ONT → DEN
Which side of the plane to sit from Ontario International Airport (Ontario) to Denver International Airport (Denver)?
Right Side of the Plane
The right side of the aircraft typically offers the most iconic views of the American West, including a direct line of sight into the Grand Canyon and the most prominent peaks of the Colorado Rockies as you approach Denver from the southwest.
San Bernardino Mountains
Immediate views of Mount San Gorgonio and Big Bear Lake during the climb out of Ontario.
Lake Mead
The deep blue waters of the reservoir and the engineering marvel of the Hoover Dam visible in the distance.
The Grand Canyon
Stunning vistas of the North and South Rims, showcasing the immense scale and geological layers of the canyon.
Monument Valley
The famous sandstone buttes on the Arizona-Utah border can often be seen in the distance to the southeast.
Sawatch Range
A dense cluster of Colorado's highest peaks, including Mount Elbert, visible as you cross the Continental Divide.
Pikes Peak
The most famous peak in the Front Range stands prominently to the south as the aircraft aligns for its landing at DEN.
The right side is the premier choice for sunset flights, as the late afternoon sun illuminates the Grand Canyon's walls and the snowy Rocky Mountain peaks. Aim for a seat forward of the wing to ensure your view of the deep canyons and high alpine ridges isn't obstructed by the engine or wing structure.
Mojave National Preserve
Expansive views of volcanic cinder cones, Joshua tree forests, and the vast California desert landscape shortly after takeoff.
Las Vegas Strip
Depending on the flight path, the high-rise hotels and neon lights of Las Vegas are often visible to the north.
Canyonlands & Arches
Dramatic red rock formations and deep river-carved canyons near Moab, Utah, visible as the flight crosses into Colorado.
Grand Mesa
A massive, flat-topped mountain near Grand Junction that stands as one of the largest flattops in the world.
Longs Peak
The northernmost 'fourteener' in the Front Range, visible as the plane begins its final descent into Denver.
The left side is perfect for morning flights to avoid direct sun glare while looking north. Keep your eyes peeled about 25-30 minutes after departure for a glimpse of the Las Vegas valley. In winter, the contrast between the red rocks and white snow near Moab is spectacular from this side.
