Sit on the Left side of the plane for the best views on flights from Denver to Boise. The left side delivers the more dramatic scenery overall. Departing Denver it tracks along the entire Front Range spine, and through the cruise phase the left side faces south toward the Sawtooth Range and central Idaho mountains as the flight arcs northwest. The right side is better only on the Boise approach itself.

During takeoff from Denver International (DEN), sit on the Left side for the best views. DEN typically departs westbound on runway 25L/25R, and the left (south) side gives you a clear look at the Front Range of the Rockies including the Denver metro spread below. As you climb and bank northwest toward Boise, the left side tracks along the mountain spine with excellent views of the high peaks. Notable sights include: Front Range of the Rocky Mountains, Denver metro grid, Mount Evans (14,265 ft), Rocky Mountain National Park peaks on the horizon.

When landing at Boise Air Terminal (BOI), sit on the Right side for the best views. BOI typically lands on runway 28L/28R approaching from the east, meaning the right (north) side faces the Boise Front foothills and the city itself. The right seat gets the Snake River Plain, the Boise River corridor, and the city grid on final approach. Notable sights include: Boise city grid and downtown, Boise River corridor, Boise Front foothills, Snake River Plain.
