below almost directly south. Looking across the Illecillewaet Valley, you can easily spot Mount Sir Donald and Perley Rock along with the toe of Great Glacier. Breathtaking.
If you are feeling adventurous, continue down to the rocky exposure of the Illecillewaet Valley and proceed to the toe of the glacier. I would not recommend hiking on the glacier, though, unless you are properly equipped and knowledgeable. The unmarked, tailless region will gradually take you to the end of the Great Glacier Trail, allowing a complete, all-encompassing loop of these two marvellous routes.
Glacier Crest history
This ridge earned its name from members of the Appalachian Mountain Club in 1895. Glacier Crest is just that, a crest between the Asulkan and Illecillewaet Glaciers, providing spectacular views of both, with the Illecillewaet Glacier to the east and the Asulkan Glacier to the west. This sharp, narrow ridge was carved by glaciers that flowed down both sides of the ridge.
