Hiking trails along Highway 40

Kananaskis Country offers some of the most impressive hiking trails that are also not so crowded. Rawson Lake and Sarrail Ridge Trail in Peter Lougheed Provincial Park is a great option since it's easily accessible from Highway 40 via a small detour by Highway 742. The trailhead is located on the south side of Upper Kananaskis Lake, and the route is just 4.8 miles (7.8 km) both ways. Chester Lake, located north-west of Mount Chester in Spray Valley Provincial Park, is another spectacular hiking destination in the area. Ptarmigan Cirque and Highwood Pass, just off Hwy 40, is a must-see in Kananaskis Country due to its scenic mountain views and wildflowers. The 2.2-mi (3.5-km) mountaneous route starts in the Highwood Pass. It's most lovely in the fall, with golden hues all around.

Where to stay

Along Highway 40, you can find many designated campsites with various degrees of service from none to hot water showers and electrical plugs. For those who prefer more comfy accommodation, the towns and cities are within an hour or two from the highway with plenty of hotels to choose from.

The Highway 40 road trip would take about two days to complete by car. It's also possible to ride a bike, but keep in mind that the gravel sections of the road are rather challenging. Additionally, trucks passing by are a frequent hazard.
