Cerro Mercedario is the highest peak of the Cordillera de la Ramada range and the eighth-highest mountain of the Andes.

[5] In 1968, after several attempts by some of the strongest Argentine climbers, a Japanese group led by Saburo Yoshida accomplished the first ascension of the south side.

In 1972, Italians Sergio Job Gino and Antonio Beorchia Nigris climbed the Mercedario through the normal route and discovered some Inca ruins just below the summit.

In January 1975 an Italian expedition led by Antonio Mastellaro managed to climb the east side.

On January 27 Mauro Collini, Sergio Figel, Mario Tavagnutti and Rudi Vittori reached the top.
