Natural wonders of Atacama

The Antofagasta region of the Atacama Desert showcases extreme geological formations, including the world’s highest archaeological site atop the Llullaillaco stratovolcano. This high-altitude landscape features vast salt flats like Salar de Punta Negra and Salar de Imilac, which serve as critical Andean wetlands. Coastal landmarks such as the La Portada natural arch contrast with the volcanic interior, where peaks like Socompa and Lastarria define the border with Argentina. Cerro Armazones provides one of the world's clearest viewpoints for astronomical observation due to the region's hyper-arid climate.
