Learn what to expect when driving into Kananaskis Country and the Bow Valley, including main access routes, seasonal closures on mountain highways, and links to live road reports and gate status.

Driving into Kananaskis & the Bow Valley

Most trips to Kananaskis start on major highways from Calgary or Canmore, then continue on narrower mountain roads toward trailheads, lodges, and day-use areas. Conditions can shift quickly with elevation, weather systems, and time of day.

Plan extra travel time, especially in winter and shoulder seasons, and combine live road reports with weather forecasts and local advice before you go.

Before you drive

Use these tools together when planning your route:

Road reports & closures for live conditions and incidents.
Weather for forecasts by area and elevation.
Maps to understand distances, elevation changes, and gravel sections.

Trans-Canada Highway (Hwy 1)

The main east–west highway between Calgary, Canmore, and Banff. Many trips to Kananaskis begin on Hwy 1 before turning south toward Kananaskis Country or exiting into Canmore.

Expect highway speeds, higher traffic volumes, and changing conditions with weather systems moving through the Bow Valley.

Kananaskis Trail (Hwy 40)

The primary access route into Kananaskis Country from the south. Hwy 40 connects popular areas such as Barrier Lake, Kananaskis Village, Nakiska Ski Area, and Peter Lougheed Provincial Park.

Elevation increases as you head south and west, with cooler temperatures, more snow and ice in winter, and stretches with limited services.

Note: Sections of Hwy 40 have seasonal closures, see “Seasonal closures” below.

Smith-Dorrien / Spray Lakes Road (Hwy 742)

A scenic gravel road connecting Canmore with Spray Lakes Reservoir and Peter Lougheed Provincial Park. It provides access to several popular day-use areas, trailheads, and viewpoints.

Expect gravel surface, dust, washboard, and occasional rough sections. Conditions can change quickly with weather, and winter driving requires extra caution.

Other local roads

Smaller access roads lead to campgrounds, day-use areas, and trailheads throughout Kananaskis Country and the Bow Valley. Some are paved, while others are gravel or have narrower lanes and no shoulders.

Always obey posted speed limits and closure signs, and be prepared for wildlife on or near the roadway at any time of year.

Seasonal closures

Hwy 40 gates & seasonal road closures

To protect wildlife, reduce avalanche risk, and manage winter conditions, some highways and side roads in and around Kananaskis have seasonal closures. Dates and locations can change from year to year.

Common closure patterns

High‑elevation sections of Hwy 40, including Highwood Pass, have an annual winter closure (typically December 1 to mid June). Always confirm exact dates on Alberta Parks' annual road closures page.
Some day-use areas, campgrounds, and secondary roads are gated outside of peak season.
Wildlife corridor and habitat protection closures can occur at any time.
Avalanche control work or storm damage may cause short‑notice, temporary closures.

These patterns are for general planning only. Always check official sources for current gate status, closure notices, and restrictions before you travel.

Before you leave home

Confirm that your planned route, trailhead, or campground can be accessed when you intend to visit. Have a backup plan in case conditions or closures change.

Check current road reports on provincial 511 services.
Review seasonal gate status and road advisories from Alberta Parks.
Look up any special restrictions for your destination (parking, time limits, etc.).

Driving conditions

Mountain road conditions & driving tips

Conditions in the Canadian Rockies can change quickly. Even when roads are open, you may encounter snow, ice, gravel, standing water, or strong winds over short distances.

Winter & shoulder seasons

Expect snow, packed ice, and drifting conditions at higher elevations.
Winter or all‑weather tires are strongly recommended, carry chains where required.
Be prepared for sudden changes in visibility due to snow squalls or blowing snow.
Allow extra stopping distance and avoid sudden braking or lane changes.

Summer, gravel roads & wildlife

Watch for wildlife on or beside the road, especially at dawn and dusk.
On gravel roads, expect loose surface, washboard, potholes, and dust‑reduced visibility.
Reduce speed when passing cyclists, pedestrians, or parked vehicles at trailheads.
Heavy rain and summer storms can lead to localized pooling water or debris on the road.

Mountain driving essentials

Start with a full tank of fuel; services are limited once you leave Calgary or Canmore.
Carry warm clothing, water, snacks, and a basic emergency kit year‑round.
Download maps and directions in advance; cell coverage is limited in many areas.
Let someone know your destination and estimated return time.
