Salar de Surire is a high‑altitude salt flat in the Andean altiplano of northern Chile, located in Parinacota Province of the Arica y Parinacota Region near the Bolivian and Peruvian frontiers. The salt flat lies within an arid volcanic landscape framed by the Lauca and Putre areas and forms part of a larger Andean wetland complex recognized for wetland and avian values. It is notable for evaporite crusts, saline lagoons, and nearby volcanoes that shape local hydrology and ecosystems.
The salt flat sits in the Altiplano, close to the Chilean–Bolivian border and within the southern reach of the Andes Mountains, southwest of the Lake Titicaca basin and east of the Pacific Ocean watershed divide. Nearby settlements and administrative centers include Putre, Parinacota (town), and the city of Arica. Prominent geographic neighbors are the stratovolcanoes Parinacota (volcano), Pomerape, and Guallatiri, as well as the Lauca National Park boundary and the Río Lauca catchment. The site’s elevation around 4,200 metres places it among other high Andean features like Sajama National Park and the puna landscapes of Altiplano (Bolivia).
The salt flat is an endorheic evaporitic basin developed on Cenozoic volcanic and sedimentary substrates influenced by the Nazca Plate–South American Plate convergent margin. Regional ignimbrites, andesitic lava flows, and Pleistocene glacial deposits sourced from peaks such as Parinacota (volcano) contributed to basin infill, while tectonic uplift from the Andean orogeny isolated internal drainage. Evaporation of saline groundwater and ephemeral lakes produced strata of halite, gypsum, and other evaporites analogous to sequences at Salar de Atacama and Salar de Uyuni. Hydrothermal alteration related to nearby volcanic activity and past lacustrine episodes left mineralogical zonation and saline crust morphology.
The climate is high‑altitude cold semi‑arid, under the influence of the Humboldt Current and continental rain shadow, with large diurnal temperature ranges similar to conditions at Altiplano (Chile). Precipitation is primarily during austral summer via convective events linked to the Bolivian Winter and occasional moist incursions from the Amazon Basin. Surface hydrology is dominated by ephemeral streams, saline springs, and isolated lagoons fed by snowmelt from peaks such as Parinacota (volcano) and subsurface groundwater flow akin to systems feeding Laguna Colorada. The salt flat’s endorheic nature concentrates salts, producing seasonal crusts and brine pools with salinity gradients comparable to those in Salar de Coipasa.
The site hosts puna and high Andean wetland biomes supporting taxa associated with Lauca National Park and the Andean plateau. Vegetation includes cushion plants and halophytes comparable to communities in Altiplano flora and species recorded in Tulor region studies. Avifauna is especially significant: breeding and feeding populations of James's flamingo, Andean flamingo, Chilean flamingo, Andean goose, and migratory waders utilize the saline lagoons, linking the area to the flyways that include Salar de Uyuni and Laguna Colorada. Mammals such as the vicuña and culpeo relatives occupy adjacent puna, while amphibians and invertebrate saline specialists occur in brine microhabitats reminiscent of taxa described from Altiplano wetlands.
The area lies within the traditional territories of Andean indigenous groups historically connected to the Aymara people and pre‑Hispanic communities that engaged in camelid pastoralism and salt use, paralleling archaeological patterns found at Tiwanaku and along the Andean prehistoric trade routes. Colonial and republican period records reference transit routes between Arica and highland settlements such as Putre and Parinacota (town), and the salt flat has cultural links to ritual landscapes like those near Sajama National Park and ceremonial shrines on volcanic summits. Contemporary cultural values are reflected in local festivals, indigenous land claims, and pastoral practices coordinated with institutions such as regional municipal authorities.
The salt flat and its associated wetlands lie within conservation frameworks including the Reserva Nacional Las Vicuñas and are recognized under wetland protection mechanisms similar to Ramsar Convention‑listed sites in the region. It is subject to Chilean protected area management planning coordinated with the Ministerio del Medio Ambiente (Chile) and local municipalities, and conservation priorities align with those established for Lauca National Park, Sernageomin hazard monitoring, and transboundary biodiversity initiatives involving Bolivia partners. Threats include water abstraction, mining interests comparable to pressures at Salar de Atacama, and infrastructure projects debated by stakeholders including indigenous communities.
Access is typically from Putre and the Pan‑American corridor near Arica via unpaved roads that traverse altiplano landscapes frequented by tour operators servicing Lauca National Park and highland lagoons such as Laguna Chungará. Visitors often combine trips to nearby volcanoes like Parinacota (volcano) and cultural sites such as Parinacota (town); regulated visitation practices mirror guidelines used at Salar de Uyuni and protected wetlands. Facilities are limited; travel requires altitude acclimatization, permits for protected areas under Chilean rules, and coordination with local communities and park authorities for sustainable visitation.
