Great Divide Trail

The Great Divide Trail is Canada's answer to the PCT — except that unlike the PCT, large sections of the GDT are not marked, not maintained, and not trails in any conventional sense. The route follows the BC–Alberta border along the Continental Divide for 1100km from Waterton Lakes in the south to Kakwa Provincial Park in the north, crossing some of the most remote terrain in the Canadian Rockies.

The GDT was conceived in the 1970s and has been progressively documented, but it remains a work in progress. Approximately 60% of the route follows established trails; the remaining 40% is off-trail travel through alpine bowls, glacier margins, and boreal forest. Navigation skill is not optional — it is the primary competency the route demands. GPS tracks and the GDT Association's maps are essential, but real-time route-finding on the ground is unavoidable, particularly in the high off-trail sections of Jasper National Park and the northern BC wilderness.

Grizzly bear density on the GDT is among the highest of any long-distance route in North America. The Waterton-Banff-Jasper corridor is core grizzly habitat, and bears are encountered regularly by thru-hikers. Bear canisters or hang systems are required in the national park sections. Bear spray must be accessible at all times — a can buried in a pack under several kilos of gear is not accessible.

River crossings are a legitimate hazard. The off-trail sections cross streams that are not bridged, and in July the snowmelt runoff can make these technically difficult to dangerous. Cold, fast, thigh-deep crossings in remote terrain with a loaded pack are the GDT's defining physical test. Most thru-runners plan their July schedule around crossing conditions and carry a throw bag for technical crossings.

The northern sections in BC — Mount Robson Provincial Park through to Kakwa — are the most remote and the most spectacular. The approach to the north face of Mount Robson (3954m, the highest peak in the Canadian Rockies) is one of the great wilderness approaches on the continent.

Most thru-hikers take 45-55 days. Trail runners complete it in 30-40 days. The season is brutally short: before July 1, high passes are snow-covered; after mid-September, early snowfall is likely at altitude.
