Denver to Cancun is 1,671 miles (2,689 km), a flight of about 4 hours.
The Rocky Mountain Front Range panorama on departure from Denver is one of the most dramatic takeoff views in North America — a 200-mile wall of snow-capped peaks seen all at once. The Cancun arrival is beautiful but relatively brief. Right side wins overall for the sustained mountain spectacle during the long Colorado climb-out.
Flight Path
The flight tracks southeast over the Texas Panhandle and then south over central Texas, crossing the Rio Grande near Laredo or Eagle Pass. Over northeastern Mexico the terrain is the Sierra Madre Oriental range visible to the west. The Gulf of Mexico coastal plain of Tamaulipas and Veracruz is below before crossing the Yucatan Peninsula's flat limestone jungle to Cancun.
