Arica y Parinacota Region (XV), northern Chile

Geography and environment

The region spans a sharp elevation gradient in a relatively compact area: a narrow Pacific coast and desert plain give way within tens of kilometres to steep foothills and the high Andean plateau (altiplano). Aridity dominates the lower zones, with parts of the Atacama Desert near the coast, while higher elevations support puna grasslands and wetlands. Notable natural features include Lauca National Park and Lake Chungará, along with the twin volcanic cones Parinacota and Pomerape on the high plateau near the Bolivia border.

Administrative structure and places

Arica y Parinacota is divided into two provinces: Arica Province, whose capital is the city of Arica, and Parinacota Province, which includes highland towns such as Putre. The region's population is relatively small compared with Chile's central regions, concentrated mainly in coastal Arica and scattered settlements in valleys and the altiplano.

History and culture

The territory has a long indigenous history, particularly of Aymara communities whose languages, social structures and agricultural practices remain influential. During the colonial era and the conflicts of the late 19th century — most notably the War of the Pacific — political control of coastal and highland areas changed, ultimately placing the present territory within Chilean administration. Today cultural life blends Andean traditions and coastal urban influences, visible in festivals, music, and local crafts.

Economy, transport and tourism

The regional economy combines international trade through the port of Arica, fishing, irrigated agriculture in valleys, and services linked to tourism and cross‑border transit. Arica serves as a logistical hub for northern Chile and neighbouring Bolivia and Peru; transport links include the Pan‑American Highway and Chacalluta International Airport. Visitors are drawn to beaches, archaeological sites, high‑altitude landscapes, and protected areas such as Lauca National Park.

Notable sites and facts

• City of Arica: coastal port, cultural centre and transport hub.
• Lauca National Park and Lake Chungará: scenic high‑altitude ecosystems.
• Parinacota and Pomerape volcanoes: prominent Andean landmarks.
• Strong Aymara presence: language, festivals and traditional agriculture.
