Climbing
The first ascent of Cerro Arenales was made in 1958 by a Japanese-Chilean expedition, headed by Professor Tanaka. In December 1963 an expedition led by Eric Shipton, crossed the NPIF heading southeast from Laguna San Rafael to Río de la Colonia and accomplished on the way the second ascent.[4]
