San Juan to Denver is 2,726 miles (4,387 km), a flight of about 5 hours 15 minutes.
While takeoff offers coastal scenery, the landing approach into Denver provides more dramatic and visually distinctive mountain views. The Colorado Front Range is one of the most striking geographic features on this route and dominates the final descent phase.
Flight Path
The flight path crosses the Gulf of Mexico (visible as open water for roughly 1.5 hours after takeoff), then the Texas coastline near Corpus Christi or Galveston, followed by the flat terrain of central Texas and Oklahoma. The Wichita Mountains in southwestern Oklahoma may be visible as low ridges. As you approach Colorado, the Texas Panhandle and New Mexico high plains appear as increasingly elevated terrain, with the Sangre de Cristo Range and Spanish Peaks visible on the left (south) side before the final approach to Denver's Front Range.
