The trailhead is the Mount Shark parking lot above Watridge Creek (5,600 feet, Mile 0) where the road from the town of Canmore along the southern side of the Spray Lakes Reservoir ends. A wide, recently maintained trail leads past Watridge Lake to the Trail Centre trailhead at the head of the reservoir, where there is a large map and noticeboard.
An alternative is to drive to Canyon Dam on the north shore of the reservoir and walk to Trail Centre along the old road (passable by four-wheel drive vehicles), which adds 1/2 mile to the route. From the Trail Centre, enter Banff National Park and take the trail sign-posted for Bryant Creek (5,600 feet, Mile 3.7) to Bryant Creek Warden Cabin (6,050 feet, Mile 8.5), where it is left for the trail to Marvel Lake and Wonder Pass which contours above the lake and then switchbacks up to Wonder Pass (7,850 feet, Mile 14), to enter Mount Assiniboine Provincial Park and descend slightly to Lake Magog (7,100 feet, Mile 16.8).
From the lake, follow the trail to Citadel Pass (7,740 feet, Mile 29), past Og Lake and through the Valley of the Rocks to re-enter Banff National Park and descend past Howard Douglas Lake and through the Sunshine Meadows to the ski resort of Sunshine Village (7,200 feet, Mile 34.8). The trail then leads over Simpson and Healy Passes to the popular Egypt Lake Campground (6,545 feet, Mile 42.5) and then up to Whistling Pass and down to the Ball Pass Junction Campground (6,300 feet, Mile 48). A climb leads to Ball Pass (7,250 feet, Mile 49.7), entry into Kootenay National Park and a long descent in the Hawk Creek valley to the Banff -Radium Highway (4,345 feet, Mile 55.7).
Across the highway, the trail climbs straight back up to Floe Lake (6,700 feet, Mile 62.2) and the start of the Rockwall Trail which is followed over Numa, Tumbling and Rockwall Passes to Limestone Summit (7,115 feet, Mile 78.2) and a descent to the trails end at a junction with the Helmet Creek Trail (5,770 feet, Mile 80.5), which is taken back up to Goodsir Pass (7,250 feet, Mile 83) and entry into Yoho National Park. A long descent leads down to the Ottertail River (4,855 feet, Mile 88.2) to be followed by an equally long ascent to McArthur Pass (7,250 feet, Mile 95.7) just over which the trail arrives at Lake O'Hara (6,675 feet, Mile 97). From the lake a final descent leads down the Cataract Brook valley to a parking lot by the 1 -A Highway (5,250 feet, Mile 105).
