Mary Jane Cox, Jenny Feick, Chris Hart, Dave Higgins, Cliff White, and Dave Zevick surveyed an estimated along the proposed GDT route through public lands. Despite initially low enthusiasm from the Alberta and BC governments, whose representatives cited a lack of interest in the trail and a priority on resource development, the group founded the Great Divide Trail Association (GDTA) and began trail construction in the summer of 1976. By the mid-1980s, with funding from the Alberta government, crews had built 90 km of trail from North Fork Pass to Fording River Pass. When support from the province of Alberta ended, and logging and

use destroyed trails, work ceased, and the GDTA became inactive. In 2000, Dustin Lynx revived the GDT by releasing his guidebook ''Hiking Canada's Great Divide Trail''. By 2004, a group known as the Friends of the Great Divide Trail began to work on the GDT once again, particularly in the unprotected Alberta Crown Forest Reserve lands between Crowsnest Pass and Banff National Park. In 2013, the Friends of the Great Divide Trail re-activated the GDTA as a nonprofit corporation headquartered in Calgary. Since then, the association has conducted annual maintenance and trail-building throughout the length of the GDT.

, for the long-term protection of the trail. According to the GDTA:
The GDT is officially signed in portions of Sections A, B, D, and G, but elsewhere the GDT is not officially signed. Much of the trail within national and provincial parks is well marked but not identified as the GDT. The route is actually made up of several separate trail systems joined together by ATV tracks, roads, and wilderness routes. The GDT varies from being a well-developed, signed trail to an unmarked, cross-country wilderness route where navigation skills are required.
Since the trail follows the Canadian Rocky Mountains, it runs generally northwest–southeast, with the northern terminus being further north—equivalent to 5° of latitude—and west of the southern terminus. The GDT passes through five national parks, nine provincial parks, four wilderness areas, and four forest districts. The trail is commonly broken up into seven sections, A–G, based on access and resupply.


Section A

Section A runs approximately from the GDT's southern terminus at the Canada–United States border (which is also the northern terminus of the

.


Section B

This section connects Crowsnest Pass in the south to Kananaskis in the north. Nearly all of it is in public lands, with no designated campgrounds and no specific permits required. The section has undergone extensive route improvements since 2013, particularly the High Rock Trail near the south end. The trail was built to keep the route just east of the divide, avoiding private land, including the Line Creek Mine, on the British Columbia side. It passes features such as Window Mountain Lake and Domke Ridge. The High Rock Trail reconnects with the original GDT, built in the 1970s and 1980s, near where it re-entered Alberta at North Fork Pass. During the next north of this junction, the route passes points of interest, including Tornado Saddle and the Beehive Natural Area. North of Fording River Pass, the trail crosses into British Columbia and soon begins the longest road walk on the GDT, at nearly ; this can be largely avoided by taking the Coral Pass alternate route. The north end of the road reaches

Section C

In contrast to section B, the section C is entirely within provincial and national parks, requiring permits nearly the entire way. Because the GDT in this section uses some of the most popular hiking trails in Canada, it can be competitive to obtain certain campsites. In the south, the section starts at Kananaskis Lakes, before climbing over the divide into Height of the Rockies Provincial Park. This, the only area that does not require permits, ends in less than at the Banff National Park boundary at Palliser Pass. Passing Marvel Lake, the route enters Mount Assiniboine Provincial Park at Wonder Pass, visiting Mount Assiniboine and Lake Magog before returning to Banff at

, section C ends in the hamlet of Field, BC. Notable alternates in this section are the Northover Ridge and South Kananaskis Pass routes.


Section D

This is the southernmost section of the GDT with substantial stretches of unmaintained trail. The GDTA describes Section D, at , as the shortest section. Although Section F is about , the northern end is from a trailhead, so completing it requires a greater hiking distance. From Field, the main route takes an overgrown road up the Amiskwi River to Amiskwi Pass and requires the first significant unbridged river crossings that a northbound hiker will encounter. The popular Kiwetinok Alternate also goes north from Field. It takes maintained trail to Burgess Pass, the Iceline Trail, and Kiwetinok Pass. An off-trail route then reconnects with the main trail at the Amiskwi River about into the section. From Amiskwi Pass, the route leaves

at the Owen Creek trailhead and, once over Owen Pass, exit Banff National Park for the third and final time. For the next , the route uses unsigned but maintained trail in the Job/Cline Public Land Use Zone, and unmaintained trail in the White Goat Wilderness Area. Permits for specific campsites are not required. Highlights in this area include Michelle Lakes, the highpoint of the GDT at an unnamed pass, and Pinto Lake. At Cataract Pass, the route crosses into Jasper National Park and uses the Brazeau and Poboktan trail network, crossing Jonas Shoulder and Maligne Pass. North of the pass, the trail down the Maligne Valley to Maligne Lake had been unmaintained by Parks Canada for about a decade, leading to rougher hiking and camping conditions. In 2022, Parks Canada began once more to include the trail on official maps, renovate campgrounds, and allow the Friends of Jasper National Park and the GDTA to clear deadfall and overgrowth on the trail. This has improved trail conditions, although there are still unbridged water crossings. At the north end of Maligne Lake, the GDT uses the popular

Section G

The most northern and remote section of the GDT, Section G is a stretch of infrequently maintained trails and wilderness routes. This distance does not include the exit from the GDT's northern terminus at Kakwa Lake. From the northern end of Section F, the route continues northwest on the North Boundary Trail, classified as low-priority for maintenance by Jasper National Park, necessitating significant fords of Gendarme, Carcajou, and Chown Creeks. Crossing Bess Pass leaves the Smoky River watershed and Jasper National Park for Jackpine Pass and Blueberry Lake.

, Mount Morkill, Mount Fetherstonhaugh, and Casket Mountain. A junction with the Sheep Creek trail, which exits at Grande Cache, Alberta, provides an alternate route to pavement. Near Surprise Pass, the trail leaves the Willmore and enters Kakwa Park in BC. The main route descends to Cecilia Lake; the Surprise Pass alternate remains in the alpine and rejoins near Providence Pass, where another alternate branches off shortly. Kakwa Pass is the final pass for northbound hikers. The trail descends to Kakwa Lake, which has a free, first-come first-served public cabin maintained by volunteer hosts. From Kakwa Lake, there are two options for exiting the GDT by ground. The most common choice starts with a hike to the nearest vehicle-accessible road at Bastille Creek, and another on the Walker Forest Service Road to reach pavement at Highway 16. Alternatively, hikers can take a mix of trails east to the Lick Creek trailhead in Alberta.
