Argentine province

San Juan

San Juan, land of the sun. In Ischigualasto, the Valley of the Moon holds the oldest dinosaurs on the planet, and in El Leoncito, the clearest skies open a window onto the universe. Between the Andes and the desert, oases of vineyards are born, where Syrah found its home, along with olive groves and pistachios. In Calingasta and Barreal, high-altitude wines at the foot of the Andes. Land of Sarmiento, of the Difunta Correa and of people who turned stone into an orchard. San Juan is not toured: it is illuminated. San Juan is the sun that gives life.

Natural wealth

The territory that defines it

San Juan is desert turned into oasis. Between the Andes and the Precordillera, meltwater irrigates the valleys of Tulum, Ullum, Zonda, Calingasta, Iglesia and Jáchal. In the north, San Guillermo National Park protects one of the largest vicuña populations in the country; in Calingasta, El Leoncito National Park offers some of the clearest skies in the world for astronomy, and the Pampa del Leoncito, a white clay pan where land sailing is practiced. The Cuesta del Viento dam, in Iglesia, is an international mecca for windsurfing and kitesurfing.

Ischigualasto, Valley of the Moon

A Provincial Park and UNESCO World Heritage Site since 2000, together with Talampaya, in La Rioja. Its strata hold the most complete sequence of the Triassic period, some 230 million years ago: some of the oldest known dinosaurs were found there, such as Eoraptor and Herrerasaurus. Its wind-sculpted formations —El Submarino, El Hongo, the Cancha de Bochas— make it an open-air museum.

El Leoncito, skies for astronomy

In El Leoncito National Park, in Calingasta, the dry air and the absence of artificial light make for some of the clearest skies on the planet. There operate the El Leoncito Astronomical Complex (CASLEO), run by CONICET together with national universities, with the 2.15-meter Jorge Sahade telescope, and the Carlos U. Cesco station of the Félix Aguilar Astronomical Observatory, of the Universidad Nacional de San Juan. Both are open to astronomy tourism.

Human wealth

The living figures

San Juan is the land of Sarmiento and of the sun, which sets its rhythm, its architecture and its table. The National Sun Festival celebrates its productive identity every February. The Huarpe heritage and Spanish and Italian immigration shaped a cuisine of kid goat, empanadas, pastelitos, raisins, quince sweets and olive oil, with wines born in high-altitude valleys.

Roots
  • Before the conquest · the Huarpe cultivate the valleys with irrigation channels; the Inca Empire incorporates the territory into the Qhapaq Ñan
  • 1562 · Juan Jufré founds San Juan de la Frontera
  • 1811 · Domingo Faustino Sarmiento, teacher, writer and President of the Nation, is born in San Juan
  • 1817 · one of the columns of the Army of the Andes crosses the mountains through San Juan
  • 1944 · an earthquake destroys the city; its reconstruction gave it the modern layout it has today

Productive wealth

What it produces and exports

San Juan combines two engines. Metal mining —gold and silver today, world-scale copper on the way— leads its exports. And oasis agro-industry: vines, table grapes and raisins, olives and olive oil, and pistachios in full expansion. India is today its main export destination, because of gold.

Exports 2025

USD 2,101 million, 11.1 % more than in 2024: 2.4 % of the national total and 48.6 % of Cuyo.

  • Manufactures of industrial origin · USD 1,857 M
  • Manufactures of agricultural origin · USD 181 M
  • Primary products · USD 64 M

Main destinations: India (USD 655 M, 31.2 %), Brazil (USD 91 M), Uruguay (USD 77 M) and Chile (USD 67 M). Main products: precious stones and metals and their manufactures, coins (USD 1,704 M), dried or processed fruit (USD 77 M), chemicals and related products (USD 72 M) and vegetable, pulse and fruit preparations (USD 61 M).

Mining
  • Veladero · gold and silver, in Iglesia · Barrick · 20 years of operation
  • Vicuña · copper, gold and silver from Josemaría and Filo del Sol, in Iglesia · BHP and Lundin Mining · approved under the RIGI in 2026 with a declared investment of USD 9,737 M, the largest mining investment approved under the regime
  • Los Azules · copper, in Calingasta · McEwen Copper · the first copper project approved under the RIGI, for USD 2,672 M
  • Gualcamayo · gold · approved under the RIGI for USD 665 M

San Juan is the province with the most mining projects and mining investment approved under the RIGI.

Vines and wine

39,684 hectares of vines in 4,241 vineyards: 19.8 % of the country's area, the second wine-producing province after Mendoza. Besides wine, it is the country's great producer of table grapes and raisins.

Syrah is its emblematic grape: it found its Argentine terroir in San Juan and is today the most planted red grape in the province. Its pioneers were the Langlois, a family of French origin who in the early 20th century brought vines from France to their model winery in Pocito. The oldest winery in the province is Graffigna, founded in 1870 in Desamparados.

In the Calingasta Valley, with Barreal at its heart, high-altitude wines are made from vineyards between 1,400 and 1,700 meters, with Syrah, Malbec and other fine varieties. Calingasta is the department with the most Geographical Indications in the province: Barreal (2012) and Valle de Calingasta (2013), joined later by Hilario, Sorocayense and Tamberías.

Olives and olive oil

Private sector · according to the San Juan Olive Chamber, the province has more than 16,500 hectares of olive groves, with 34 olive oil mills and 12 table-olive plants, and has become the country's leading olive hub. In Casuarinas, in the department of 25 de Mayo, SolFrut has its base: today Argentina's largest producer of extra virgin olive oil, it operates one of the largest processing plants in Latin America and produces more than 3,000 tonnes a year, about 10 % of the national total. According to the company, San Juan makes half of the country's olive oil, and 90 % of that volume comes from the department of Sarmiento.

Pistachios

Public sector · the Ministry of Production, Labor and Innovation of San Juan records about 6,000 hectares, projected to reach 9,000 in four years.

Private sector · according to growers, San Juan accounts for about 87 % of the national pistachio area, a crop that has grown more than 500 % in five years.

Jáchal quince

San Juan grows about 680 hectares of quince, 75 % of them in Jáchal, with Villa Mercedes as its production center. From there comes San Juan's blond quince paste, light in color, made without colorings or preservatives and with a tradition of more than two centuries, which the province protects with a designation of origin.
