Sustainable tourism in South America is entering a new stage. Biodiversity conservation, participation of local communities, and the protection of natural areas are beginning to form part of a different way of discovering the continent. Argentina, Peru, and Brazil show three examples of this transformation.

Bonito, Brazil: the world's first carbon-neutral ecotourism capital

They already copied the model more than 40 countries. Conclusion for the traveler: booking in advance is key, demand exceeds capacity.
