Smith Dorrien Trail is a very scenic drive located in Kananaskis, Alberta, in Canada. It’s a gravel road which travels through the heart of the scenic Smith-Dorrien Valley. The highest point of the road is the Smith-Dorrien Pass, at 1.905m (6,250ft) above the sea level. It's one of the highest mountain roads of the country.
The road (also known as Highway 742) is 62km long. It’s pretty easy to drive, no need for an SUV. The Smith-Dorrien/ Spray Trail (gravel-surfaced and rather dusty) stretches between the town of Canmore and Peter Lougheed Provincial Park, a distance of approximately 70km.
The drive is definitely worth it. There are many excellent photo opportunities here. Don’t forget your camera! The biggest issue is the dust from the gravel road. If you've ever driven on gravel roads before, the S.D. won't pose any major challenges. Watch for wildlife - lots of moose, coyotes, and the odd bear along the road.It’s pretty rough in sections and a narrow, steep winding grade near Canmore.
