Sit on the Left side of the plane for the best views on flights from Cancun to Denver. Left side wins both ends of the flight. The Cancun departure gives you the spectacular Caribbean coastline and lagoon, and the Denver arrival gives you the Front Range and city views. The right side offers Caribbean open water at takeoff and featureless plains on landing.

During takeoff from Cancun International (CUN), sit on the Left side for the best views. Cancun's primary departure runway (12/30) heading northwest means the left side faces southwest toward the Caribbean coast, the hotel zone strip, and Nichupte Lagoon. You get a clear view of the turquoise water contrasting with the narrow barrier island before climbing over the Yucatan interior. Notable sights include: Nichupte Lagoon, Cancun Hotel Zone barrier island, Caribbean Sea coastline, Isla Mujeres offshore to the northeast.

When landing at Denver International (DEN), sit on the Left side for the best views. Denver International sits east of the Rockies, and aircraft typically approach from the east on runway 16/34 or 08/26. On a southward or westward approach, the left side faces the Front Range of the Rockies including Longs Peak and the Denver metro sprawl, with the mountains as a dramatic backdrop. The right side faces the flat eastern plains with little of interest. Notable sights include: Front Range of the Rocky Mountains, Longs Peak, Denver metro grid, Cherry Creek Reservoir.

The flight from Cancun International (CUN) to Denver International (DEN) takes Approximately 4 hours 15 minutes.

The flight tracks northwest over the flat Yucatan Peninsula, then crosses the Gulf of Mexico toward Texas. Over Texas you pass above the Edwards Plateau and Hill Country. Continuing north over Oklahoma and Kansas, the terrain is flat agricultural land. As you approach Colorado the land rises gradually toward the Rockies. The Rio Grande valley and Sangre de Cristo Mountains may be visible to the left in northern New Mexico if the routing goes that way.
