If you only do one “orientation” experience in Medellín, make it this. You’ll get context for the city’s past + present and see the contrast between the valley and hillside neighborhoods via the Metrocable—one of Medellín’s most meaningful (and uniquely Medellín) pieces of infrastructure. It’s the kind of tour that makes everything else you do afterward—neighborhood wandering, viewpoints, museums, even nightlife—make more sense because you understand the city’s layout, culture, and resilience.
