Highwood Pass is the highest paved road pass in Canada, at 7,238 ft (2,206 m). From the north, up the Kananaskis valley, the climb is 8.6 miles (13.8 km) at an average of 4.1% with 1,854 ft (565 m) of climbing, according to Climbfinder. PJAMM measures it a bit shorter and gentler (8.5 miles / 13.6 km and 1,670 ft / 509 m), starting at 5,515 ft (1,681 m); the difference comes from where each database starts counting and the elevation it uses for the pass.
What the climb is like
It’s a gentle, steady climb on Highway 40, through provincial park land with big views. The grade rarely goes above 7% except for the odd short kicker (Climbfinder gives a 10% maximum over 330 ft / 100 m), and it steepens a little in the last 1.2-1.9 miles (2-3 km). The pavement is good and the shoulder is wide, about 7 ft (2 m).
Many riders don’t start at the foot of the climb but farther down the Kananaskis valley, adding 12-16 miles (20-25 km) of rolling approach. The approach from the Trans-Canada Highway has quite a bit of traffic on weekends.
The spring closure: the best time to go
Highway 40 is closed to vehicles from December 1 to June 14, because of snow and to protect wildlife. Before it reopens there are usually a few weeks when the snow has been cleared but cars still can’t get through, and the road fills with cyclists. According to PJAMM, the best window is usually a weekday in early June. After it reopens, traffic is still light.
Wildlife is common here, including bears: don’t approach them, don’t stop next to them, and carry bear spray, as recommended throughout the Canadian Rockies. There are no services on the pass, so bring water and food.
Calgary is the nearest airport. The pass sits at about 7,200 ft (2,200 m): you’ll barely notice the altitude, but it’s worth spending a couple of days in Banff or Canmore first, where you can also climb Mount Norquay.
What gearing to use
With grades of 4-7%, a 34x28 is plenty. Work out your combinations in the gear calculator.
