Part of the Trans Canada or "The Great Trail" it travels the length of the Spray Valley through some of Alberta’s spectacular Provincial Parks. Often under cover in dense conifer forests, this well-built trail provides outstanding views as it climbs over rockslides and suspension bridges.

The northern end of this this trail begins at the Goat Creek Day Use area in Spray Valley Provincial Park, 1 km from the Banff National Park Boundary. Traversing through open meadows the trail crosses the Three Sisters Dam (Spray Lakes Reservoir) and continues south along the eastern side of the Spray Lakes Reservoir. Upon reaching the Driftwood Day Use area, the trail crosses the Smith-Dorrien/Spray Trail (Road)/Hwy 742 and continues south beyond the Sawmill Day Use area in Peter Lougheed Provincial Park, to once again cross back to the west side of the Smith-Dorrien/Spray Trail (Road)/Hwy 742 at the Pocaterra Dam (just north of Peninsula Day Use) at the north end of Lower Kananaskis Lake. 

The landscape along this long route is diverse with some sections travelling through thick forests and others climbing up and over massive rock slides, providing outstanding views across the valley. While much of the trail is new-build, many sections utilize pre-existing trails such as the lowest sections of Buller Pass, Rummel Lake, the Chester Lake Trail, the Chester-Sawmill Trails network and in the future, significant sections of the Peter Lougheed Provincial Park Trails Network.
