Medellin is the biggest city on the list, and that is reflected by the skyscrapers and glowing lights that sparkle in the hillsides at night. While Medellin struggled with crime and the drug trade in the 1980s, it is significantly safer now, and areas such as El Poblado record very little crime. Medellin was named the Most Innovative City of the Year in March by The Wall Street Journal and Citi, thanks in part to its advancements in public transportation, which include Metrocable, a gondola lift system with several lines, and escalators.
There are beautiful natural parks throughout the countryside, among them nearby Guatape Lake and Parque Arvi Nature Reserve. The trip to Parque Arvi by Metrocable costs just $3, an indication of Medellin's low cost of living. The city also has five of the best hospitals in Central and South America.
