Can you see One World Trade Center from Bear Mountain, New York?

Yes — you can

66.6 km line of sight toward the south (bearing -179°), computed on 30 m Copernicus terrain with Earth curvature and standard atmospheric refraction.

From a summit in the Hudson Highlands, hikers photograph the Manhattan skyline floating 65 km downriver. The skyscrapers help — but how much of the city actually clears the horizon from up there?

From Bear Mountain, New York, at an eye level of 400 m, the sightline to One World Trade Center runs 66.6 km and clears every ridge in between. Over that distance Earth's curvature drops the target 303 m below a flat-earth line — but at 544 m, it still rises above the horizon. The view is geometrically real: whether you actually get it depends on haze, not terrain. The tightest squeeze is mid-path, where the sightline passes just 36 m above the terrain at km 2.7.

Elevation profile from Bear Mountain, New York to One World Trade Center. Like every elevation profile, the vertical axis is stretched (≈15× here) — but the geometry is real: mid-path, Earth's surface genuinely stands 87 m above the straight line between the two points (the dashed arc is sea level). Light bends only slightly around that bulge, so whatever it covers stays hidden.

Frequently asked questions

Can you see One World Trade Center from Bear Mountain, New York?

Yes. The terrain-limited line of sight is clear across 66.6 km, accounting for Earth's curvature and standard atmospheric refraction. Atmospheric haze is the only thing that can hide the view.

How far is One World Trade Center from Bear Mountain, New York in a straight line?

66.6 km great-circle distance, on a bearing of -179° (south).

How much does Earth's curvature hide over 66.6 km?

At the target's distance the curvature drop is about 303 m: anything lower than that (relative to the observer's horizon plane) is hidden behind the bulge of the Earth. One World Trade Center is tall enough to rise above it.

How was this calculated?

UpToWhere walks the full terrain profile between the two points on 30 m-resolution Copernicus GLO-30 elevation data, applying Earth curvature and standard atmospheric refraction (k = 0.13) — the same physics surveyors use. You can run the same point-to-point check between any two places on Earth.
