Calgary to Denver flight path: YYC to DEN

Sit on the Right side of the plane for the best views on flights from Calgary to Denver. The entire flight tracks along the eastern edge of the Rocky Mountains, so the right side offers continuous mountain scenery from Calgary's front ranges through Montana and Wyoming's ranges to Denver's Front Range on arrival, while the left side faces only featureless plains the whole way.

During takeoff from Calgary International (YYC), sit on the Right side for the best views. Departing YYC southbound, the Canadian Rockies foothills and front ranges near Banff and Kananaskis Country rise dramatically just west of Calgary, filling the right-side window during initial climb. The left side only shows the flat prairie stretching east from the city. Notable sights include: Bow River valley, Canadian Rockies front range, Kananaskis peaks, Calgary's western suburbs.

When landing at Denver International (DEN), sit on the Right side for the best views. On approach into DEN from the north, prevailing winds typically favor the south-facing 17-series runways, so the aircraft descends with the Front Range and Rocky Mountains clearly visible on the right, including foothills west of Denver. The left side shows only the flat high plains east of the city. Notable sights include: Front Range foothills, Longs Peak area, Denver's western suburbs, South Platte River valley.

The flight from Calgary International (YYC) to Denver International (DEN) takes 2h 15m.
