The most important Inca road was the "Camino Real", as it is known in Spanish, with a length of 5,200 km (3,230 mi). It began in Quito, Ecuador, passed through Cusco, and ended in what is now Tucumán, Argentina. The Camino Real went across the mountain ranges of the Andes, with peak altitudes of more than 5,000 m. "El Camino de la Costa", the coastal trail, with a length of 4,000 km (2,420 mi), ran parallel to the sea and was linked with the Camino Real by many smaller routes.
