Qhapaq Nan — Andean Road System

Qhapaq Ñan—the Andean Road System—features over 30,000 km of trails built by the Inca and pre-Inca civilizations, with Argentina's segment covering approximately 150 km of well-preserved stone pathways. This archaeological marvel, dating back to the 15th century, includes terraces, tambos, and administrative centers that rival the engineering complexity of Los Alerces National Park's ancient forests. Concrete data: over 20 distinct archaeological sites are included in Argentina's protected portion, offering hikers a direct link to centuries of indigenous culture and craftsmanship.
