Malargue is a city of 27,660 inhabitants (2022 census) in the far south of Mendoza province, at 1,402 meters above sea level, 425 kilometers south of Mendoza city via RN 40 + RN 146. Officially founded in 1950 but rooted in pre-Hispanic Pehuenche settlements, it is the gateway town to southern Mendoza — one of Argentina's least mass-touristic regions but with extraordinary attractions — and the obligatory access point to one of the continent's most unique geographies: the La Payunia Provincial Reserve, a protected volcanic field of 665,000 hectares containing the highest concentration of volcanoes in the world with more than 890 volcanic cones (per the Argentine Geological Institute), a UNESCO World Heritage candidate since 2011 (nomination ongoing), comparable in geological relevance to Yellowstone or Ethiopia's volcanic field. The volcanoes of La Payunia range from giants like the Payun Matru (3,715 m, extinct volcano with circular caldera) and Payun Liso (3,680 m) to thousands of small cones, volcanic lakes, solidified lava fields, black sand expanses like the Pampas Negras (30 km² of fine black volcanic sand where you can run barefoot), and the impressive La Pasarela canyon where the Rio Grande eroded basaltic rocks into a vertical cliff. La Payunia is accessible exclusively via guided 4x4 tours from Malargue (USD 130-180 full day, 420 km round-trip, 10-12 hours). Another unique treasure is the Witches Cave (Caverna de las Brujas), 70 km south of Malargue, a karst formation 5,500 meters in total development with 500 meters open to tourism, with colored stalactites and stalagmites, underground chambers called "The Virgin", "The Whale", "The Christ", mandatory 90-minute guided tour with helmet and headlamp (USD 25-35). 25 km west are the Pincheira Castles, natural volcanic tuff formations resembling medieval castles, the historic hideout of the legendary outlaw-hero Jose Antonio Pincheira in the 19th century. For winter tourism, Las Lenas (70 km west) is one of Argentina's largest and most exclusive ski resorts — 29 runs, 13 lifts, 1,230 meters of vertical drop, 64 skiable kilometers — famous for its "Marte" run, considered one of the best freeride runs on the continent. Ski season is June-September with daily passes at USD 95-130 in high season. Other attractions include the Atuel Canyon (turquoise waters), the Llancanelo Lagoons (Ramsar site with Andean flamingos), Valle Hermoso for trekking and fishing, and the El Azufre hot springs. Malargue is reached in 5-6 hours from Mendoza city (425 km), 2h30 from San Rafael (180 km north), or by bus (7 hours, USD 30-50). The Comodoro Ricardo Salomon Airport (LGS) has irregular flights. Notable cuisine: Malargue spit-roasted lamb (a regionally famous product), goat, carbonada, humita, southern Mendoza Patagonian wines. The city also hosts the Pierre Auger Observatory (international cooperation studying cosmic rays) and the Nuna-akoo Park (life-size dinosaur recreations).
