Yacuiba, Bolivia

Capital City

With a population of just 97,296, Yacuiba is a small Bolivian city that punches above its weight as a major commercial hub on the Argentine border. This fast-growing town has seen a boom in hydrocarbon exploitation, but its position on the frontier means bureaucracy is a persistent headache. The city's location also gives it a slightly cooler climate than the surrounding region, thanks to its modest elevation and monsoonal effects. Overall, Yacuiba may appeal to those seeking business opportunities close to Argentina, but the hassles of frontier life are not for the faint of heart.
