Which mountain is the tallest in the Fitz Roy massif?

The tallest mountain in the Fitz Roy massif is Mount Fitz Roy, also known as Monte Fitz Roy or Cerro Chaltén.

Rising to 3,405 metres in the Southern Patagonian Andes, Fitz Roy stands near El Chaltén on the Argentina–Chile border. Its steep granite towers and frequently cloud-wrapped summit dominate the surrounding landscape and have made it an emblem of Patagonia. The name Chaltén comes from a Tehuelche term commonly translated as “smoking mountain,” referring to clouds that often form around the peak.

The mountain was named Fitz Roy by explorer Francisco Moreno in 1877, honouring Robert FitzRoy, the British naval officer and surveyor who charted parts of the Patagonian coast. The summit’s first ascent was achieved in 1952 by French climbers Lionel Terray and Guido Magnone.

Cerro Torre is often confused with Fitz Roy because both are iconic peaks in the same area, but Cerro Torre is a separate mountain and is lower. Fitz Roy also gives its name to the wider massif, making the question’s wording especially important: the highest summit and the massif share the same name.
