Which side of the plane to sit from Seattle Tacoma International Airport (Seattle) to Denver International Airport (Denver)?
Right Side of the Plane
The right side offers an unrivaled sequence of Pacific Northwest volcanoes immediately after takeoff, including a close pass of Mount Rainier, followed by a dramatic descent over the heart of the Colorado Rockies.
Mount Rainier
On standard southbound departures, the plane often banks around the mountain, providing an incredible close-up of the crater.
Mount St. Helens
Clear views of the horseshoe-shaped crater and the blast zone from the 1980 eruption.
Mount Adams
The second-highest peak in Washington is often visible simultaneously with St. Helens.
Great Salt Lake
In the distance to the south, the shimmering salt flats and water of northern Utah can be spotted.
Rocky Mountain National Park
During the descent into Denver, look for Longs Peak and the high alpine tundra of the Continental Divide.
The Flatirons
The iconic slanted rock formations of Boulder, Colorado, are visible just minutes before landing.
The right side is the 'volcano side.' Keep your camera ready within the first 15 minutes of departure. For evening flights, this side provides spectacular sunset views over the Rockies, though glare can be an issue until the sun drops below the horizon.
Mount Rainier
Depending on the departure path, the north face of Washington's highest peak dominates the horizon shortly after takeoff.
Sawtooth Mountains
The rugged, jagged granite spires of central Idaho's wilderness are visible mid-flight.
Grand Teton National Park
Look for the iconic sharp peaks of the Tetons and the Snake River winding through the valley in Wyoming.
Wind River Range
A massive stretch of glaciated peaks in western Wyoming, home to Gannett Peak.
Denver Skyline
On many approach patterns from the north, the downtown skyline is visible against the backdrop of the mountains.
Sit toward the front to avoid wing obstruction when viewing the Tetons. Morning flights are ideal for the left side as the sun illuminates the eastern faces of the Idaho and Wyoming ranges without creating glare on your window.
