Medellín’s urban renewal, following decades as one of the world’s murder capitals, has drawn international attention. Perhaps nothing symbolizes the revival more than the Metrocable, a system of cable cars that connect the city center to steep hillside neighborhoods that were once reckoned to be the city’s most dangerous. Grab a ride on Line K up to Santo Domingo and treat yourself to spectacular views. Once on the ground again, take a short wander around the neighborhood for a taste of the real Medellín and its friendly residents (known as Paisas), and see the small shops and the beautiful library whose original benefactor was the government of Spain. From Santo Domingo, another cable car continues to Parque Arví, an expansive nature reserve and weekend escape favored by overheated locals.
