What can you see from Willis Tower?
360° terrain visibility analysis from Willis Tower — observation point at 626 m, coordinates 41.8789, -87.6359.
From Willis Tower, the terrain-limited line of sight reaches up to 108 km. The single farthest piece of visible terrain lies 108 km to the east-northeast (bearing 74°), at 228 m elevation. These results account for Earth's curvature and standard atmospheric refraction, computed from 30-meter resolution Copernicus GLO-30 elevation data across 1,865,930 terrain samples.

Frequently asked questions
How far can you see from Willis Tower?
On a clear day the terrain allows a line of sight of up to 108 km from Willis Tower. The average visible distance across all 360 directions is 77.1 km. Atmospheric conditions (haze, humidity) usually reduce practical visibility below the terrain-limited maximum.
What is the farthest point visible from Willis Tower?
The farthest terrain visible from Willis Tower lies 108 km to the east-northeast, at an elevation of 228 m. Earth's curvature and atmospheric refraction are accounted for in this calculation.
How high is Willis Tower?
The observation point at Willis Tower sits at 626 m above sea level (Copernicus GLO-30 elevation model).
How is this visibility map calculated?
UpToWhere traces lines of sight in 360 directions from the observer using 30 m-resolution Copernicus terrain data, correcting for Earth curvature and standard atmospheric refraction. You can run the same analysis for any point on Earth with the free calculator.
