The primary obstacle isn't atmospheric haze or pollution—it's fundamental geometry. The Earth's curvature places the horizon at roughly 4.7 kilometers (2.9 miles) for an observer at sea level. Even from elevated coastal vantage points, the distance to Mallorca (approximately 200–250 kilometers from Valencia and Barcelona respectively) far exceeds the visual horizon.
Atmospheric refraction can bend light slightly, extending visible range by a small margin, but not nearly enough to bridge this gap. On exceptionally clear days, you might glimpse the outline of the island's higher peaks—like Puig Major (1,445 m)—through powerful telescopes or telephoto lenses, but unaided human vision simply lacks the resolving power.
So while Mallorca feels close culturally and historically, geographically it remains firmly over the horizon—a reminder of just how vast the Mediterranean truly is.
