Can you see Sa Talaiassa, Ibiza from Montgó, Dénia?
99.8 km line of sight toward the east (bearing 83°), computed on 30 m Copernicus terrain with Earth curvature and standard atmospheric refraction.

From Montgó, Dénia, at an eye level of 735 m, the sightline to Sa Talaiassa, Ibiza runs 99.8 km and clears every ridge in between. Over that distance Earth's curvature drops the target 680 m below a flat-earth line — but at 482 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 8 m above the terrain at km 99.7.

Frequently asked questions
Can you see Sa Talaiassa, Ibiza from Montgó, Dénia?
Yes. The terrain-limited line of sight is clear across 99.8 km, accounting for Earth's curvature and standard atmospheric refraction. Atmospheric haze is the only thing that can hide the view.
How far is Sa Talaiassa, Ibiza from Montgó, Dénia in a straight line?
99.8 km great-circle distance, on a bearing of 83° (east).
How much does Earth's curvature hide over 99.8 km?
At the target's distance the curvature drop is about 680 m: anything lower than that (relative to the observer's horizon plane) is hidden behind the bulge of the Earth. Sa Talaiassa, Ibiza 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.
