Can you see Sant Jeroni, Montserrat from Barcelona (Tibidabo)?

Yes — you can

32.7 km line of sight toward the northwest (bearing -52°), computed on 30 m Copernicus terrain with Earth curvature and standard atmospheric refraction.

Catalonia's serrated holy mountain is supposed to be Barcelona's backdrop — yet from the beach the Collserola ridge stands in the way. From Tibidabo, the city's own summit, the geometry finally opens up.

From Barcelona (Tibidabo), at an eye level of 521 m, the sightline to Sant Jeroni, Montserrat runs 32.7 km and clears every ridge in between. Over that distance Earth's curvature drops the target 73 m below a flat-earth line — but at 1,207 m, it still rises above the horizon. The view is geometrically real: whether you actually get it depends on haze, not terrain.

Elevation profile from Barcelona (Tibidabo) to Sant Jeroni, Montserrat. Like every elevation profile, the vertical axis is stretched (≈5× here) — but the geometry is real: mid-path, Earth's surface genuinely stands 21 m above the straight line between the two points. Light bends only slightly around that bulge, so whatever it covers stays hidden.

Frequently asked questions

Can you see Sant Jeroni, Montserrat from Barcelona (Tibidabo)?

Yes. The terrain-limited line of sight is clear across 32.7 km, accounting for Earth's curvature and standard atmospheric refraction. Atmospheric haze is the only thing that can hide the view.

How far is Sant Jeroni, Montserrat from Barcelona (Tibidabo) in a straight line?

32.7 km great-circle distance, on a bearing of -52° (northwest).

How much does Earth's curvature hide over 32.7 km?

At the target's distance the curvature drop is about 73 m: anything lower than that (relative to the observer's horizon plane) is hidden behind the bulge of the Earth. Sant Jeroni, Montserrat 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.
