Floridablanca, Colombia

At 254,683 residents, Floridablanca may seem like a quaint Colombian town, but the reality is far from serene. Bureaucratic headaches abound, with the city's population skewing heavily towards transplants from Bucaramanga (44%) and other parts of Santander (33%). And while the tropical climate is pleasant year-round, the region's seismic activity - home to the second-most active fault line in the world - is a persistent source of unease. For those seeking a laidback lifestyle in the Andes, Floridablanca's charms may be outweighed by its logistical challenges.
