If you are in the mood for some eco-travel, you should definitely explore the untainted wilderness of Gran Chaco, which has been virtually untouched by tourism for a long time. The region is sparsely populated, and only about 3% of the population of the country lives in the area, but the few towns and cities have small pockets of colonial architecture and they offer plenty of opportunities to discover the culture and traditions of the Guarani people.Nature lovers shouldn’t miss the Parque Nacional Defensores del Chaco, with its vast thorn forest teeming with wildlife (it’s better to visit it as part of a tour to avoid being eaten by pumas, jaguars or ocelots).
