Astronomical Nights on Medellín's Hills: Clandestine Observatories
Medellín, surrounded by hills and blessed with a privileged climate, offers more than just nightlife and urban landscapes. On clear nights, especially between December and March, the sky reveals constellations, planets, and even the Milky Way from strategic points that few tourists know about.

The Secret Viewpoint of Las Palmas
Just 20 minutes from the downtown area, at kilometer 14 of the road to Las Palmas (before the toll booth), there's an unmarked turn-off leading to an abandoned concrete slab. Locals call it "La Terraza de las Estrellas" (The Terrace of the Stars). From here, with minimal light pollution, you can clearly see Orion, Scorpio, and Jupiter in season. Bring your own telescope or binoculars.
