Socompa

Volcano High Andean stratovolcano on Chile–Argentina border region

High Andean stratovolcano on the Chile-Argentina fringe notable to geologists and mountaineers; the region features barren volcanic slopes, high‑altitude salt flats and field research opportunities.

Main image

Socompa is a high Andean stratovolcano located on the border region between northern Chile and Argentina in the Puna de Atacama. The volcano rises to an elevation above 6,000 metres and is notable for steep flanks and evidence of a large flank collapse.

The mountain is of volcanic origin and its landscape includes lava flows, pyroclastic deposits and talus slopes shaped by past eruptions and mass-wasting events. It has been the subject of geological study because of its large debris avalanche deposit and well-preserved volcanic geomorphology.

Human use has been limited by the volcano’s remote high-altitude location, with occasional scientific expeditions and mountaineering visits. Infrastructure and settlements are sparse in the surrounding high plateau.

Socompa sits in the high Andes on the Chile-Argentina frontier in northern Chile’s Andean region, within an arid, high-elevation plateau landscape characterised by thin air, cold temperatures and sparse vegetation.

  • Elevation range: The volcano's summit exceeds 6,000 metres, placing it among the high Andean stratovolcanoes of the Puna plateau region.

Tips for Visiting Socompa #

  • Visit Socompa with an organized high-altitude expedition or tour operator that handles permits and local transport - the volcano sits in a remote, high-Andean environment with few services.
  • Plan travel in the austral summer (roughly December-February) when conditions are most stable and operators run more trips; allow extra time for acclimatization before approaching high elevations.
  • Factor in flexible logistics: local road and weather conditions commonly force schedule changes, so choose an operator experienced with the region and ask about evacuation and medical contingency plans.

Best Time to Visit Socompa #

Socompa (a high, arid Andean volcano) is safest to visit in the austral spring-summer when daytime conditions are least severe, but expect cold nights and high‑altitude effects year‑round.

Austal spring-summer
October-March · day ≈-5-10°C, night often well below freezing
Relatively milder days and drier conditions improve access; however Socompa is very high and nights remain extremely cold-altitude and thin air are major considerations.
Autumn-winter
April-September · ≈-30--5°C (wide variability by elevation)
Colder temperatures, greater likelihood of snow and difficult access; travel and fieldwork are more hazardous or impossible in severe winter.
