Nevado Tres Cruces Central, Stratovolcano in Atacama Region, Chile

Nevado Tres Cruces Central is the second summit of the Tres Cruces massif, an extinct volcanic complex in the Andes of Chile's Atacama Region. It reaches 6,629 m, with a prominence of about 610 m over the main south summit, and has a crater roughly one kilometre in diameter. A col links it to the south summit.

The massif is extinct, and the sources give no eruption date. The first ascent of the central summit was made by the Poles Stefan Osiecki and Witold Paryski on 26 February 1937. They climbed it together with the south summit, since the col between the two allows both to be attempted in one expedition.

The massif's name, Tres Cruces ("Three Crosses"), is shared by its three summits; the central one is distinguished as Central. The first ascent was made by the Poles Stefan Osiecki and Witold Paryski on 26 February 1937, climbing from the col that links the central and south summits.

Climbing here demands thorough preparation for extreme high-altitude conditions where oxygen levels are thin and weather can change rapidly. Access routes typically begin from lower elevations on the Argentine side or through mountain passes in the Chilean border zone.

The first ascent, on 26 February 1937, was made by the Poles Stefan Osiecki and Witold Paryski, who climbed both the central and south summits in a single expedition via the col joining them. The central summit's prominence of about 610 metres is measured against that south summit.
