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 #10 Los Alerces National Park's ancient forests. At altitudes reaching 4,000 meters, the road system supported a communication network that was faster than the average medieval European route, enabling troop and supply movement across the Andes. 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.
