Antofagasta, the capital of Chile’s Antofagasta Region (also known as the “Second Region”), is a major Pacific-coast port city located approximately 1,360 km north of Santiago. The metropolitan area is estimated at about 462,000 people in 2024 and is steadily growing.
Economically, Antofagasta plays a key role in the mining sector—especially copper and lithium—and its high per-capita income (around USD 37,000) highlights its prosperity.
Once part of Bolivia, the territory was ceded to Chile under the 1904 Treaty of Peace and Friendship. The city’s striking geography lies between the vast Atacama Desert—the driest on Earth and the Pacific Ocean, creating a dramatic contrast of desert and coast.
Economy & Innovation
Antofagasta’s economy is centered on mining exports, with copper and lithium taken from some of the largest deposits in the world.
The region is rapidly emerging as a renewable-energy frontier, hosting operational solar PV and concentrated-solar plants as well as ambitious green-hydrogen projects.
At the same time, desalination plants are gaining increasing importance across northern Chile. These facilities not only secure water supplies for the mining industry but also foster innovation in a nascent agricultural sector and provide drinking water for coastal communities, representing a major step toward regional sustainability.
Getting There
- The city is well served by major highways: Route 5 North (part of the Pan-American Highway), Route 1 along the coast, inland access via Route 26 and B-400. Multiple daily bus services connect Antofagasta with Santiago, Calama and Iquique.
- Andrés Sabella Gálvez International Airport lies about 24 km north of downtown and offers daily domestic flights to Santiago, Calama, La Serena and Iquique.

• Blanca Beach: popular coastal area in the city, especially on weekends. Supervision is limited, so caution is advised when swimming.
Mercado Municipal
Located at 776 Maipú Street, opposite Sotomayor Square. Since 1927, this vibrant marketplace and culinary destination features northern-Chilean specialties, regional products and elegant neoclassical architecture.
Antofagasta‑Bolivia Railway Station & Museum
The historic 1888 building on Simón Bolívar & Balmaceda was declared a national monument in 1981 and now houses the FCAB Railway Museum, offering family-friendly exhibits tracing the region’s railway legacy.
Tropic of Capricorn Monument
A monument marking the Tropic as measured circa 1966, located north of the city near the airport. The geographic latitude has shifted slightly to 23° 26′ 14″ S—a difference of 23 seconds from the original measure, an interesting geographic fact.
Hand of the Desert Sculpture
About 75 km south of Antofagasta on Route 5, this remarkable 11-metre-tall concrete hand was unveiled in 1992 by Chilean sculptor Mario Irarrázabal. Emerging dramatically from the barren expanse of the Atacama Desert, it has become one of northern Chile’s most photographed landmarks.
Free to visit year-round, it offers a surreal photo opportunity against one of the driest landscapes on Earth. Regular maintenance is carried out to remove graffiti and preserve its striking presence.
Astronomy & Stargazing Tours
Northern Chile is world-renowned for astronomy tourism. The region hosts major observatories like Cerro Paranal (home of the European Southern Observatory’s Very Large Telescope) and the Atacama Large Millimeter/submillimeter Array (ALMA) on the Chajnantor Plateau at around 5,000 m altitude. Since its inauguration in 2013, ALMA has delivered stunning images of cold cosmic structures. (Visits are possible only via educational, scientific or media programs, requested one month in advance.)There are also smaller local observatories offering experiences in San Pedro de Atacama.
Salt Flat & Nature
The Salar de Atacama lies about 300 km east (and ~55 km from San Pedro de Atacama) and is one of the world’s largest lithium reserves. At Chaxa Lagoon, visitors can spot flamingos, Andean geese, rheas, ducks, guanacos and vicuñas. Tours depart from Antofagasta and San Pedro.
