Which side of the plane to sit from Denver International Airport (Denver) to Sloulin Field International Airport (Williston)?
Left Side of the Plane
The left side offers spectacular views of the Rocky Mountain Front Range immediately after departure from Denver, followed by the rugged high plains of Wyoming and the expansive Missouri River basin upon descent.
Rocky Mountain Front Range
Unobstructed views of Longs Peak and the snow-capped peaks of the Front Range shortly after takeoff from Denver.
Casper Mountain
A distinct ridge marking the northern end of the Laramie Range near the flight's midpoint over Wyoming.
Powder River Basin
Look for massive open-pit coal mines and industrial geometry in the vast landscape of northeast Wyoming.
Little Missouri River
Winding through the rugged badlands terrain of western North Dakota as the aircraft nears Williston.
Lake Sakakawea
The western reaches of this massive reservoir on the Missouri River are often visible during the final descent.
For the most dramatic mountain views, book an afternoon flight when the sun illuminates the Front Range from the west. In winter, the snow-covered peaks provide high-contrast views that are particularly photogenic. Watch for the dramatic transition from the urban sprawl of Denver to the empty expanse of the high plains within the first 15 minutes of flight.
The High Plains
A patchwork of agricultural circles and endless horizons typical of the Colorado and Nebraska borderlands.
Thunder Basin
Expansive national grasslands that showcase the rolling prairie ecosystem of the northern plains.
Black Hills Silhouette
On clear days, the distant silhouette of South Dakota's Black Hills can be spotted on the eastern horizon.
Theodore Roosevelt National Park
The South Unit's unique badlands formations and colorful clay layers are visible as you enter North Dakota air space.
Bakken Oil Fields
As you approach Williston, look for the intricate network of roads and drilling pads that define the Bakken formation.
The right side is ideal for morning flights to avoid direct glare while viewing the Badlands. Keep an eye out for the distinct 'Checkerboard' patterns of the plains. During night flights, look for the bright flares of the oil fields, which appear like a constellation of stars on the ground as you approach ISN.
